• ##### Air Compressor

Air compressors were designed to compress air to higher pressures and harness this potential energy source. Unlike other sources of power, no conversion from another form of energy such as heat is involved at the point of application. Compressed air or pneumatic devices are therefore characterized by a high power-to-weight or power-to-volume ratio.
