An Air Pressure Amplifier is an air pump that is driven by part of the incoming compressed air supply enabling it to cycle and pump the balance of the supply to a higher output pressure. Pressure is generated by the use of a differential area piston assembly. Low pressure air applied to a large area creates high pressure air on the small area. Cycling is achieved through the use of two pilot valves that alternately pilot and vent the large area end of an unbalanced cycling spool. The small area end of the cycling spool uses a permanent air spring. This unbalanced cycling spool ensures that the air amplifier cycles on demand.

The ratio of the areas between the connected pistons is called the area ratio and is the “dash” number used in all model codes. This ratio and the available air drive source pressure determines the maximum outlet pressure of the air amplifier.
