GAF series acoustic louvres meet the requirements for noise attenuation both for ventilation systems and industrial applications. When used in ventilation systems, GAF series can replace usual industrial louvres, both in intake and exhaust. Therefore, two goals are achieved through a single product: on one hand it protects the external air intake as any other industrial louvre; on the other hand, it reduces outwards noise levels produced by the ventilation plant – as an ordinary silencer. A double-type version is available, in case higher noise attenuation is required.
In industrial applications, these acoustic louvres can be used both in standard-type version and double-type version. GAF can be used for the realization of enclosures and cabins, or inside technical compartments and, in wider terms, in all solutions for which both air flow and an adequate noise attenuation are needed.
Other designs are available on client request.
