Rotary Vane Vacuum Pump

Rotary vane pumps are traditional vacuum pumps, which can be used in a wide area including research and production. The WH series rotary vane pumps are ChemVak's standard vacuum pumps, which can be used individually or as a backing pump in combination with molecular pumps or diffusion pumps in order to create an extremely high vacuum. They are widely used in vacuum distillation, vacuum filtration, vacuum testing, vacuum freeze drying, vacuum plating, leak detection, vacuum packaging, vacuum sorption, and the like.
