Compressors are designed to compress (over 20 psi) and move air and other gases such as hydrogen, oxygen, nitrogen, etc. IPP's Compressors for sale are listed by the Cubic Feet per Minute or CFM rating and pressure.
Centrifugal compressors use centrifugal forces to pump air or gas to develop pressure. They typically operate at speeds of 3500 rpm or higher. Multiple stages are used to produce the required pressure rise. This type of compressor is driven by an electric motor, steam turbine, or gas turbine, with or without speed increasing gears.
Rotary compressors, blowers, and vacuum pumps are positive displacement type machines. This type of machine incorporates rotating internal lobes, screws or vanes that compress the gas or air. They are constant volume machines with variable discharge pressure. The volume can be varied only by changing the speed or bypassing or wasting some of the capacity of the machine. The types of rotary compressors are classified by the type of rotor they use. These include: straight-lobe, sliding vane, liquid piston, screw type.
Reciprocating compressors are furnished in either single-stage or multi-stage types. The principal parts of this type of machine are the cylinders and the pistons. The different types you will see include single acting air cooled or water cooled, single stage double acting water cooled, horizontal or vertical.
