A system for discharging compressed air from a compressor includes a air distribution manifold that is in fluid communication with the compressor via a conduit and at least one discharge line that is in fluid communication with the air distribution manifold. The discharge line defines a flow path from the air distribution manifold to atmosphere. The discharge line comprises a coupling pipe that is coupled to the air distribution manifold, a sparger section that is disposed downstream from the coupling pipe and at least one restrictor plate that is disposed between the coupling pipe and the sparger section within the flow path. The restrictor plate comprises at least one aperture that provides a pressure drop of the compressed air between the air distribution manifold and the sparger section.
