DIY - extinguisher to compressed air tank conversion - no welding
Vložit
- čas přidán 6. 06. 2020
- I wanted to make small portable compressed air tank which can be charged and used to fill bicycle tyres, party balloons or water rocket.
The plan is to use it with silent compressor taken out from broken fridge. - Věda a technologie
This video saved me hours of research and that's why I subscribed.
Thanks.
Those are probbaly the hours I spent looking for the thread type.
That's neat! I'll try this. Thank You!!
No problem. Thank you for your comment.

Good job!
Thank you.
Have the compressor the empty fire extinguisher some of the fittings just need to get my arse in gear and make now that lockdown in here again and have taken up model building again. TFS, G :)
Thanks for your comment. The little tank should be ok for something like air-brush. I built air compressor from fridge compressor but this thing still spitting the oil with compressed air. Not very good for painting.

Good work
Thank you so much 😀
Harika zuper super oldu
Thank you.
일단 용접하지 않고 할수 있는거에 ^^b 저도 필요없는 정수기에서 하나 꺼내왔는데 소화기 하나 구해봐야겠네요...
That was done without welding. To empty moisture from inside simply keep the tank up-side down when removing the air. Google translation was not very clear so I do not understand but thanks for the comment.

Yup good👍
Thank you.
Very good technique 👍
Can I use this for spray painting
Hi,
I have no idea if this works for spray painting.
My plan is to use it for blowing the dust off when working on car and fill the tyres when needed without dragging the whole compressor with me.
If you try it please let me know if it works.
Good luck and best regards
for airbrush only...
How is your tank , how many tires could you fill with one tank want to use for off road
Hi,
All depends on the tyre size but the answer will unfortunately disappoint you...I think with this tank you will feel 0 (zero) tyres.
The tank is about 2lit of volume. If the air is compressed x8, to 8bar it means that there was pumped (2x8) 16lit of air inside the tank. This will give you only 8lit of pressure at 2bar.
All of that is govern by science and Boyle's law p1V1=p2V2.
I saw somewhere on youtube similar tank was used to pop in the tyre on the rim but it was using 1/2" valve and bigger nozzle.
You would need bigger tank or tank rated for higher pressure for ex. CO2 extinguisher, which are rated to much higher pressures and you would have to be able to compress the air to this pressure. In home conditions that would be extremely challenging and dangerous.
Be careful and good luck.
Hi; Great video! Is the check valve necessary?
I would say "yes" otherwise the air will keep comming back and will prevent air blowing back if the hose breaks.
Try to remove the valve from bicycle tyre and pump it up. This will maybe give you better idea.
Thanks for your comment.
Buenos diass, de México. Saludsss,.
Thank you. All the best.
I wanted to see you use it
Hi,
Thanks for the comment.
It has very small volume so the use is also limited. I'm using it to blow some dust off when working on the car. Now I'm planning to use it for sand blasting.
Best regards

Me too I will build one this is really cool :-)
Thanks.
Can I use any other valve instead of 10 bar pressure relief valve..??
Hi,
You can use what ever suits your design. The valve is there to prevent accidental overpressure.

Can you please name the tools used in making the air tank
It's been ages since I mead video but I think I used standard adjustable spanner and maybe "French wrench - adjustable".

the thing you screw down in fire extinguisher what is it called
7/8 unf to 1/2 bspp male adapter?
Hi,
Yes, it is male adapter.
Shed Made In thanks alot
I want to run a bike...which kind of tank is suitable for that...and what is my min. Pressure to achieve 60 kmh speed....
Hi,
I have no idea, out of me depths here. It sounds dangerous so whatever you do be careful.

SMI
meron po b ma order sa inyo ng adaptor pra din sa fire extinguisher ung set n po
Wauu👍
Thank you.
and an example of usage? I mean filled to 8bar, how much is it usable?
Hi,
It all depends... This is small tank 2l volume. The applications will be limited. Forget about using it for big compressor.
I personally used it to pressurise brakeing system of my car during brake bleeding.
I also was thinking to use it as a compensating tank for central heating system.
Thanks for your comment.

Using a tankless Airbrush compressor - I am thinking the safety relief valve is not necessary ? The compressor regulates pressure ....
Hi,
I'm using various equipment to charage this tank and wnat to have a safety valve mounted just for piece of mind.
This will also prevent pressure from rising if charged tank is left in sunny place.
It's up to you to assess your system and decide if you need or do not need additional safety valve. Is it really worth it to skip this safety feature for what you need to pay for the valve?
Thanks for your comment
Best regards

So, how much air will this tank hold?
Not much :).
The tank is 2l...The storage volume for a compressed gas can be calculated by using Boyle's Law
p1xV1=p2xV2
V1=(p2xV2)/p1
The final volume depends on how much are you able to compress the air. The tank I think is rated for higher pressure but standard compressors will provide around 8bar. That means that you can squeeze in about 16l of air.
I'm using the tank mainly when bleeding brakes.

