What is the working principle of screw air compressor？

      The main and auxiliary rotors of atlas air compressor rotate in the precisely matched casing, so that the gas between the rotor teeth and slots continuously produces periodic volume changes, and pushes it from the suction side to the discharge side along the rotor axis to complete the working processes of suction, closed transportation, compression, exhaust and so on. Screw air compressor is a positive displacement compressor. Air compression is achieved through the volume change between the male and female rotor teeth installed in the shell and meshed in parallel with each other.
