- In this video I discuss how well the Yong Heng compressor is holding up.
THIS IS PART 1. PLEASE WATCH PART 2 FOR IMPORTANT INFORMATION ON THE BLEED VALVE THREADS.
You are the first person who has done a make sense report on the Youg Heng
I think there are a multitude of reasons that people's compressors fail on them. I think it's more of a lack of understanding the physics behind it, and less neglect. I've watched several videos of people's repairs on their Yong Heng compressors. All of them revolve around the piston rings, cylinders, flapper valves, etc.... These are all parts of the high pressure side of the compressor. So here is my theory, and here's what I've done to avoid them.
#1. You are dead on correct when you say to bleed the air before turning off the machine. Not only does this drain the gross oil/water mixture that has collected in the compression process, but it relieves the massive amount of pressure pushing against the piston head. On the Yonh Heng compressor, there is only 1 piston. But it's a 2 stage compression process. The piston controls 2 functions- high and low pressure. Higher end compressors have 2 or more pistons. Each piston typically controls a specific stage in the compression process. If you ever removed the shroud from the cooling fan on the back of the compressor while the compressor is off, and rotate the fan, you can cycle the piston and hear/create a compression. If you can do that with your hand, imagine the force that would push against that piston if you stopped the compressor mid pump without bleeding off the pressure first. NOT GOOD!
But I think another problem people have, even if they bleed off the pressure before shutting off the machine is when they're pressurizing their air hose to charge the tank, and when the hose gets to the "approximate" tank pressure, and they open the valve on the tank. If the pressure in the tank is higher than the pressure in the compressor, then there's a massive push back against the high pressure piston on the compressor. It's very sudden and shocking, and it could be catastrophic to the piston if the pressures are significantly different. Knowing this, here's what I did. I suggest anyone and everyone who owns one of these compressors do this.
Buy this: www.amazon.com/gp/product/B07HL1M8XQ/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1
and this: www.amazon.com/gp/product/B004M37FYA/ref=oh_aui_detailpage_o09_s01?ie=UTF8&psc=1
This creates a self regulating, unidirectional check valve. You put this inline between the compressor hose and the tank hose. Obviously the air flow goes through the fill nipple adapter, and out the male quick disconnect. When I use this, I plug the male quick disconnect into the female quick disconnect on my tank, and open the valve all the way. Then I plug the fill nipple adapter end into the female quick disconnect on my compressor. The high pressure in the tank will close the valve on the male fill nipple from the back side (just like it does on the air cylinder on your air rifle tank). When the pressure on the compressor supersedes the pressure of the tank that's keeping the valve closed, the valve will open, and air will start flowing into the tank. It's self regulating, and it's seamless. It adds zero additional stress on the pistons of your compressor. You can actually see the point that the regulator opens because the gauge on the compressor and the gauge on the tank have subtle differences in "actual pressure" readings. You will see the gauge on the compressor move slightly, and the progress of the fill will slow significantly.
And because the valve is a 1 way check valve, when you open the drain valve on the compressor just before shutting it off, the pressure in the tank will close the valve again from the back side. Then you simply close the valve on your CF tank, and bleed off the air in the hose. All done, with zero imbalance or unnecessary pressure on your pistons or cylinders.
The 2nd issue people are having is with the aluminum (water cooled) heat sync on top of the cylinder head. It's corroding from the inside. When you add heat to unfiltered tap water, it mineralizes and calcifies. Not only does this eventually impede the flow of the water, but it promotes and expedites pitting and corrosion. So the fix to this is simple. Distilled water! Distilled water is evaporated and re-condensed. It has zero chemicals or minerals in it.
Get yourself a 5 gallon bucket, and buy yourself 3 gallons of distilled water. It only costs $1.50 per gallon. Keep the water sealed in the bucket with a lid. This can be your permanent cooling supply for your compressor. You just need to make room for it. The way you cool the water is to stick 2 or 3 water bottles in your freezer and get them frozen solid. When the temperature of the compressor starts to get close to the max operating temp, drop in 1 or 2 of the frozen water bottles. By doing this you can actually cool the water without contaminating it. It works flawlessly.
Also, when you're done using your compressor, and you shut it off and disconnect the water hose, there is STILL water sitting inside of that little hollow aluminum heat sync. Get a compressor with an air nozzle on it, stick it onto one of the little water intake ports, and squeeze it off. Stand back, because you will be AMAZED how much water comes out. But you can blow air into it for about 20 seconds, and get that thing bone dry inside.
So that's my input to your video. I'm not trying to hijack it or anything. I know other people (as well as myself) have spent a LOT of money on their compressors, and they want it to last as LONG AS POSSIBLE! Remember, a wise man learns from his mistakes, but a wiser man learns from the mistakes of others.
