Dry Screw Vacuum Pumps
Dry screw vacuum pumps operate with two screw rotors rotating in opposite directions. This traps the medium to be pumped between the cylinder and the screw chambers and transports it to the gas discharge. The advanced screw design results in lower electric energy consumption compared to standard screw designs. It also results in a lower heat load of the compressed gas. IVS sells and repairs Dry screw vacuum pumps from Kinney, Leybold and Pfeiffer.
