Abstract
A compressor system is disclosed with at least one fluid compressor for compressing a working fluid. At least one separator tank is structured to receive compressed working fluid from the compressor and separate air and lubricating fluid from the working fluid. A lubrication supply conduit is fluidly coupled between the separator tank and at least one compressor for supplying lubrication from the separator tank to the compressor. A blowdown pressure control valve is fluidly coupled to the separator tank. A controller is connected to the blowdown pressure control valve to control a pressure in the separator tank to a predetermined pressure at a compressor operating condition.