Thank you for the information. That all makes sense. I too have put a check valve on my cga347 fill whip. This way I can open the tank before start the compressor with any pressure on the compressor. Then start the pump once the pressure excess the pressure in the tank the one way valve opens allowing the tank to be filled.
Trinity Maker ?

Great info and very useful, thanks! However, I am still unclear what is the full process of opening/closing valve knobs on Yong Heng compressor itself. Mine is manual version and has two valves: one is called Pressure Relief Valve (its next to whip hose connection point) and other one is called Drain Valve (located on opposite end of the compressor, next to safety valve). When you say what is the exact sequence to open/close them when used in conjunction with 1-way check valve between tank and compressor as you described?
I just got mine today and the instructions say to have the bleeder valve open on startup, which is even more important. I also blow out the water lines when done. Why let that water stay in the water jacket? I use distilled water too. That was a no-brainer for me since I have well water. Good tips.
You said you aren't a genius, on this subject, compared to me you are! 😎 I'm just getting into the PCP airgun world and I have a lot to learn, this looks like a pretty good place to start learning about the special compressors and support equipment we need.
Could you please provide links for the filter tube, cotton filter and valve connection? That would be a major time saver. Your a genius
Great video... just ordered mine a few days ago. Unfortunately, I did not realize I needed further water removal, until I watched your videos ... thank you
Thank you for posting a video. I have recently acquired the yong heng 4500 psi air compressor and the tuxing filter , September 22 2019
Had mine for 6 to 7 months and love it.
I have had equally satisfying results with my compressor. As usual, your videos extremely thorough and very unbiased. I absolutely enjoy your content, keep up the great work.
Glad to see the Yong is doing good for you.
I got my Yong Heng today. Love it. No more hand pumping....no more scuba shops.
Good luck! Just don't over work it and run it as cool as possible.
I also purchased 2 spare shut off relays and a rebuild kit . Have had mine for about as long or longer than you have . I’ve had zero issues and haven’t used my spare parts yet . Like this compressor so much I actually bought a 2nd one just for fun 😂 and before everyone wants one and the prices go up ! There outstanding for the money 👍 only upgrade I did was bought a higher flowing water pump and it cools much better . Fantastic review!!
Thanks I have been waiting on that review I also have one and it works great but I need one of the bigger filters thanks again 👍
Thanks so much for this video along with the first one. I've been looking for a compressor, but do not want to spend a lot... Very help full
One thing to think about is getting out of those good filters with the activated charcoal and micro sieve combined. The air does smell like the hydraulic oil that comes out of this compressor but as far as I know it's not harmful to the guns. You can get them on Amazon or eBay for around $100
Great video. Maintenance is key to everything. As long as you use proper care and maintenance is done this compressor should last years. The other thing is as you said in the video use proper fittings these and any compressor are dangerous. Now i feel that after your video i will now drop the cash to order this compressor. Thank you again for your reviews.
My compressor automatically trips a twenty amp breaker when I turn it on? Any recommendations?
good video. watched all of them. The laws of physics makes your point about leaving it in stress. going to do exactly as you stated using the bleed valves
Thanks a Million for the great update & info... I've been waiting for this Video... :) I glad for you and the rest of us the the Yong Heng Setup is Going Strong....
Good Stuff man!!!
Ive Heard about the 30 year tanks. Ive heard tho. (Hear Say) That If You Have a Tank Extended Thru that Company for The 30 years that You have to go back to that company and that company ONLY to have your 5 year Hydro updates after the extension which depending on prices with them + shipping could possibly get expensive just depending but I dunno... Def worth checking into more. Plus ither way it good that they atleast started extending some SCBAs to 30years ither way regardless.
...Welp Thanks Again for the Update here and You have a Great Day man... PEACE!
so many thx - I need your very good explainings - because I bought the Yong Heng and the water sampler from Amazon - now HPA Tank 68/4500 - has 350 bar - for my Scuba Ringer and small airguns .
Lots of good information great job
The descent will hold a lot more moisture when the temp of the air is higher. But at room temp they both hold about the same amount. When filling your bottle the air will be warm making IMOP desiccant the better option. Good video.
Ty very informative, I'm just getting into the pcp market, always a fan of 2A.
I'll watch this video and a few more before I start my own
I have a more recent update
The pistons should be pushing the air through a one way check velve so when it shuts off and on the down strock there is no pressure on the piston. I don’t know about this particular compressor but I’ve never seen a HPA comp. without a check valve directly above the piston. If you ever take the piston head off. Usually incorporated with the burst disk (but not always) the check valve should be just a tiny spring and a fitted price of Deleon directly above the piston.
