Contact information of oil-free air compressor manufacturers

Oil-free air compressor manufacturer contact:

at present, the main brands of domestic oil-free air compressors are: Granklin and so on.

the principle of oil free air compressor:

when the motor runs, the air enters the compressor through the air filter. The compressor compresses the air. The compressed gas opens the one-way valve through the air flow pipe and enters the air storage tank. The pointer of the pressure gauge rises to 8 Bar.

When it is greater than 8 Bar, the pressure switch will automatically close after sensing the channel pressure, and the motor will stop working. At the same time, the solenoid valve will discharge the air pressure in the compressor head to 0.

At this time, the air switch pressure indicates that the gas pressure in the gas tank is still 8 Bar, and the gas is driven by the ball valve exhaust to work.

When the air pressure in the air tank drops to 5 Bar, the pressure switch is automatically turned on by induction, and the compressor starts to work again.
