NEW 86/87R Series

download brochure Quietly Setting a New Standard
The NEW Gast 86/87R Series oil-less rocking piston compressors and vacuum pumps are quieter, more durable and fit virtually any application. The sleek, new 86/87R Series performs in ways not yet seen in the industry. The patented crossover chamber design regulates and controls airflow to dampen sound and optimize performance, while delivering a wide range of pressure level options.

The inherent design of rocking piston technology makes it the optimal choice for applications requiring high pressure or vacuum and air flow in a small package.  Because the 86/87R Series can easily retrofit into an existing footprint, it’s also a smart, flexible solution for a wide range of markets.

The flexible cup is made with superior materials and mounted on top of the connecting rod, creating vacuum or pressure while maintaining a tight seal against the cylinder walls in a rocking motion. The forgiving design has fewer components, causes less friction and has a low exhaust temperature, for greater reliability and durability for the life of the product. Despite its small size, the versatility of 86/87R means this is the right product to deliver quality air solutions.
