Question on small air compressors with storage tanks (for example - 10 gallons)?

Question

Does the machine use the air in the storage tank first, and when that runs out, still provide the desired line pressure as the compressor kicks in?

Or once you use the tank supply, do you have to wait until the tank is repressurized?

I am redoing the sprinkler system in my yard, and instead of installing a multitude of drain valves, I would like to just blow the lines dry before winter with pressurized air, if possible.

Any comments or suggestions on tank size, or brand, would be appreciated if you have any experience in this area.

Thanks!

Answer 1

It really depends on the length & diameter of the lines. My suggestion would be to put a flow valve in the line so that the pressurized air can only flow one way. That way if you had to wait for the pressure to rebuild the air already added to the system won't escape. An in-line valve can be purchased at any automotive paint supply. A simple shut off vavle Installed in-line will work just as well.

Answer 2

Yes you can convert it, however it is designed to compress a refrigerant, not air. This makes it inefficient as well as slow. Also, you have to remove the refrigerant at a collection site. The amount of money this would cost you would be a lot more than it would to visit your home repair store and buy an air compressor with an eight gallon tank with all the fittings and hoses included.

Answer 3

air compressor is set at a pressure and when the tank gets to below that point it turns on to rebuild the tank air.didnt know you had to drain water sprinklers all the way.as long as the line is'nt full of water and water is off they shouldnt freeze and break.
