Description

The COBRA single stage, direct driven, dry vacuum pumps, with their unique rotary screws, are designed for difficult applications in the pharmaceutical and chemical processing industries. They require no intercoolers and offer greater efficiency and easier maintenance than other types of vacuum pumps.

Features

Oil-free operation - no disposal costs, easy product recovery, environmentally friendly Simple screw design - fewer parts, easier maintenance Single stage - no intercoolers required Small footprint - for less space requirements Noncontacting parts - for longer pump life Optional purging system - for flushing of toxic and condensable process gas