Does this work with medical oxygen tanks as well?
Hi,
You can fill any tank, I think, with compressed air as long as it has got suitable pressure rating.
Compressed air can be dangerous so stay safe and do some research before playing with it.

Could a fridge motor be used to fill it
Hi,
Thanks for the comment.
Fridge compressor is what I'm planning to use with it. I started to built compressor side but do not have enough time to finish it.
Be careful with fridge compressor those are rated to 8bar, so probably can go much higher.

@@shedmadein4115 Great thank you for the reply I hope u get ur fully up and running going to start mine soon
Bhai hamare pass 5 kg Bala fire cylinder hai usmein Hawa Bhar sakte hain fatega To Nahin
If you are repourposing any kind of tank to store pressure make sure it has got correct pressure rating and it is sound.
Anyway never fully trust it and always remeber you have one life to live. Stay safe.

damn seems like an awful lot of work to make a portable air tank must be an easier way. i didnt use this many fittings when i converted a 47kg gas bottle and i did use valves and a gauge and a filter system!
use original extinguisher handle with holes drilled in it so the safety pin can be used to keep the handle down at varying degrees of pressure
Hi,
Make a video and add upload.
I guess there are more than one way to achieve same similar result.
Best regards
SMI
Good idea. Thanks.
@@shedmadein4115 i made a much simpler version a 9 litre water fire extinguisher cut the end off the hose and fitted a barb fitting that goes into the hose and clamp on it to hold it then the other end was a quick connect so then i just connect it to my compressor hold down the trigger on the extinguisher until the pressure equalises and job done! super simple!
refilling fire extinguishers with air pressure you usually unscrew the hose and screw in an adaptor with a tyre valve on the other end then you just pressure it up the same way as i do it.
so the method i used is pretty safe the only extra thing involved is the hose which has walls that are thicker than my airline hose. Its supposed to take far more pressure than my compressor could supply anyway so im pretty confident its safe enough with only 8 bar of pressure max. the extinguisher can take upto 12 bar.
how many psi can save at the tank
I belive this tank is suitable for 13.5bar which is around 195psi. Check the tank you are going to use it should have a working pressure stamp on it.
Best regards

@@shedmadein4115 thanks for that info
Make a shopping list please
It's a good idea.
Thanks.

Dang. I tried every fitting in the world and it will not screw on my fire extinguisher tank...So what now? I may need assistance. Might I add it's not the same tank.
Hi,
I spent ages resarching threads on this extinguisher.
Measure the thread size and try to search online. There is wide variety of threads types used for those tanks.
Sorry that I can not be any more of a help here.
Best regards
SMI
@@shedmadein4115 much appreciated.
Just bring the tank to the hardware store and match lol
Bro can you tell me the components name please
Hi,
I can not remeber what I have exactly used but 1/2" and 1/4" tees and nipples. If you have choice use the ones with NPT thread rather than BSPP.
I think most if not all components name are given during the video.
Best regards
SMI
Thanks 😊
Menuda música de fondo
ok. Thanks :)
Thats about 100$ in fittings.
Hi,
I think it is project for kind scrap unused fittings rather than buying new fittings fromlocal hardware store.
Possible that you may find complete compressor cheaper than all the fittings.
Thanks for the comment and best regards

San nabbili ung materials nyan?
There is no parts list. I described parts in the video.
Thanks for your comment.
SMI
can we fill liquid oxygen in it and use it as oxygen cylinders ??
Hi,
Pass on this one. i would not use it for anything else than compressed air. Liquid oxygen seems dangerous and high pressure.
Oxygen turns into liquid above 49bar so why to high for this tank anyway.
Do the reasearch before trying out things...
Best regards

San bbli ng materials nyaa?
Hi,
I tried to translate your question to english but with poor results...
"Where did the materials go?"
Sorry but I do not know what you mean.
Best regards
SMI
There is no list of materials, the parts are named during video if this is what you mean.
just kill the music its horrible
the instructions and assembly were good
Thanks. It takes a lot of time to make video and select music. I restricted my choice to probably 3 diffrent tunes. Volume control is your rescue ;)
I didn't even watch the video, the music was SO GOOD I just cranked it up and minimized the window.
SERIOUSLY??? You could buy a 3-4 gallon tank for less than the cost of those parts.
Why do creators make a decent video then overlay some unbearable audio track. 👎👎
I have no idea .... :)
Thanks for comment.
