Direct Driven Vacuum Pump

Listing ID #3711937

To improve the backing pressure and displacement at low pressure two stages are connected in series. If the Power Supply fails on stops, an anti-suck back device. Prevents air or oil the pump to be drawn back into the chamber being evacuated and operated by Solenoid coil. The gas ballast allows a quantity of air to be injected into the second stage of the pump during compression to reduce the partial pressure to the pumped gas below its saturated Vapour pressure and thus prevent condensation.
