This is my air compressor I have rebuilt. The only difference to how it is running now and how it runs here is I have added an electric solenoid to operate the decompresser instead of using the oil pressure. The motor is 4HP 3-phase 1400 rpm run via a single to 3-phase inverter at 25 Hz (1/2 speed). The compressor fills all 3 air tanks reasonably quickly.
Is that a question? Am I meant to know the answer?
