Compressed Air

Air Compressors

Rotary screw compressors operate on the principle of positive displacement. Filtered air enters the inlet of the airend where two rotors un-mesh. As the rotors re-mesh, the space is reduced on the opposite side of the airend and thus, the air is compressed and moved to the discharge port.

Air Compressors

Reciprocating compressors are a positive displacement machine, which means using a piston within a cylinder they increase the pressure of the air by reducing its volume, thus taking in successive volumes of air that is confined within a closed space and elevating this air to a higher pressure
