- Choosing the right compressor can be confusing. Everyones situation is different, I'll explain what to look for and what to expect out of your compressor. Check out my other videos on HVPL Basics.

I love your teaching style. You’re videos on compressors and paint spraying are unparalleled! Great work!
This is the best video I've seen on the topic. Simple to understand and covers everything quite well. 👏👏👏
helpful, much appreciated.
everyone talking about the audio must be old, i feel like my hearing is shit and im a locomotive mechanic with plenty of loud noises around me all the time but i heard him completely fine
Super helpful info! I've been trying to figure out what equipment I would need to repaint panels of a truck and this was just what I was looking for.
Well done. One of the few videos that explains that a DIYer can do a lot with a small compressor if they are willing to wait patiently when air gets low. I sprayed my Jeep with almost the exact same setup using very similar compressors. I used a T and 2 check valves. With compressors running on separate circuits I rarely had to wait. Of course a pro would never be willing to wait as time is money so that solution wouldn’t work for them.
Thanks 👍
Really good info. Small compressor for small projects. I first got 100 gallon used propane tank for free and used that with a Craftsman 25 Gallon home style compressor (125psi). Worked great and I added a computer style muffin fan on top of the motor (I cut a hole into the plastic shroud) fan ran continuously to keep the motor cool even between cycles. Motor lasts a long long time **if** it is stays cool.
Great job
If you are a professional spray tech who does 10 cars a day of course you need an 80 gallon that puts out 25CFM. DIYers can use their current compressor, but use a low CFM gun.
I have a 80 gallon Ingersoll Rand TS4N5 great machine ! Never run of air , but have use a 10 gallon in the past to paint a riding mower it worked just gotta be patient with the recovery. But anything I under 26 gallon is pushing it in my experience. But others may have had better luck !
Wow, thank you sir!!! Appreciate the video and help me out another after hundreds of research. Liked & subscribed to you fam. 😀👍
I didn’t know if and what compressor would work with my new cc500 for mobile headlight repairs and you just helped me a lot, much appreciated and good explained video! (They’re tripping with the audio, it was clear)
Thanks, very useful info.
Volume a bot low but I heard you fine. Glad you shared. I have a cheap hvlp thinking of spraying my pine doors with water based poly. I have that same compressor and the cheap HF upright like 30 gal but regulator sucks. Doesn’t run my finish nailer like the pancake. Maybe need to upgrade regulator? Which one do you think is better? Thanks for vid.
thank you for the video. very helpful
Thanks alot your video, super useful!
I could use some foam for insulation on my thermal battery for my tubine.
Hi Tom, I am using a husky gravity-fed hvlp gun to paint some furniture I have (dressers) and I'm wondering what compressor you recommend for this?
I use 20 gal Husky but with a LVLP Gun saves Lots of air and painted a whole car no problem, psi Never dropped below 125psi 👍
Which LVLP gun did you use?
@@commentator2.0 I use the AeroPro Gun
@@redbaron2448 thanks for the reply! Hadn’t heard of that one but looks to be the same as the SPRAYIT branded one I was considering. So I will give one a try. Thanks
@@commentator2.0 Your welcome and Happy Painting
Hi Tom,I recently started spraying kitchens/furniture using mainly water based coats,what psi do you recommend for a nice finish,I have a 50ltr 14 cfm compressor, any advice appreciated thank you
Great video thank you
Thanks, great info!
Your Welcome
Thank you so much for sharing and, by the way, I hear you perfectly. This is the kind of explanation I was waiting for. I wonder why most people say that you need to match the gun cfm requirement with the compressor cfm delivery. I think it is because they are referring to painting cars. As a woodworker, I have used HVLP guns with a 2.4 cfm pancake compressor. Recently, I acquired a 14 cfm HVLP gun and may need a bigger compressor but will make the test first. If I can paint a cabinet door which takes about half a minute without catching up, that is enough for me.
I can hear just fine. And ive got 35 years of playing drums in me🤷🏻♂️
Thanks for this
Once I blasted the audio , good content .
