Description
COBRA N are high efficiency dry screw vacuum pumps suitable for many industrial applications as well as chemical and pharmaceutical processes. As no contact between screws and cylinders takes place and no sealing fluids are needed, COBRA N vacuum pumps can convey vapours and liquids without contamination. The many options available for cooling, sealing or coating makes the COBRA N suitable for almost any application or process.

Due to its revolutionary one-piece screw rotors with variable pitch, the "B" series COBRA N pumps provide vacuum down to 0.0075 torr and pumping speeds up to 241 CFM.
