Gast rocking piston compressor

Gast's rocking piston compressors and vacuum pumps are oil-free and maintenance-free. In a reciprocating motion, a flexible cup on top of the connecting rod seals against the cylinder wall in a rocking movement, creating pressure or vacuum. The series covers air flows up to 12 cfm, pressure up to 175 psi (12 bar) and vacuum up to 29.5 inHg. The units are light, robust and corrosion-resistant, and run quietly.

The 86R and 87R models are designed for flexibility, quiet operation and optimum performance, and deliver higher pressure at a significantly lower sound level. Both have been redesigned for lower exhaust temperature and have an extended service life. The 106R is one of the most versatile models in the series, with an “all-world” motor for 120/230 V, and can be used both as a compressor and as a vacuum pump. The 86R, 87R, 106R and 120R can be supplied with Sound Shield, which reduces the sound level by up to 25% dB(A) and perceived loudness by up to 40% sone.

The motors are dual-frequency, and Sound Shield models are available. Typical applications are dental compressors, eye surgery equipment, ventilation equipment, surgical suction, nitrogen generators, laboratory equipment, dry sprinkler systems, beverage dispensers, cable pressurisation, vacuum mixing and oxygen concentrators.
