Description
Overview

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.

DuoSeal rotary vane vacuum pumps are proven performers with low pump RPM to ensure long service life with durable precision machined steel rotor, cast iron intake, exhaust ring and metal vanes. DuoSeal models are used on the most demanding service applications such as purge pump on absorption chillers and Industrial/commercial chillers. Welch DuoSeal pumps are fitted with components designed to withstand refrigerant contact. Models 1402B-46 and 1397B-46 include integrated handles.
