The Product
Suitable for residential and commercial applications including schools and offices, the Vent-Axia Rigid Duct Attenuator has been developed as a cost effective and compact way of reducing noise within a ventilation system. The light weight, low profile construction also provides corrosion resistance over metal silencers.

Technical Details
The acoustic lining of the attenuator contains
Microban anti-microbial protection, offering
enhanced resistance against mould growth and
also dust, fibre and formaldehyde.

The Vent-Axia Rigid Duct Attenuator is suitable
for residential and commercial applications
including schools and offices.

Noise Reduction

Offering excellent sound reduction over a range of frequencies, the Rigid Duct Attenuator is available in two lengths depending on the noise suppression requirements.

For MVHR systems the attenuator can be fitted on the supply side to habitable rooms, reducing airborne in-duct noise.

For MVHR and extract-only systems, the attenuator may be placed on the extract side to limit ‘cross-talk’ through ductwork between rooms.
