A screw air compressor (also known as a rotary screw compressor) is a positive-displacement gas compressor that uses two intermeshing helical rotors—commonly referred to as the male and female rotors—to compress air. Unlike traditional piston compressors that rely on a reciprocating motion, rotary screw compressors use a continuous rotary motion to trap and compress air, delivering a smooth, pulsation-free flow.

Our screw air compressors are engineered with precision-machined screw elements, robust industrial-grade construction, and advanced control systems to deliver reliable, energy-efficient compressed air for a wide range of industrial applications.The self-developed screw rotor with high efficiency and large displacement adopts the self-developed rotor profile, which has a more optimized leakage triangle, shorter contact line and smaller discharge end space than the traditional profile.With precise bearing arrangement to improve rotor rigidity, and optimized oil injecting ratio, Zeding compressors operate with lower noise and less vibration.
