Starting in 1946, Ajax gas engines became a primary product utilized by oil and gas companies. In 1958, the first Ajax integral engine / compressor was manufactured and was specifically designed for field gas gathering applications. It was a DPC 230 and was soon followed by a complete line of Ajax integral engine-compressors from 30-360 horsepower.
Axi-symmetric stall, more commonly known as compressor surge; or pressure surge, is a complete breakdown in compression resulting in a reversal of flow and the violent expulsion of previously compressed air out through the engine intake, due to the compressor's inability to continue working against the already-compressed air behind it.

Diesel engines or petrol engines are suitable for portable compressors and support compressors. In automobiles and other types of vehicles (including piston-powered airplanes, boats, trucks, etc.), diesel or gasoline engine's power output can be increased by compressing the intake air, so that more fuel can be burned per cycle.
A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure. [ 1 ] [ 2 ] Pressures of up to 5,000 psig are commonly produced by multistage reciprocating compressors.
In this situation the energy required to run the compressor drops suddenly, and the remaining hot air in the rear of the engine allows the turbine to speed up [citation needed] the whole engine dramatically. This condition, known as surging, was a major problem on early engines and often led to the turbine or compressor breaking and shedding ...
Compressor – Machine to increase pressure of gas by reducing its volume; Gas duster – Product used for dusting devices – (generally use fluorocarbons but some use compressed air.) Rotary-screw compressor – Gas compressor using a rotary positive-displacement mechanism
Animation of a spinning scroll compressor. Léon Creux first patented a scroll compressor in 1905 in France and the US. [2] Creux invented the compressor as a rotary steam engine concept, but the metal casting technology of the period was not sufficiently advanced to construct a working prototype, since a scroll compressor demands very tight tolerances to function effectively.
