Title: Noise attenuating snubber

Abstract: The pulsating gas flow tube is open to the surrounding acoustic surge chamber through a relatively large opening at the inlet end of the snubber and perforations in the tube, and the chamber is filled with acoustically penetrable media which broadens the frequency range over which the chamber is acoustically effective. To handle moisture-laden gases without loss of acoustical efficiency, a coalescing element is provided to collect and remove moisture and prevent the accumulation thereof in the media.
