Screw blowers compress air using two interlocking helical rotors. As the rotors turn, air is drawn in, trapped between the rotor lobes and the casing, and pushed forward. The volume shrinks as the air moves, increasing pressure before it exits the discharge port. This continuous, rotary motion delivers a steady stream of compressed air with minimal pulsation.
Key Components
- Male and Female Rotors: These rotate in opposite directions. The male rotor typically drives the female.
- Housing: Encases the rotors and defines the compression chamber.
- Inlet and Outlet Ports: Control airflow direction and pressure.
- Timing Gears: Keep rotors synchronized without contact, reducing wear.
