It adopts an eccentric rotor + vane structure.
As the rotor rotates, centrifugal force pushes the vanes against the inner wall of the pump chamber, cyclically completing the process of suction — compression — exhaust.
The oil film simultaneously provides sealing, lubrication, and cooling functions.
The built-in oil mist separator + anti-return oil valve prevents oil backflow during shutdown and ensures clean exhaust.
Time-tested rotary vane technology, powerful and durable.
