I have an air industrial developments compressor and wanted to understand a bit more about how it works
There is an obvious pressure relief valve that has a narrow windy copper tube that runs up to the inlet side of the compressor pump and I have assumed that this is meant to help it restart under pressure by somehow balancing the pressure across the pump
It didn't have any control gear when I got it so I have fitted a standard automatic pressure cut off switch but I haven't hooked it up to an unloader valve
It starts and initially restarts when the pressure drops but when it is worked hard it sometimes goes to restart and stalls humming loudly. Switching off and on again several times gets it running again so I think the motor and capacitor are ok
Do I just need to be kinder to an old compressor or should I fit an additional unloader valve and plumb it to the pressure switch?
