GNS Dry Screw Vacuum Pumps are highly efficient, and ideally suited to industrial applications which require reliable and contaminant-free extraction of gases and vapors.

The vacuum in dry screw pumps is created through two parallel-arranged screw rotors that rotate in opposite directions. These rotors trap the gas coming in through the inlet and deliver it to the gas discharge or pressure side. As the gas is getting compressed, there is no contact between the rotors.
