The Gast Group launches its latest series of oil-less rocking piston compressors and vacuum pumps

29 April, 2014

Gast Group offers extensive knowledge of compressed air applications in the laboratory, medical and analytical markets due to its relationships with a wide number of OEMs and its partnerships with equipment distributors. The new models cover multiple applications in sample management, in-vitro diagnostics and numerous analytical instruments, from material and surface science to spectrometry, chromatography, microscopy and other general lab air requirements.

Gast Group has a worldwide presence, enabling it to offer a global support for its compressors; including its latest completely re-engineered 86/87R Series, which the company claims to be quieter, more durable and suitable for virtually any laboratory application. In addition, the new compressor can even be combined to create Jun-Air complete compressor systems with 4 litre or 25 litre receiver tanks.

Patented crossover chamber design

The 86/87R extends the company’s already extensive range of rocking pistons and features a patented crossover chamber design, which causes air to decelerate as it enters the crossover and accelerate as it exits. This 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 dB compared to previous models and delivers higher pressures and a longer life. In addition, thanks to its all-world motor, the 86/87R provides greater application flexibility.

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.

New opportunities

Gast Group’s European sales director Andre Goodson commented that the new models enhance the company’s rocking piston range and help create new opportunities for applications such as oxygen concentration, body fluid analysis, sterilisers, etc.

Other Gast Group products on show at Analytica include its Jun-Air oil-less and oil-lubricated range of clean and quiet compressed air solutions for zero-air and nitrogen generation, and multiple laboratory applications including automation.
