air vacuum pump
The air vacuum pump is a venturi-type AC pump that eliminates moisture from air conditioning systems, making it safe and easy to add refrigerant. The air vacuum pump is easy to operate and pulls full vacuum within two minutes of being connected to an air line. Includes 1/2 in. ACME (R134a) and R12 connectors.
Air-driven vacuum pumps work when compressed air passing through an orifice increases its velocity and lowers its air pressure. Ambient air is drawn in through channels in the generator, creating suction and vacuum. The air stream exits through the exhaust. ... These operations require vacuum pumps.
Adjustable-Flow Air-Powered Vacuum Pumps
Use the rotating diffuser to alter flow rate. Also known as venturi pumps, these compressed-air-powered pumps are commonly used in vacuum packaging, pick-and-place operations, and end-of-arm robotic tooling. They have no seals or moving parts that can wear down or overheat, and they don’t require lubrication, so there's no downtime for maintenance. The compact body allows inline installation close to your vacuum point. Maximum flow rate is the rate at which air is pumped before a vacuum is created. Flow rate steadily decreases as the pump generates the vacuum. The larger the tank, the longer it will take to form a vacuum. Tube and fitting ID will also affect flow.
