Light acoustic louvre


Light acoustic louvreDescription

GAFI series light acoustic louvre is less thick and satisfies the needs of noise attenuation both in the ventilation systems and in industrial applications. In ventilation systems it can replace the common industrial louvre, both intake and exhaust.

Therefore by a single product 2 purposes are achieved: on one it protects the external air intake like any industrial louvre, on the other hand it reduces the noise produced by ventilation plant on the outside environment like any silencer.

The reduced thickness makes the GAFI series light acoustic louvre suitable in all those applications where the axial contents must be particularly small.

They can be used in the realization of enclosures, cabins or in technical compartments and, more generally, in all those applications that claim both the air transit and an adequate noise attenuation.

Besides the standard range, special designs are available on customer demand.
