Please note that linear bar grilles manufactured to order may take longer than advertised due to - what we hope is - a temporary material shortage. Lead time is currently around 2-3 weeks. We apologise for any inconvenience this may cause. All other grilles and louvres are unaffected.

Attenuators (Silencers)

Ventilation Ducting  |  Attenuators (Silencers)



Note

These attenuators or *'silencers' are suitable for temperatures up to 200°c and a maximum pressure of 1500 pascals. Excellent sound absorbing properties. Available in 10 diameters and four lengths as standard.

Construction
Casing:
Galvanised mild steel (BS2989)
Inner Lining:
Perforated galvanised mild steel (BS2989).
Sound Absorbing Material:
Mineral fibre slabs faced with glass tissue.

*Attenuators are often referred to as 'silencers' both within and outside the trade. The term is erroneous however as they do not silence a running ventilation system, but are very effective in attenuating the noise level.

In stock attenuators please allow 1-2 days.

Please use the drop down menu below to select the diameter of the attenuator required;
