Abstract: This invention provides an air control system which is retrofittable in an inter mediate position between upstream compressors (130) and air storage vessels and downstream useful production equip ment (140) 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 (30) in parallel between a pair of header tanks (22) and controls them in response to sensed downstream pressures and to the pressure differential across the control system. Another embodiment includes control means to manage the loading and unloading of compressors to and from the air system.