Thanks for posting this. Im in the process of adding the molecular seive to my set up. I like your bleeder valve idea, can you list the parts you used ? Thanks
I have a similar setup but I went another step further with another smaller filter after my gold tuxing gold filter ( that I too hacked with the pvc and industrial grade molecular sieve).
This final stage additional filter is slightly larger than the primary cotton one but I have blue / pink indicator dessicant sandwiched between the cotton filters.
I don't have a Yong Heng pump but a one that is similar...a Yong Heng knock off I guess. Hard to believe the Chinese would knock off their own products but there you go!
Had no issues at all but not had my gold filter vertical so maybe I should change that. Also, I like the bleed valve on the end of the tuxing, I think I will try that.... but my final stage with the indicating beads showed 0% moisture at the end of a full charge of a 4.5l tank.
Thanks for making the effort to post this!
Suggestion
On the valve on bottom of the gold filter install a tee, put a 2" long pipe nipple and bleed valve on the bottom of the tee to collect water. Connect the fill line from the compressor to the side of the tee. This will allow water to collect in the pipe nipple. This system is used on nateral gas service lines to collect water.
Wonder if he still doesn't know about this. Maybe he should read comments 🤣
I didnt know that Andy Garcia was into air guns. Good stuff man, good stuff. 😉
I thought this guy is the brother from Everyone Loves Raymond?
@@Google_Does_Evil_Now Yeah him too!
Videos are great. Thank you-
First off Thanks for the video. My ? is could you post a List of the parts needed for the filter and the fitting Part # or Link to them.
I've looked around but can't find what you have. Video time of parts starts at 4:59. Again thank you.
It's great that it's affordable and all. Great that parts are easy to find. What gets me is this after market stuff shown here. For fairly new PCP shooters this was like, uh, what did I just hear.
It's my opinion that with the amount of money being spent at every step of being a PCP air rifle shooter, at least the air pump should be out of the box ready. I did see someone mention that one of those parts now ships with it. I hope so.
Just an update to a common question! I have not been able to find the correct part to make the bleed valve work properly so here is what I plan to buy to replace or maybe add to the correct yellow filter I have. For $130 this sounds like a good all in one solution. You may also be able to find it on AliExpress. Here is the link to Amazon 30Mpa High Pressure Air Filter External Water-Oil Separator Filtration for Air Compressor Air Pump Scuba Diving www.amazon.com/dp/B077SX5G9V/ref=cm_sw_r_cp_taa_YkjFCbJ97FBBS
Also, use this one way quick disconnect nipple on the cga347 fill setup to be able to open the tank before starting the compressor and to be able to shut and bleed the compressor before shutting the tank with out losing air in the tank.

Great Video
Thanks 👌 👍 👍 👍 👍
The auto shut off I find helpful as I have 2 of thease that fill my 3 hpa tasks for airsoft 2 medium-sized and a small one the small one I run on one pump that is on auto and leave it to run whilst I keep an eye on the large tanks filling
Mine has the temp gauge already installed. Does it need a batt. The description on amazon said it uses a 357a
Great info. Subscribed 🤟🏻
I have this setup, the yellow filter door cap is blocked after single using, now im unable open it to look the filters inside the tube, but the compressor works fine
releasing the pressure BEFORE turning it off really helps. no more black oil.
Thanks for your videos, can i use ice with the water or use antifreeze /coolant 50 /50?
Very helpful video thanks alot Where i can get the one way check valve ?
great video , you look like a tv star
Are threads on both ends 1/8 BSPP? I'm wanting to add quick connects to both ends of Tuxing with one way on one side. Thanks.
So I found your channel and immediately subbed it because you are very detailed in your content! Do you still think that the Yong Heng is the best compressor out there to get now after so many years?
I too have the YH compressor and for about the same amount of time and, I too love mine. Yes, a nice new Omega or Daystate compressor would be more elegant but, when you can get these drop-shipped to your door for under $300 (Walmart), why? I can buy 6 YH compressors for less than the MSRP before tax and shipping vs 1 Omega.
PS: your channel is coming along nicely. I think your focus on wallet friendly mid-range PCPs is a plus. I've got the money for a FX Impact 700mm barrel but, by buying the Hatsan Hurcules Bully I saved over $1K USD and got a great gun, at a higher FPE and that is comparable in accuracy for hunting purposes. If I were competing for Extreme Benchrest 2019, well I might go for that Impact but, let's face it, 99.99% don't do that kind of shooting so why pay for that kind of accuracy when we will likely never use it?
very good video, thank you
powermate px p018-0084sp oil...is this a good compressor oil for yong heng?
