The basic working principle of gas or air compressor can be easily understood. Basically, it works by changing the volume of the gas or air. It uses a piston or diffuser to increase the pressure of the working fluid.

When the working fluid enters into a diffuser, it changes the speed of the fluid into pressure energy. In this way, a compressor compresses the gas or air. After the compression process, the compressed air is transformed into a storage tank.

Main Features
1) Simple structure in linear type, easy in installation and maintation. 
2) Adopting advanced world famous brand components in pneumatic parts, electric parts and operation parts.
