ABSTRACT:
This invention provides an air control system which is retrofittable in an intermediate position between upstream compressors and air storage vessels and downstream useful production equipment or the like to provide benefits of greater air-utilization efficiency and a better air system balance between supply and demand, especially on an air-weight flow basis. A preferred embodiment employs a plurality of servo-driven flow controllers in parallel between a pair of header tanks and controls them in response to sensed downstream pressures and to the pressure differential across the control system.