Great vid! Just got my in today. Waiting for the desicant tube to come over from China. Anyhow, what size media are you using? 1/4", 3/16"? They come in a couple of different sizes. Thanks again!
From where did you buy desicant tube. Any link?
Thank you
You may want to think about getting a voltage regulator for the 110v stuff.
I'm the 1000th like ! Mine has a slow oil leak from running it with the oil cap on instead of a breather. I didn't know and mine didn't come with a breather. I don't think it's from the face, so where might be another place for a leak to form ?
This is my 3rd video I started to watch of yours, I couldn’t get through ant of them. Yes the material is what I want to hear, you’re very knowledgeable and experienced. I know more it’s my issue, but it would help if you would meet me in the middle by working on being more concise. I was forced to move on.
Great video, but I have one improvement, make one layer molecular sieve and one layer activated carbon or if you want, I don't know how expensive activated carbon is in the US, you can make a complete molecular sieve with activated carbon
And this is why I love springers.
Lol. Especially with so much talking here.
Is that molecular sieve 3a. Or 4a
I use an auto shutoff just for safety in case I'm not paying attention. I saw you get calcium deposits, maybe a little "CLR" in the water when you use it will get rid of the lime scale. Also if oil smell is an issue, you could just get another one or two filters to increase the cleaning effect of the air. I use it for my own scuba stuff. I have four filters including the little tiny one. Cotton, desiccant, molecular sieve, and carbon. Also scuba compressors use food grade synthetic oil, so it isn't dangerous really if there is an issue with some getting in the air. I have a small sailboat, a Catalina 30. I have this compressor tied into our 25 gallon tank with a 1.7 gpm pump feeding coolant water that basically always comes from a watermaker. So the water is blasting through the head compared to the little pump that came with it. Oh I added a vibration hour meter so I know when to change the oil. Another thing I added was a quite long(2x52") whip extension to allow me to fill tanks while leaving the compressor mounted in the cabinet. I also added desiccant filled pvc pipes on the air intake with valves to shut the air off so it doesn't fill the desiccant with water filled ambient air while not in use....since I am on the ocean I need a little drier air to go into the unit in the first place.
I have been looking at the Yong Heng's on ebay, I am noticing that these compressors don't have the Yong Heng decal on the side. The ones on eBay have a plate which reads YH. I remember you mentioned counterfeit compressors. Any feedback.
I bought this compressor about three weeks ago to fill my new Nova Liberty. I inspected both the rifle, pump and molecular sieve all seemed to be well made and clean. However, The pump manufacture suggested for first run to open bleed valves then with auto shut off set run pump unconnected until it reaches set pressure. So here what happened. The pump didn’t make pressure because the foster valve was bleeding air. So a checked my bench drawer where I keep the spare pump parts looking for a block off probe. So the question is does the foster valve act like the one on my shop air line or need a block off probe. Now that I’am into this I’am even getting more out of this video. Pumped the rifle up short of its max bars for a first test very little time to fill, low temperature and worked flawless. So question block off probe or no block off probe needed? Thanks again.
You will need the block the air off using a dead head adapter. Here is the one I use. The quick disconnect foster fitting will not stop air automatically. airtanksplus.com/product/dead-head-male-foster-fitting/
The reason that the air in your tank smells like oil is because there are microns of oil that slip past the filters and into the tank under the extremely high compression. The particles are so small they are almost vaporized (gas). If you go to the aquarium section of your local pet store, and buy some activated charcoal and mix it in with your desiccant beads, you will eliminate this. Activated charcoal is used in aquarium filtration systems to remove nastiness before it gets into the fish tank. It's also used in gas masks. It's the best filter in the world! And it's all natural. It probably wouldn't take more than 3 or 4 tablespoons mixed in with your desiccant should completely eliminate that issue. Or you could do separate layers of desiccant and charcoal. Maybe a layer of the desiccant, then a separate layer of the charcoal before it passes through the last cotton filter and into your scuba tank. Just a suggestion.
Thank you for the suggestion. I will try it.
@@AirVelocitySport did it work out?
Normally them separators are a 3 part system. An activated charcoal is one of the three layers in identical separators sold on eBay for it.
I need to do more research because I was hoping to pick one of these up for scuba tanks an actual breathing air. Maybe I’ll pick up two of the 2 of the 3 part separators and put them in series and get a third blank one and put cotton at the inlet and completely fill the rest with activated charcoal and a inch or two of the cotton. So it travels a full separator length of carbon.
@@AquaTech225 I just found this thing, I’m interested in building into my RV conversion to fill SCUBA tanks. The local shops compressor uses a food grade oil, looking into seeing if it’s similar to the “46” hydrologic oil. I would also fit it with the proper breathing gas filters, and have the air tested frequently.
