Other types that fall under the positive displacement air compressors are the following: reciprocating, rotary screw and rotary sliding vane. The positive displacement compressor such as the piston air compressor works similarly with an internal combustion engine in a reverse manner. They could have cylinders, pistons, housing blocks, valves and crankshafts.
Another form is the non-positive displacement compressor. A type that falls under it is the centrifugal compressor.
Most industries prefer the industrial air compressor for their convenience. But even home owners could keep an air compressor pump around, for their needs. There are a variety of portable air compressors available.
This kind is suitable for people on the go or who travel. You never have to go through the tedious task of having to find a vehicle big enough to carry your high pressure air compressor wherever you wanted to go.

This type of air compressor pump has made possible major breakthrough in the study of marine life. It has helped many adventurers explore the beauty of the sea.
