Screw Blower

A screw blower is a positive displacement blower that utilizes a pair of precisely meshed male and female rotors (screws) rotating within a housing to compress and transport gas. Its working principle involves the continuous movement and displacement of trapped air pockets from the inlet to the outlet without internal compression, generating a pulsation-free airflow. Compared to traditional Roots blowers, it operates more smoothly with significantly reduced noise and vibration, offers higher energy efficiency, and also delivers oil-free air. It is an ideal, energy-efficient choice for applications such as wastewater treatment aeration, food processing, textile printing and dyeing, and pneumatic conveying.
