The COBRA NP dry screw vacuum pumps provide vacuum down to 0.075 torr, pumping speeds up to 180 ACFM, and operation at any pressure from atmosphere down to ultimate pressure. The pumps are direct cooled, but can be supplied with closed loop evaporative cooling. Advantages include: oil-free operation for easy product recovery and no disposal costs; a simple screw design for easy maintenance; single stage design with no intercoolers; a small footprint for less space requirements; non-contacting parts for longer pump life; and a straight, short flow path for quick discharge so product cannot accumulate in the pump.
