Acoustic louvers are narrow silencers and are a great solution for limited space locations, they are also suitable for front air ducts in buildings.
The louvers are equivalent to rectangular silencers but have higher pressure drops as a down side.
Acoustic louvers can be used in acoustic walls to allow free airflow if desired and still achieve high levels of noise reduction.
Louvers are manufactured in three main models depths 30, 45 and 60 cm, providing noise reduction of up to 22 dB. (a).
The shutters are made of galvanized enveloped steel and internal noise absorbing fixtures tunneling the air flow through a maze.
The louvers are custom made on demand to fit in size and allow proper air flow.
