Why use a Linear Product? Reliable The moving parts consist of an actuating rod supported by two special synthetic rubber diaphragms. They oscillate laterally, permitting a minimum of 30,000 hours of continuous operation on many models. Other than the occasional filter cleaning, operation is virtually maintenance-free. Replacement parts come in a cassette. Quiet Sound insulation was a prime con­ ideration in the design of the pneumatic circuit and mechanical section. s The result: a surprisingly low operating noise level – as low as 38 dB(a). Energy Efficient Operation is based upon the...

Linear Performance Overview *Shown here are performance ranges of our positive displacement models. Note: Performance shown on inside charts is for continuous operation. Higher performance is possible on an intermittent basis (10 min. on/10 min. off) for some of the models listed. Consult Factory. 4 Gast Linear Compressors and Vacuum Pumps

Typical Applications Environmental Applications Tank aeration Fish or lobster tanks located in pet stores, restaurants, or supermarkets require air to keep their contents alive. Tank location and size will dictate the type of compressor to be used. Pond aeration Pond aeration is done for two basic reasons. One is aquaculture, where large numbers of fish are “farmed” in a single pond. The second is ecological. As a pond or lake ages, it can lose its oxygen supply and may die. When air is introduced into a pond or lake, oxygen becomes plentiful again and life in and around the water can...
