hi there i recently am interested in making a silent compressor using a fridge compressor, and i currently have a air tank with a tire inflator, but i find it a real hassle turning on my car and inflating the tank with a noisy compressor.
but in both webpages it says that you should drill an extra hole in the middle or in the bottom for air input. i was just wondering it is possible to not drill any holes and to use a non-return valve followed by a T brass fitting connector such as follows:
in my mind i was thinking about that setup but is there an advantage over the second hole? Also does anyone know of more detailed websites reguarding compressor’s made from propane tanks?
I wouldn’t recommend drilling any holes in an air tank as the potential for bursting is increased if there are any defects from the hole you made.
Actually it is best to have 5 holes in a tank: Inlet, outlet, tank pressure gauge, draincock, and safety pop-off valve.
I don’t know if that idea will work anyhow as the T-fitting cannot be taking air in and putting air out at the same time from the same hole can it?
Why not buy a small air tank made for 4x4 trucks and use that?
That is what I did with the compressor I made from a 1/2 hp Jun-Air silent compressor.
This is the 5-gallon one I used for my setup:
hey mike thanks for the reply, i was thinking that if the air is getting pumped into any hole the air pressure would stabilze very quickly and so that you wouldn’t need a second hole for an air input. And yes, your right that you would need more holes for additional meters and guages, i was trying going to add those with t connectors. Another reason for using these t connectors instead of that air tank you suggested is because i was thinking of using a portable propane tank as storage (the ones for torches) i want to use this because i only do very minimal work (1 hour or less) per week on my models and i was thinking of using a 30-50 psi pressure switch and work with low pressure. And since the propane tank is so small it can fill up really quickly and i was not going to use a relief valve because i would be release the pressure off every session i take. here is a rough sketch of what i was thinking:
I am guessing that it would work but I don’t know how well it would cycle in comparison to having an inlet and an outlet for air.
I would give Coast Airbrush a call and ask Dave about your setup.
He could tell you better than I.
