BOC Edwards EH-1200 Blower Vacuum Booster Pump

This Vacuum Pump is unique in utilizing a hydrokinetic fluid coupling to connect the electric motor shaft to the lobe rotor. The EH mechanical booster pump, based on the simple Roots principle, remain the favorite pump for applications where high pumping speeds are required in the pressures in the region of 0.01 to 10 mbar. This pump must always be backed by another pump backing pump makes it highly reliable.
