New Oil-Less Rocking Piston Compressors

The Gast Group has launched two completely re-engineered oil-less rocking piston compressors and vacuum pumps which, the company claims, are quieter, more durable and suitable for virtually any application. 

The new 86/87R Series extends the company’s already impressive range of rocking pistons and features a new design with a patented crossover chamber design. This causes air to decelerate as it enters the crossover and accelerate as it exits, which dampens the sound and optimises performance while delivering a wide range of pressure level options. The result is a rocking piston that reduces noise output by over 5 decibels compared to previous models and delivers higher pressures, a longer life and greater application flexibility.

As Gast Group’s European Sales Director Andre Goodson explained, when the company set out to re-engineer its rocking piston compressor it aimed to do more than just increase pressure. “We set out to dramatically reduce sound, enhance flow, improve the compressor’s aesthetics and create a standard footprint for easy retrofit anywhere in the world.”

As a result of this re-engineering, the 86/87R Series features universal dual voltage motors for worldwide operation and its design and construction contains fewer components, causes less friction and has a low exhaust temperature for greater reliability and durability throughout the life of the product. For OEMs, the new single- and twin-cylinder 86/87R Series features common port locations, additional side ports and can easily retrofit into existing footprints, making it a smart and flexible solution for medical, laboratory, printing, material handling, transportation, food and beverage, environmental and general industrial applications.

Despite its compact size, the 86/87R can reach a maximum pressure of 8.6 bar (125 PSIG) as standard, with the single-cylinder version providing up to 65 lpm (2.3 SCFM) maximum airflow, and the twin-cylinder providing 150 lpm (5.3 SCFM). Vacuum pump versions are designed for operation down to -930 mbar and bespoke compressor models are available on request.