@@evangelon2 Lube-V is what I used..synthetic food grade. I use my compressor for scuba I previously wrote to him->I use an auto shutoff just for safety in case I'm not paying attention. I saw you get calcium deposits, maybe a little "CLR" in the water when you use it will get rid of the lime scale. Also if oil smell is an issue, you could just get another one or two filters to increase the cleaning effect of the air. I use it for my own scuba stuff.

I have a question for you regarding your Tuxing water/oil separator. By no means am I challenging what you're doing, but I was curious why you opted to put the molecular sieve inside of a piece of PVC instead of straight into the aluminum tube that comprises the separator? I just purchased one myself. I even went out and bought the PVC and o-rings. Then as I started looking at it, I though to myself that it doesn't seem like the PVC is necessary other than you can visually see how tight the sieve is before inserting it into the aluminum housing. Because when the tube pressurizes, the pressure is exerted in all directions, not just trying to push the material forward in the direction of the air flow. So the PVC seems unnecessary other than allowing you to see and hear that the sieve isn't moving around.
But even if it did move a little bit, it still doesn't seem like it would matter, since the moisture cotton and the heavy duty end caps are containing everything inside anyways. I agree that the sieve or desiccant with some activated charcoal is a brilliant idea. But I was thinking that if you went to a hardware store or industrial supply store (or Amazon of course) and purchased some fine stainless steel mesh, and cut the mesh to fit the parameters of the aluminum tube, you could successfully separate your layers of components without having to mix them. The cotton has a lot of dexterity to it. So you don't need precise measurements. Especially if you put some of the SS mesh on each end of the cotton, facing the retainer caps. The retainer caps will compress them to make a tight fit. Also place some small rounds of SS mesh between the layers. The molecular sieve is great for instant water retention. The desiccant is great for long term absorption. The charcoal is great for removing vaporized molecules of oil and moisture. But the desiccant would remove the residual moisture from both the charcoal and the molecular sieve after you're done using the filter. It would slowly pull the moisture from the two aforementioned items. And the beauty of silicon desiccant is it lets you know when it's wet. It usually turns from dark blue to pink when it gets wet. When it gets pink, you can pull it out of the filter, pop it in the oven on 250 degrees for 15 or 20 minutes, and all the moisture will evaporate out of it. You can use it over and over again. You will see the color change back to dark blue.
Again, I'm not challenging your concept. It's brilliant. It makes a LOT of sense to me. I just don't really understand the necessity of the PVC pipe in the mix of things. But I love your videos. I've learned a LOT from them. Thanks for taking the time to make them....
The only reason for enclosing the molecular sieve in PVC to to prevent acid leeching from the sieve to deteriorate the aluminum walls and threads which over time could weaken the water/ oil separator. Just a precaution.
So does the compressor also have a water pump in it to circulate the coolant? I cant see a power lead going into your icebucket so i guess you do not have a submerged pump in it and i couldn't see a pump along the hoses from the compressor and to the icebucket.
Why did not you use charcoal inside the filter along with the disccant ? Is it because it is ineffective ?
I like my auto shutoff because I don't own a tank and fill the gun directly, My gun is a Wildcat and it has the gauge at the end by the fill probe hole, I prefer to set the auto shutoff and step away vs putting my face down by the gauge to tell when it is full.
Very informative... keep them coming... greetings from Chile. subscribed by the way!
Where can I buy the tube? Thank you
when you gonna post more vids?
Have you replaced the molecular sieve material since you built this water filter? If so, how many times? Any idea what the recommenced life is for the MS?
Standard desiccant you can bake the water out of in the oven I am told...otherwise you can buy it by the gallon on Ama-zon.
What’s your thoughts on also putting one of the little filter/dryer that comes with the Yong Heng on the fill line from the carbon fiber tank before it goes into the gun I’m thinking if there is any moisture in the tank this may help. Just my thought.
Air Velocity Sport I meant use one there also along with the other filters not to only use one there. Just a thought
Oh! Yeah I guess and extra one can't hurt.
There is a filter made with the bleeder on the side rated to 4500psi. Have you seen it ?
The air goes in the top center. Comes out near the top on the side. Bleeder is on the side at the bottom of the air chamber.
Yes, it's very nice and around $100. Thanks for that.
thanks 👍
what do you think is the best air compressor? I know air force has a new 1 that's portable & u can even plug it in a wall outlets or car battery $850 ..& air venturi has 1 that's similar but cheaper at $500 it's called the nomad 4500...great video & information
Gerald Williams I like the Hatsan lightening compressor for around $1300. I'm not a fan of the smaller portable compressors because of the limitations. But I can see where the portable compressors could be valuable.
