Sound-absorbing acoustic grilles are products that reduce sound vibrations to a certain level, depending on the air terminal model. They are needed where a ventilation duct outlet is located in a public area and could exceed the permissible noise level.

Design: This model is made entirely of galvanized steel. The blades are filled with a special sound-absorbing material. Grille depth 300 mm. A flange for fixing into building openings can be supplied.

Finish: Powder coating is applied at the factory in colours from the international RAL scale. Standard colour: white. The polyester coating reliably protects the metal against oxidation.

Size: The defining size is the overall size. Minimum recommended size 400x400 mm. Maximum size of a single one-piece grille 1600x2500 mm. For larger openings, grilles can be made of several sections. Please contact our managers for details.

Installation: Installed in the ventilation duct opening on the building facade. Can be fitted with a flange.
