shut off 's ?

[beerthief]

has anyone installed shut off valve's in the air system , one at the compressor and one after the air filter near the fill probe with a pressure release? This would leave the hoses and the filter charged so no depressurizing ? this would be if filling multi guns or gun +tank i would not leave @ pressure in storage .

Wouldn’t you be starting the compressor against pressure? Many compressors are better started with zero pressure.

I see where both of you are coming from, BUT if you already have some pressure in the system, say 4500psi, you hook it up to a tank at 3,000 psi, that high pressure is now reduced and you can start the compressor. Safely???

Nope. You need a check valve at the filter and bleed before filter to start compressor. You need shutoff and bleed after filter to disconnect gun or tank. This way you can fill multiple vessels without waiting to pressurize filters each time.

Exactly, a check valve just after the compressor, and before your main filter, allows for starting and stopping the compressor with no load against the compressor.

Makes perfect sense, thanks.