Gerald Williams venturi packaging only all small compressor china made
How do I reroute from the power relay wiring to directly to the power as to no longer have the power relay connected? Thanks
Sorry if you already mention this, but where do you get those o-ring and what size do I need to get? Thank you.
Wannabe Mgtow I get my orings from harbor freight. Its a veraity of different sizes. I used size #216 metric which is 35.5 mm OD
What kind of oil are you using as I see in the forms lots of people saying use this and some say dont use this . What have you been running in it .
squidnutzs #46 hydraulic oil
looks like someone would have come up with a unload-er like large compressor which is a check valve that can be adjusted to activate with auto shutoffs work safely.
My question is. Are still on this first compressor in 2021? Or did it fail?
I am getting air pressure blowing from the black plastic part that sits in the oil filler space is that crackcase pressure and is the engine fooked?
I alsofitted 2 burst discs to get the pressure up to 4500 psi as before it was around 3500 psi
Substitute piston rings of 1st stage
If you add a second filter in the fill line, but gut it and load it with sieve and activated charcoal would the air become breathable air? Could you fill SCUBA cylinders? Any thoughts?
I'm not a SCUBA expert but I would say no way. I have seen a scuba operation and their filtration system is very complex. I would not take a chance and filling breathing air using a young hang compressor
where did you get the tank stand/holder? I have a smaller tank, but that is the type holder/stand i want.
Apple User...... he explained it in his very first video about the compressor.... he made the stand himself, it is Not a "store-bought" stand.
So In Order to make it work right will need an oil/water separator, filter dryer? Still lower than $1000.00 but workable
No, it will work just fine without the dryer but it's a good idea to have an dryer especially if you live in a high humidity area or run the compressor for more than 20 minutes at a time.
Could we get links to the components of the bleed valve
Good day , Air Velocity Sport , how is this compressor working out for you . I bought 2 of these compressor and they both have issues with passing excessive water and oil in my tanks. the first purchase was returned and I am stuck with the second unit because its too late to return it .. The compressed air also smells really nasty , it smells like a real messy , unclean , greasy mechanic shop . I have one of those huge filters on it but even with that the air still smells really bad and yes water still gets in, filter has to be changed after 2 or 3 fills . Thank you for your video .
Yes, I too have some small issues with oil and the air smelling a bit like oil. It's not too excessive. I have no issue with water since I use the dryer. My scuba shop will no longer fill my bottles until I have them cleaned because they do not want to take a chance of contamination even though they have check valve in place. But for $300 it's still well worth it.
@@AirVelocitySport Thank you for your reply , I think my problem with the two pumps I have tried so far is way more extreme when it come to oil and water getting mixed with the compressed air and getting passed to my tank. I have however solved the problem now by purchasing the Omega Air Charger . I really wanted these Yong Heng compressor to work but sadly it didnt, I would have paid double the price if it could just be 50% better designed and manufactured.
@@powersonic6255 I just bought a carbon filter. I have four filters...the small one, and three of the gold tubes with cotton, dessicant, and activated carbon. No problems at all. Just bleed the water every few minutes.
Dive shops used to charge cylinders in a tank of water. In the event of failure of the cylinder, the water mitigates the bang. There's a lot of energy in a full cylinder...
Will keep the tank cool too. Good tip.
Well the water may mitigate the bang, but if an air cylinder fails, it can kill people nearby. Incredible amount of energy contained. Years ago, there were several deaths from aluminum dive tanks that people had powder-coated and then heated, thereby weakening the cylinder walls. Some of them exploded upon being filled.
@@steveh8724 Indeed they did. Diver for 25+ years.👍
New to the PCP Airgun rifle life. Just recently got the air force Texan SS. Been using hand pump. Sucks! Rifle shoots great for an air gun.
My question is, as much as I’ve been writing down your parts you’ve been staying, apparently I’m missing some things. Do you have a list of every part name and part number from the name of the tank, size, part number, price, and then the fittings, 7 parts? I only heard you state 6?! I kept rebuffing the video to see if I missed it. And then the other fitting regulator next to the tank. And then the molecular sieve? Is that even the right way I’m spelling it? Sieve? And then then the length of that pvc pipe. I heard 1 inch. Anyhow, I’m planning on putting together one just like yours and even heard of another state about using charcoal from a petstore, to absorb the oil smell. Anyhow, good video, I’m still confused though. I got the compressor today and seen I need the oil and many other parts I’ve stated earlier. Appreciate your help also!!!

