Abstract
In a regenerable collective protection system the turbine of an air cycle machine is driven by a potion of the clean air output of a pressure swing adsorber bed pair in the system. The beds in the pair are used alternately to cleanse contaminated air. They are then alternately purged of contaminant products. Valves are used to direct these alternate operations. The valve closures cause overpressures in the clean air output. The overpressures are predictable in relation to the valve actuation sequence and are removed by coordinating operation of a surge air bleed valve in the clean air output with valve actuation in the pressure swing adsorber bed pair.
