Air from the intake pipe into the compressor, the rotation of the motor, so that the piston movement back and forth, the air compression, Make the pressure gas from the air outlet through the high pressure hose open the one-way valve into the gas storage tank, the pressure gauge pointer display will rise to 8BAR, more than 8BAR, the pressure switch automatically closed, the motor stops working, at the same time, the solenoid valve through the pressure relief pipe, reduce the pressure in the compressor head to 0. At this time, the air switch pressure and the gas pressure in the gas storage tank are still 8KG, and the gas is discharged through The Filter pressure regulating valve and the exhaust switch. When the air pressure in the air storage tank drops to 5kg, the pressure switch automatically opens and the compressor starts working again.
