Vent Silencer Product Guide

PULSCO has been designing and manufacturing industrial grade acoustic silencers to meet customers’ specific requirements for over 50 years. PULSCO Vent Silencers reduce the noise produced by the expansion of gas or steam from elevated pressures to atmospheric pressure. These absorptive silencers are used to suppress noise generated by high velocity gas streams such as steam vents, safety relief valve outlets, system blow down and purge outlets. Each vent silencer is designed to attenuate the noise level to the required level criteria at a given distance from the silencer.
