COBRA N singlestage direct-driven rotary-screw dry vacuum pumps
The COBRA N singlestage direct-driven rotary-screw dry vacuum pumps incorporate a monoblock, continuously variablepitch screw design, which allows them to operate more efficiently and provides a higher cfm-to-horsepower ratio than traditional dry screw vacuum pumps. They provide vacuum down to 0.0074 torr and pumping speeds up to 225 actual ft3/min. Direct-cooled and closed-loop air-cooling models are available.

Panther PD blower
The Panther PD blower is a rotary-lobe, positive-displacement blower that is designed for either pressure or vacuum applications. Vacuum or pressure is produced by two non-contacting rotors in an oil-free pumping chamber, creating a clean, efficient and wear-free environment. The Panther blower features a tri-lobe design that increases efficiency and decreases sound levels. Heavy-duty construction and oil-lubricated bearings on both the gear end and drive end of the blower ensure reliable operation.
