Pressure instability, even a one-time pressure drop, frequently causes operators to elevate plant air pressure. But this fixed elevated air pressure also increases the air consumption of all poorly regulated processes…including the leak rate! For example, in a nominal 100 psig air system, a 15 psig increase in pressure will use approximately 10-12% more compressed air, PLUS use an additional 7.5% more energy. Installing an AAW PFE 4-in-1 Controller, combined with proper storage, will provide a capacitance (stored energy) for changing system air demands, eliminating the energy and maintenance costs associated with elevating the pressure or starting an additional air compressor while adding profit to the bottom line!

The AAW PFE 4-in-1 Forward Pressure Controller (FPC) constantly monitors the demand of air pressure and dynamically adjusts to utilize storage, increase volume flow and stabilize air pressure.

The AAW PFE 4-in-1 Back Pressure Control (BPC) allows excess compressed air capacity from one air system to spill over to another compressed air system. This is very helpful with centrifugals, keeping centrifugal loaded not blowing off.

The AAW PFE 4-in-1 Forward and Backward Pressure Control automatically switches control between forward system control (FFC) and back pressure priority control (BPC) based on user defined set points.
