Air ends are needed by compressor and compressed air system manufacturers. There are several different kinds of technologies to produce pressured air, for example reciprocating (=piston), membrane, vane, z-screw, liquid-ring, and turbo –compressors.

Wherever there is industrial activity, compressed air is usually needed. Although electric actuators have replaced the traditional pneumatic applications in some cases, there are and always will be new applications for compressed air (such as in fish farming).