Yeah, sorry about that
@@imagineform It actually helped me out tremendously thank you
Great video! I found it super helpful. Does anyone know if Dewalt DWFP55126 (165 PSI, 2.5 SCFM@90, 6 gallon) or Dewalt DWFP55130 (200-PSI, 3.0 SCFM@90, 2.5 gallon) will be better for spraying?
I would go with the 6 gallon, it will kick on less often
I have a 30 gallon Husky, 5HP with a 10CFM output. I am able to use most HVLP guns that use 4-7CFM
How much did it cost?
@@brandonpacheco6125 $100 in 2000
Tom, don't know what's wrong with your mike, but man, I could hardly hear you.
It doesnt work.
We hear him perfectly fine.
Hi Tom, thanks for the video, it did clear up the cfm area of need for me. Newbie question though, what about the fact that these compressors tend to also 'spit' water? Don't you need a painting specific type compressor to overcome this? Thanks
All compressors will accumulate water, they need to be drained occasionally. There are also dryers you can add after the compressor and befor the gun. These can be expensive cooling units for large volumes or simple passive ones for smaller.
@@imagineform Thank you very much
Great clear info thx. Never understood what 'latex' paint is ? Latex is rubber? I'm in UK by the way we don't use that term for paint.
Yes it is latex. You can see videos of water leaks where it gets trapped behind the paint and causes huge bulges lol
Not very sandable, but is durable, covers good, and lays flat.
Legend❤
Are you not supposed to keep spraying as the compressor kicks on to refill the tank? I have an Iwata LPH-50 HVLP that only uses around 2.2 CFM max and my tank can supply around 4 CFM @ 40 PSI. My Iwata only runs at 13-14 PSI. My gauges still read the same 13-14 PSI (working pressure) when the tank, a 4.4 gallon, kicks on but am I supposed to stop and let it completely refill?
No, you can keep spraying as long as you still have the pressure. If it runs too long it could over heat though.
@@imagineform Ok, thanks for the info!!
can we use aircompressor for tires on spray gun? i barely can find those in your videos , and if i do its freaking expensive
Not unless you are using a larger compressor to fill up your tires. Compressors needed for paint spraying are spendy.
I have a 20 gallon/ 125psi
Displacement 11.7 scfm
Maximum delivery 6.6 scfm at 125 psi
Is this a good compressor to paint a car
Yes that should be fine, you may have to give it a minute to catch up but it probably will keep up just fine
So my question is on my new set up....purchased a 27 gal husky compressor rated at 200 psi, 6.8 CFM@40, 5.1@90. Would like to paint a hood and two fenders off of the car..... the HVLP gun I purchased says average consumption 4.3 CFM, and Operational pressure says 40psi. How do I use this info.
1. What do you think of this, and will I be able to get through a painting job?
2. Trying to decide how to set up the lines. I have two 50foot poly lines, and a water separator and separate regulatory I will instal between the lines. I think I will shorten the first line to 20-ish feet To give the air time to cool and condensate into the filter, correct?
3. So the pressure coming out of compressor should be set to what? Full? The intermediate regulator set to what? And the regulator on the gun set to what? Thanks
So the specs say 6.8@40psi and you gun only uses 4.3@40 so your compressor will have no problem keeping up and you can spray continuously. Pressure will drop with long line length so will have to be set higher at the tank, let’s say 100psi maybe 75 at the midpoint(but this isn’t necessary) and 40 @ the gun to start. If you can’t get 40psi at the gun raise the pressure at the tank. Hope this helps
I'm in a similar situation. If I understand correctly, and to abbreviate your answer, you are saying measure PSI at the gun and maintain 40psi there?
3:28 Is there a way of calculating that 45 second run time using maths?
Boyle's law states that "as the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together. Conversely, as the pressure on a gas decreases, the gas volume increases because the gas particles can now move farther apart." P1V1 = P2V2
Which means that as you start spraying, and the pressure in the tank starts to drop, you gain volume which helps you sustain the spray. It's a dynamic situation which makes the static equation above challenging to apply.
