The screw element was first developed in 1930s, it has a male and female rotors, the male rotor drives the female rotor if it’s an oil injected screw compressor technology; and a timing gear drive both rotors in the oil free compressor technology as both rotors will run harmonically with minimum calculated clearance between both elements.
The basic principle of a screw compressor is as the male and female rotors are rotating in opposite direction, they draw air in between them. As the air progresses along the rotors the air is compressed as the volume space between the rotors decreases, hence creating compressed air that is displace to the outlet. The speed of the rotors is optimized at a certain level to minimize mechanical loses (due to heat at very high speed) and volumetric losses (air losses due to very low speed).
