High and Low Pressure Steam Exhaust Muffler for Boilers

A vent silencer (muffler) or a blow off silencer is a device used to reduce unwanted noise created by gas or steam flow in a pipeline discharging directly into the atmosphere.

The term vent silencer was derived simply for silencers used to attenuate noise produced by the expansion of Gas, Steam or Air at elevated temperatures to atmospheric pressure.

Vent silencers find wide applications in high pressure vents, steam vents, safety relief valve outlets, system blow downs and purge outlets etc. The predominant use range of Vent Silencer is within typical applications such as steam ejectors, steam and gas vents, process vents, turbine or compressor bypass systems and safety and relief valves.

Manly's silencer is the best solution for applications where any gas or steam need to be released to the atmosphere. Each vent silencer is designed to attenuate the noise level to the required sound pressure level criteria at a given distance from the silencer.
