MODEL: VS300A-W

Oil Rotary Vacuum Pump

VS300A-W is classified as a rotary vane type Oil Rotary Vacuum pump. Smallest footprint in the class and allows the direct mounting of Mechanical booster pump. In addition, stable exhaust performance is obtained by the Oil mist separator and Oil return mechanism which is build-in into the pump. In addition, it is designed with an easy maintainability for oil and element filter exchanges.
