Roots Vacuum Pumps• PVR Industrial Vacuum Pump
GMa 11.3 HV/BP - 13.8 HV/BP
Vacuum blower HV/BP series have been designed for conveying air and neutral gases and are especially used in industrial high vacuum technology.
The integrated mechanical bypass allows the root pump to be started simultaneously with the lubricated vane pump.
The flanged electric motor is connected by means of an elastic coupling.
The following accessories are useful for the installation and for the control of the pump operation parameters:
-
Inverter
-
External suction filter
-
Silencer in line
