Gast Rotary Vane Aerator Pumps

GAST OILESS ROTARY VANE PUMPS AND COMPRESSORS

The Gast Rotary Vane units offer oil-less operation to ensure the discharge air remains free of contamination from lubricants. The Gast compressors offer high flow, pulse free air which makes them ideal for applications requiring consistent air pressure and flow.

HOW DOES A GAST ROTARY VANE PUMP WORK?

Pumping action is produced by a series of sliding, flat vanes as they rotate in a cylindrical housing.An eccentrically mounted rotor turns and the individual vanes slide in and out of their slots by centrifugal and pressure-loading forces. This creates a series of air compartments of unequal volume against the wall of the housing. These compartments get larger during the suction part of the cycle, creating vacuum at the intake port and smaller during the discharge portion of the cycle, creating pressure at the exhaust port. The vacuum and pressure flows are free of pulsation because the inlet and exhaust ports do not have valves, and the air is moved continuously rather than intermittently.

WHY USE A GAST ROTARY VANE AIR PUMP?

Gast Rotary Vane vacuum pumps and compressors have certain significant advantages. In addition to providing smooth, pulse-free air flow without receiver tanks, they are compact (or equivalently offer high flow capacities for a given size), are simple and economical to install and operate, have low starting and running torque requirements, produce minimal noise or vibrations, are capable of long, service-free life, and are easily serviced.

If these features are what you need in your pneumatic application, a Gast Rotary Vane model can provide you the right solution.
