All basic knowledge of screw air compressor The full name of the air compressor is an air compressor; a machine designed according to the working principle of the rotation of the twin screw (also called Yin and Yang rotor) to change the volume of the gas, it can suck in natural air and then complete the work through several internal processes. To discharge compressed air that meets pressure requirements, this machine is called a screw air compressor.
