Gast rotary vane compressors and vacuum pumps

Gast's rotary vane compressors and vacuum pumps are available as oil-lubricated and oil-free models, both motor-mounted and with a separate motor (separate drive). Flat, sliding vanes in an eccentrically mounted rotor are flung outwards against the wall of the pump housing, creating pressure and vacuum. The result is pulse-free air delivery with low vibration and a long, maintenance-free service life, and the range includes an extra-quiet AT series. The range covers air flows up to 55 cfm (93.5 m³/h), pressure up to 15 psig (1.0 bar) and vacuum up to 28 inHg (65 mbar).

The motor-mounted models in Gast's product overview for 2026 are 0523, 0532, 0823, 1023, 1423 and AT05. The models with a separate motor are 1550, 1065–2565, 2067–2567, 3040 and 6066. 1550 and 3040 are pulley-driven and suit applications where the speed needs to be variable. The largest, 3040 and 6066, are 2 and 5 hp respectively, with air flows of 40 and 55 cfm at 60 Hz.

The electric motors are dual-frequency and supplied in a multi-voltage AC version for worldwide use (AT05 is only specified for 115 V and 60 Hz), and some models are designed for 12 and 24 V DC. Typical applications are breathing air, circulation therapy, packaging, the graphic arts industry, aeration of ponds and sewage, vacuum hold-down, air sampling, office and business machines, food equipment, laboratory use, soil remediation, vacuum forming and air bearings. A complete range of accessories is available.
