More About this Item

The CRVpro series two-stage, direct-drive rotary vane vacuum pumps offer a unique airflow design allowing them to run 10°C cooler than standard rotary vane pumps, leading to reduced chemical activity within the pump and less oil consumption—up to 36% less than comparable pumps. The oil-sealed pumps feature a gas ballast, forced oil lubrication, anti-suck back valve, low noise level, and thermal overload protection. The gas ballast uses either outside air or dry inert gas to reduce condensable vapors from entering the pump oil.
Ideal for use in freeze drying, degassing, vacuum ovens, and concentrators.
