Acoustic louver ALW

ALW30 and and ALW 50 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 "W" 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
  • 600mm deep
  • Height and width according to custom needs
  • Galvanized steel construction or painted according to demand
  • Anti birds netting and rain protection on request
