The AL30 and and AL50 acoustic louver models provied acoustic solutions for situations where space and location do not allow installation of a full sized silencer.
The shutters are made of a "V" shaped maze through which air flows passing through high capability adsorbent materials.
The shutters are primarily used for:
- Air returns for air conditioning systems
- Inlet/Outlet in machine rooms dividing walls
- 300mm deep
- Height and width according to custom needs
- Galvanized steel construction or painted according to demand
- Anti birds netting and rain protection on request
- Nonflammable materials
