Acoustic louvre grilles are products that reduce sound vibrations to a certain level, depending on the air terminal model. They are required where the ventilation duct outlet is located in public areas and the noise may exceed the permissible level.

Design
This model is made entirely of galvanized steel. The louvres are filled with a special sound-absorbing material. Grille depth is 100 mm. It can be supplied with a flange for fixing into building openings, as well as with a steel mesh against insects and birds.
Finish
Powder coating is applied at the factory in colours of the international RAL scale. Standard colour is white. The polyester coating reliably protects the aluminium from oxidation.
