SILENCER

Managing airborne noise is extremely difficult and problematic as there are so many contributing factors. Basically, the more air you try and move through smaller ducts, the faster the air travels and the more noise it makes. Our Silencer offer a quick fix solution to reduce air noise

• Small fan system attenuation
• Cross-talk attenuation
• System noise regeneration attenuation
• System terminal unit attenuation

Fan Silencers are available in standard 300 mm, 600 mm, 900 mm and 1200 mm lengths with non-standard lengths available on request.

Attenuator construction for this range comprises a pre-galvanised sheet steel spiral wound outercasing, manufactured in accordance with HVCA DW144 specification, with circular spigotted endcaps.

The inner bore is manufactured from pre-galvanised and perforated spiral wound steel tube, retaining a 50 mm thick scrim faced 45 kg/cu.m acoustic media.

Fan Silencers offer minimal resistance to airflow and can be used in a variety of noise control applications :-

• Small fan system attenuation
• Cross-talk attenuation
• System noise regeneration attenuation
• System terminal unit attenuation
