QOWI 20-75V

QOWI is an oil-free air compressor, which USES water spray twin-screw and variable frequency drive technology.The bearing of compressor rotor is lubricated by water to avoid oil entering the compression chamber, and the compressed air is 100% oil-free.During the compression process, due to the cooling effect of water spraying, the air temperature rise only increases by 25°C, which is very close to isothermal compression, and the maximum pressure can reach 13bar.