Hea, I just was looking & not sure where you are but if you have a FB account look up PCP Compressors & tanks their is a lot of help from guys that have these Yong Heng compressors. I been using one for a few months now to fill up my Condor & have a 3 Lt tank coming in this week. You can also Check Ali Express as they sell parts for the Y H. Hope this answers your questions sorry i didn't see your questions sooner.
Rob Withman
Thanks Rob!!! Much appreciated!!!
Is there any reason a guy couldn't skip using the PVC pipe? Push the cotton filter all the way to one end, fill it up with the absorption material, add the second filter, screw the cap back in place and be done with it. No unfiltered air could slip between the outside of the 1" PVC pipe and the metal tubing wall.
Hello, I have watched your videos and am very excited and enlightened with the information divulged by you. I too am interested in the PCP air guns and am thinking of investing in the FX Crown sometime later this pandemic subsides.
But, unfortunately, I am in India and the PCP air rifle is not so common and neither is Scuba diving as a sport. Thus, getting dry air at 250 Bar is very rare to come by, at best, and non existent normally. So, if I am to pursue the sport, I need to import all the equipment and the accessories!!!!!
I asked a local air compressor company (Ingersoll Rand) for the cheapest system that could give clean, dry air at 300 Bar and they actually gave me a quote for a "monstrous" system which would set me back by about USD 31,506/- to be precise, air dryer and scuba tank aside. I was unsure as to whether should I cry or laugh.
I seem to have come to a grinding halt.
Can you order from krale sport! They have many FX airguns. You could also purchase a Yong Heng compressor from eBay for around $290. You could find SCBA tanks online. Do they not ship to India? Yes, airguns are lots of fun but very expensive when you consider everything you need to buy to get started. You could buy a $300 Airgun and a $75 PCP hand pump but PCP Airgun uses so much air that you will not enjoy shooting if you have to hand pump your Airgun. I wish you lots of luck
@@AirVelocitySport Thank you for the reply, yes, I will look it up, but if all else fails, import is my only option.
Please keep up your videos, they are very informative.
Can i use this compressor for cng
I don’t see how an auto shut off can stress the unit, there is a check valve that prevents pressure from going backwards in the system. Or am I mistaken?
Not sure if there is a check valve. Good point.
you're right. it has a check valve, no need to bleed before shut off.
Shouldn't the YH be entering the Tuxing on the top not the bottom so that gravity would bring moisture down through molecular seive?
... so to let the pressure push the water into the tank ?? is your brain molecular ?
They should be sending you free stuff. I am just getting into getting a PCP Air rifle to shoot in my backyard and shot iguanas in south Florida, have 10s of them each day in my yard. All young and going to get big. So i am getting ready for them. I will buy this compressor. can i pump it directly into mt Hatsan Rifle. Hatsan Flash. Plesee advise. I will get a scuba tank as well. They are cheap here certified and on Craigslist for $60 to 100, and infact $6 bucks to fill. don't need the hasssle of going back and forth.
Yes, the yong Heng can fill directly into your Airgun. Check out Erlis Vidal on you tube. His channelm is iguana Hunter. He is also in South Florida. Good luck and safe shooting
Im on the process on choosing a 4500psi scba tank, omega or joe bracanto air tank, which do you recommend
It really does not matter as long as it is DOT certified. I personally try to get he best value.
Why does the desiccant have to be in a tube? Great instructional video.
It is supposed to hinder acid leaching from the molecular sieve / desiccant to deteriorate the walls of the aluminum tube or the threads. I am not 100% sure if that is fact or just fear-mongering buy vendors.
The simple answer is that excessive moisture in the air is produced while under pressure, which must be dealt with BEFORE entering the storage tank (while under pressure). Thus, a process is needed while under 4500 psi to remove the moisture prior to entering the storage tank. And yes, you are correct about the subsequent acid problems if water is allowed to enter the storage tank.
@@CaliforniaTravelVideos so using the PVC is recommended.. rite?
@@tropicthunderbolt Yes - Presto :)
Does that little compresor get the tank full? Also how long does it take to fill it up?
Yes, when the seals are new topping off from 3000 psi to 4100 psi is 15 minutes. Do not over work this little compressor as it's not meant to run from long periods of time without wearing out. But it's a great little compressor for topping off big tanks.
Where did you get the boot for your scba tank mine came without the base and would like to find one that fits 60min scba tank. Unable to find online. Just asking. Thanks
Vinny C the boot from eBay and Amazon. About $18. The tanks are harder to find now. You have to keep checking.
