Cooler used for cooling compressed air and oil. With excellent reliability, little vibration, low noise, easy to operate, the vulnerability of small, high efficiency is its biggest advantage. Screw compressor is one of the volumetric compressor, air is compressed by device in parallel to each other in the cabinet of the Yin and Yang of the rotor meshing gears slots volume change and achieve. The rotor in and it precision with vice of the shell and the roll inside make rotor slot of the gas between the teeth are created the volume of periodic changes along the axis of the rotor, inhaled side by side to eduction, complete inhaled, compression, exhaust three working process.
