Air compressors have many uses, such as supplying clean high-pressure air to fill gas cylinders, supplying clean moderate-pressure air to a submerged surface supplied air diver, supplying moderate-pressure clean air for driving some office and school building pneumatic HVAC control system valves, supplying a large amount of moderate-pressure air to power pneumatic tools, such as jackhammers, filling high pressure air tanks (HPA, air tank), for filling tires, and to produce large volumes of moderate-pressure air for large-scale industrial processes.
Air compressors are also widely used in oil and gas, mining and drilling applications as the flushing medium, aerating muds in underbalanced drilling and in air pigging of pipelines.
Most air compressors either are reciprocating piston type, rotary vane or rotary screw. Centrifugal compressors are common in very large applications, while rotary screw, scroll and reciprocating air compressors are favored for small and medium-sized applications
