|
|
Features
|
- The Aero acoustic louvre with its aerofoil shape blade design creates less air flow resistance to maximize air flow into stand-alone plant rooms, return air intakes and generator rooms.
- The Aero louvre offers up to 80% more air flow resulting in lower pressure drops.
|
Construction
|
- The weatherproof acoustic louvre series include 200mm, 300mm (SBL1) and 600mm (SBL2) models and with the compact depth of 200mm the Aero is ideal for applications in confined spaces.
- Tested to ISO7235:2003 proving to be a very efficient sound barrier.
- Available in galvanized sheet, aluminium and stainless steel.
