Single-stage air amplifier AAD series

Haskel AAD series air amplifiers are high-efficiency pneumatic pressure boosters designed to increase compressed air pressure for industrial applications requiring high pressure without electricity. Efficient means of increasing air pressure Pressure outputs up to 4500 psi (310 bar) Maximum outlet pressure area ratio + supply pressure Pump twice volume per cycle of AA range Requires less air drive since the inlet air pressure itself provides a substantial portion of the driving force An Air Pressure Amplifier is an air pump that is driven by part of the incoming compressedair supply enabling it to cycle and pump the balance of the supply to a higher outputpressure. Pressure is generated by the use of a differential area piston assembly (Fig 1).Low pressure air applied to a large area creates high pressure air on the small area. Cyclingis achieved through the use of two pilot valves that alternately pilot and vent the largearea end of an unbalanced cycling spool. The small area end of the cycling spool uses apermanent air spring. This unbalanced cycling spool ensures that the air amplifier cycles ondemand.
