The AC Series Acoustic Louvre is a multi-purpose louvre which permits the flow of air whilst minimising the noise from mechanical plant into the environment. The AC series acoustic modules fulfil a wide range of performances.

By using the AC series the benefits include a smaller footprint within the building compared to similar acoustic manufacturers. When combined with our UL screening / weathering louvre systems they meet the high level of architectural standards expected of a modern day building.

By using galvanised steel construction together with an inert vermin proof, non-combustible acoustic infill and an optional Polyester Powder Coat finish the system meets superior high frequency performance ideal for use with ventilation systems and acoustic noise barriers / plant screens.

Comprising profiled blades formed from solid outer skin and perforated inner. Blades will be packed with an inorganic infill to at least 47Kg/m3 and
compressed to not less than 5% to eliminate voids.

All AC series acoustic louvres offer a 32% MFA.
