I have an old Ingersoll-Rand single phase compressor without a reservoir.
Model WB100, 240V, 4.3 A (Perhaps 1/2 HP).
I am using it with a short air line to pressurize a model locomotive boiler to 20 psi for an initial appraisal of boiler condition.
I can only get about 10 psi because of either boiler leaks or compressor problems.
When I turn off the compressor to listen for air leaks from the boiler (more likely various valves and cocks), I can hear the compressor venting the line internally, and the boiler, down very quickly.
Is output line venting when turned off normal for compressors of this type ?
The output appears to be 1/4" NPT, any suggestions on where to get a non-return valve ?
I have available a small (say 5 litre) high-pressure personal oxygen cylinder that is no longer required.
Is it advisable to use this as a reservoir for the compressor ?
