Blowoff/Blowdown Vent Silencer

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 also referred to as Blow-down Silencers or blow-off 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. BCS is amount the market leaders in noise control engineering and is one of the premier manufacturers of vent / blow-down / blow-off silencers. Vent Silencer / blow-off / blow-down Silencers from BCS caters for all market needs whether highly specific or to suit a general customer requirement. Our team of skilled engineers use advanced selection software to optimise the best solution in terms of acoustic performance and budget.
