ELC445D Combination Louver
The ELC Combination louver has a 4" frame and a 45 degree fixed blade angle. It features:
- 39% free area.
- Low water penetration and low pressure drop.
- Concealed blade linkage is protected from weather exposure and reduces required installation depth.
- Adjustable rear blades provide desired shutoff in the same 4" deep frame normally required by a louver alone.
- A drain gutter in each stationary blade and downspouts in jambs and mullions drain water from the louver with minimum water cascade from blade to blade.
