Some small compressors can fail to start up if powered by a small generator because of the pressure that is retained in the pipe to the receiver. This results in the piston being presented with the high pressure that is still in the receiver when the low pressure limit is reached.

What they need is an air compressor unloader valve.

The output of the piston compressor is connected through a pipe to the air receiver. When the compressor stops, the pressure in this pipe is blown off to 0 bar (atmosphere).

This is the ssssssshhh sound you will here when the compressor stops. At the same time, a check-valve makes sure that not the whole air receiver (tank) flows empty, but only this small pipe.

Why? When the compressor starts up again, and this pipe would still be under pressure, the electro motor will not be strong enough to turn the compressor.

You can fit post fit an unloader valve.