I've been spraying for over 30 yrs and I'm telling you, that little Porter-Cable compressor will not work
I have a California air tools compressor, it's about the size of the one on the floor, maybe a tad smaller. I believe it only puts out 3cfm. Can i get a sprayer that requires around 4.5 cfm if im only using it for small jobs? Like motorcycle parts and stuff?
Could you help me find the cheapest sprayer/compressor??
Forrest Gump: "And that's all I have to say about that."
You just need to raise the volume a little. I cant hear this.
cant hear you
Pretty much no single-phase compressor will keep up continuously with a HVLP spray gun or any sort of decent sand-blaster - they will all lag like crazy, resulting in poor spraying and sand-blasting being a severe drag.
I only have single phase power in the workshop, but I want to sand-blast continuously for long periods of time (with a non mickey-mouse blaster), plus I also want enough air to spray a bus - mainly as we spray quite a few busses.. So, I have a severely "Frankenstein" compressor set-up but it reliably supplies "All the Air" for as long as you want. Plus it was cheap as chips & home-built - which is always good.
Basic "jist" is I have an older, really heavy-duty Japanese 10hp petrol compressor that has its own 200l tank - plus a 3hp single-phase compressor, also with a 200l tank - both feed into an additional 200l tank (off a busted compressor) & I can run either just the petrol, just the electric or both at the same time depending on how much air I need. All 3 200l tanks feed into a big condensor loop that cools & dries the air - which in turn feeds cool, dry air into a 3/4" line that goes to the air-outlet points around the workshop. What you get is 600l of air-storage at 110psi, being fed by either one or 2 compressors depending on how crazy you'd like your air-volume to be - and the end result is NOTHING you'd like to run off air struggles for supply.
Just my 2c. :-)
Sounds like a nice setup, I have a big 10hp 3ph with a 100 gallon tank and an extra 150 gallon tank. Even with that my big sand blaster will use more air, just need to stop now and again to let it catch up.
This wasn’t helpful enough for 7 1/2 minute video. But I did learn some
Speed it up to 2x
Stone Cold says: "WHAT!?"
Raise you audio volume, the compressors are drowning you out
Can hardly hear your voice
Your volume is too low.
Low volume
Hey sir, my volume is at max but still i can not understand what your saying....maybe you need to increase your voice volume pls......
So both of the examples are no-buys for larger jobs
You can do it, you’ll just have to wait while the compressor catches up
Tom, you need more psi for your voice.
😂
Lmao
😂😂 made me laugh
😂😂😂
If you can't hear him, turn on your captions. I can hear him fine, and I have Auditory Processing Disorder. 🤷♀️
WHY ALWAYS PEOPLE BUY HVLP SPRAY GUN?? I JUST DON`T GET IT. LVLP GUN IS SAME GUN AS HVLP, BUT LVLP OR TRANS TECH- AIR CAP. HVLP= HI VOLUME (OF AIR) LOW PRESSURE, (ABOUT 29-35PSI). LVLP= (LOW VOLUME OF AIR REQUIRE) FOR EXAMPLE: DEVILBISS PRO LITE: T110- AIR CAP IS TRAN TECH AIR CAP ABOUT SAME THAN LVLP, AND THE BEST CLEAR AIR CAP EVER!! SAME GUN, HV25 IS HVLP AIR CAP, AND AIR COMSUMPTION IS A WHOLE LOT MORE… DO NOT BUY A HVLP- SPRAY GUNS!! HVLP GUN IS NOT BETTER GUN THAN TRANS TECH OT LVLP SPRAY GUN.
I think the main reason is cost, you can get a cheap HVLP gun for under $50. Is it the best out there obviously not but you can get decent results at an entry level price
Don’t be afraid to speak up for the hearing impaired
Y’all complaining about not being able to hear need to get a better Obama phone or turn up your hearing aid! Sound is just fine.
Thanks, I know it’s not the best audio but I definitely thought it was ok
i dont hear whatyou are saying ,please do something with the audio
Your microphone sucks dude barely hear u. Ugh
Would have loved to hear but couldn’t understand. Sorry, left
