Function of the compressor?

The function of a compressor is to increase the pressure of a gas or air by reducing its volume. This is typically done by using a piston or rotating impeller to compress the gas or air, which increases its density and allows it to be used for various applications such as powering pneumatic tools, refrigeration systems, and air conditioning units. Compressors are essential components in many industrial and commercial processes where compressed air or gas is needed.
