Air Vacuum Pump

The air vacuum pump is a venturi-type AC pump that eliminates moisture from air conditioning systems, which makes it safe and easy to add refrigerant. The atmosphere vacuum pump is simple to function and pulls complete vacuum within two moments of being connected to an air range. Contains 1/2 in. ACME (R134a) and R12 connectors.

Air-powered vacuum pumps work when compressed air passing through an orifice increases its velocity and lowers its air pressure. Ambient atmosphere is used through stations in the generator, creating suction and vacuum. The atmosphere stream exits through the exhaust. … These operations require vacuum pumps.
