An air compressor is a machine that is capable of converting electrical power into kinetic energy, specifically by utilizing compressed air. When this air is released in a quick burst, it releases an amount of kinetic energy that can be harnessed for a number of purposes, including pneumatic device activation, air transfer (such as filling a tire), and cleaning operations.
Air compressors work in two phases: the compression operation and the release operation. There are multiple methods of compressing air, including reciprocating pistons, rotary screws and centrifugal compression. Compression release, or air delivery, varies as well, and is measured in cubic feet per minute. Generally, the more horsepower a compressor is capable of, the more powerful the air delivery.
