Welch HVAC Vacuum Pumps are used to remove gas, vapors, and other contaminants from refrigeration systems after refrigerant recovery and repair of cooling systems. To ensure the Air Conditioning system is free from contaminants before recharging it with refrigerant, one must maintain a deep and complete vacuum.Our industrial duty HVAC pumps are engineered to deliver deep vacuum for fast evacuation and dehydration. They can pump down quickly reaching 40 microns in hours; not days or weeks like you might experience with a light duty pump.

Welch refrigeration and vacuum pump for HVAC come in two pump styles. DuoSeal® belt-drive vacuum pumps are proven performers with low RPMs and a long service life. Our CRVpro direct-driven vacuum pumps are portable and powerful.

CRVpro models of rotary vane vacuum pumps are portable but powerful and come with forced oil lubrication and a protective coating against the corrosive effects of chemicals on key internal parts. CRVpro pumps are used where high flow is required, and a lightweight and small footprint is desired for service applications such as rooftop HVAC equipment and RTUs.
