Vent Silencers & Blow-down Silencers

Controlling noise associated with venting pressurized gases to the atmosphere is a priority for many organisations. It is essential that all installations have the required noise control measures in place that ensures the facility meets with the relevant noise criterion.

Vent silencers / blow-down silencers reduce the noise produced by the venting of pressurised gas to the atmosphere, especially air, steam and other gases such as nitrogen and oxygen.
