Rotary Vane Vacuum Pump, 2.8 CFM, 115V 60 Hz

Consumes less oil by cool running operation|Large oil capacity minimizes rates of oil breakdown Chemical-resistant coating in oil case and pump module protects non-moving parts Up to 50 dB (A) noise level for undisturbed work IP54 enclosure rating|Flow rate of 2.8 CFM (79 l/min)|Runs on 115 VAC power|The CRVpro series two-stage, direct-drive rotary vane vacuum pumps offer a unique airflow design allowing them to run 10C cooler than standard rotary vane pumps, leading to reduced chemical activity within the pump and less oil consumptionup 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.