Air Velocity Sport that’s one place I haven’t checked. I have a cpl of the tanks. Just missing the boot. Thanks for reply
I realize this is an older video. can you recommend , by giving a web page address for a Yong Heng Compressor today
The warranty seams nice, but some are complaing they're not getting the Yong Heng compressor. Like you I would like one without the auto shut off. thx
Still Amazon and ebay have the best prices.
You mentioned that you use ice to cool down the cooling water, I’m a marine engineer by trade and we are taught that cooling water must not be too cold as it may induce thermal shocking of the components in the water jacket of engines, same applies to compressors, just something to bear in mind, I appreciate you can’t have constantly replenishing running water due to your circumstances however I’d personally recommend just topping the coolant off with cold water as it increases in temperature as oppose to ice.
Good to know I was thinking of a bucket dropping clumps of dry ice in
what do you think of using auto coolant instead of water. it does protect against corrosion. Or 50/50 glycol solution that is used for high powered LED cooling systems? thanks.
Others on the video have also suggested coolant. I'm not sure but it sound viable. I may try it down the road.
Anti freeze will not work it’s mainly used to keep car engine for freezing. In the summer you can use plain water in your car. Plus the chemicals in it may deteriorate your rubber o-rings.
I believe you're right. I used distilled water and it's been good.
How much air do you put into your 4500 tank. I only seem to be able to get about 4200. I have HG with a Auto shut-off, not an adjustable shut off. The needle bounces towards the end. Any tricks you know of? I was thinking of changing it for an adjustable shut off. But maybe 4200 is okay. I refill my tank when it hits 3000 psi.
I only fill to about 4200 psi as well to save the orings on the high pressure Piston. They seem to last quite a bit longer just by not pushing to 4500 psi. Remember, the yong Heng is only a 300 bar max pressure compressor which is 4350 psi. Yes, I like the non auto shut off better. It simply has less components to go fail. The power relay failed on my first auto shut off compressor.
@@AirVelocitySport Which model of the HY do you have now. manual shut off? Auto stop at 300 bar or the adjustable shut off.
When do you refill your bottle. I have a Scott 30 Min. So I refill as it gets below 3500 I have a Hatsan AT 44 Looking at your Kral Pro 500. Hatsan has a 20% off sale. So I have been looking at the Nova Star. It is at $650 and has the carbon fiber bottle already. any thoughts.
Where does one buy the high pressure rated fittings?
Some of the basic fittings and bleed valves, NPT only but none of the BSPP or metric thread stuff. airtanksplus.com/product-category/pcp-airgun-fittings/
How is ur yong heng workg .alex
What should I do
you can now buy these with the molecular sieve granules already in from ali express
You are awesome . I just saw your video 👍👍👍👍👍🗽🇺🇸🤔
Thank you, I'm just OK. It's you who is awesome.
@@AirVelocitySport I really like your video .i am a disabled Vietnam veteran .i an trying to get a veterans shooting team going for our golden age games .you just may have saved us a whole bunch of cash . mow we can look at Pcp rifles . the cost was a big concern of ours . wow great stuff YOU CAN bet your video will be shared with my chapter of the disabled American veterans and Vietnam veterans of America .very very good thank you some much 👍👍👍🗽🇺🇸
Wow! I'm so glad my video helped. Thank you for your service to our country. One thing I want to mention is don't use hydraulic oil as it burning to easy and leave residue on the high pressure piston. plus it smells? I use something called secco lube 500 (1 gallon for $59 at www.filtertechs.com - it will last a long time) which his much cleaner. I have other people tell me they use Royal Purple oil.
@@AirVelocitySport thank you for that .may I ask what you do use .this is so helpful .this is viewed by over 3000 veterans next Monday . I have having our commanders shart to all members in our email list .this is so helpful
This saves us 1000s . that means more rifles for the golden age game this spring .👍👍👍👍🗽🇺🇸
Tim I was a business analyst for many years but I renovated homes on the side. Thank you for sharing.
I use this compressor for almost a year now but I only could fill my scuba tank up to 3000psi.no problems. I now have a 4500psi carbon tank but after the pressure gets over 3200psi the compressor sounds different, it fills slower the temperature rises faster, overall it seams like it's struggling. Is this expected?
Yes, I too have noticed when topping off my 4500psi tanks it sounds different after 3800 psi. It's normal. These compressors are only 300 bar not 310 bar. So dont push it too hard. I only run it for 13 minutes at most with a solid block ice thats 2 gallons. It runs at about 47 Celsius.
@@AirVelocitySport thanks for the fast reply. So is their any info on service time? Piston , O Ring's , gaskets. I can find anything online.
Can you tell me where you´ve got the filter from?
Search on Amazon or Ali Express for Tuxing 30Mpa Oil Water Separator. Make sure to get the micro sieve version.
