Increase Air Pressure by 4 to 1
Offset Your Air Pressure Needs
Air amplifiers are air driven and can be used to increase available air pressure by a
ratio of 4:1.

Outlet pressure up to 500 psi (35 bar) can be easily achieved.

Wherever your air pressure is too low, use an air amplifier to increase local pressure.

Save major changes to existing systems.

Amplifier Types (Weights & Porting)

Amplifier Air Differential Piston
When Greater Pressure is Required
When a compression ratio greater than 2:1 is required, an air amplifier with differential piston is used.

A relatively small pressure applied to the large piston area, resutls in a much larger pressure generated on the smaller area at the base of the plunger.

Dividing the large area/small area gives the compression ratio.

Once the required pressure is achieved, the forces on top of the piston balance with the forces on the bottom of the plunger, and the air amplifier stroke stops.

No further energy is used to maintain the required pressure.
