New oil-less rocking piston compressors from Gast Group. Quietly setting the new standard

The Gast Group – a leading designer and manufacturer of compressors and vacuum pumps and a member of IDEX Corporation’s health and sciences division – 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 explains, 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.

Summarising, Andre Goodson says the new models enhance Gast Group’s already extensive rocking piston range and help create new opportunities in numerous sectors, for applications as diverse as oxygen concentration, beverage dispense, body fluid analysis, automotive suspension, sterilisers, tyre inflation equipment and core drilling.

Since 1921, Gast Manufacturing, Inc. has been designing and manufacturing quality air-moving products. Our vacuum pumps, compressors, air motors, gear motors, vacuum generators, regenerative blowers and Smart Air technology meet the many challenging applications of OEMs and end-users worldwide. For industrial manufacturing, health care lab, or environmental cleanup applications, Gast provides a full range of ideally suited and cost-effective solutions to any pneumatic problem.

In 1998, Gast was acquired by IDEX Corporation and is part of the IDEX Health Science Technologies segment. IDEX, an acronym for Innovation, Diversity and EXcellence, manufactures proprietary pump products, dispensing equipment, and other engineered products for a variety of global markets.

In 2006, Gast Manufacturing, Inc. acquired JUN-AIR, the leading provider of quiet compressors for laboratories, dental clinics, medical, beverage, graphic and industrial applications worldwide. As a result, its customers can take advantage of the broad product portfolios of both companies to solve their application requirements from the component level through complete compressor solutions.

Since the introduction of its first compressor in 1958, JUN-AIR has become a leading supplier of quiet air compressors used in laboratories, dental clinics, medical, beverage, graphic, and industrial applications worldwide. Its products include a full range of standard and customised compressors and cabinets. Continuous development of products and production facilities helps maintain JUN-AIR’s enviable reputation for quality and reliability among more than half a million satisfied customers.

JUN-AIR products are now sold and supported in more than 100 countries through subsidiaries and distributors. As an international company, JUN-AIR is concerned about the world environment. They strive to produce a range of products that offer environmental benefits such as the reduction of greenhouse gas emissions through reduced energy consumption. Over the years they have introduced a number of improvements, resulting in the most energy-efficient compressors on the market.

Gast is an international supplier with manufacturing and logistical facilities located regionally in support of global customers. They are committed to conforming to global manufacturing standards in the areas of health, safety, environmental, and consumer protection.

Gast is proud of its 90-year history of leadership in the design and manufacture of high-quality air-moving products.
