Aluminum Drainable Combination Combination louvers combine the aesthetic appearance of stationary louvers with positive airflow shutoff capabilities. Drainable models provide excellent water penetration protection at high velocities. ELBD375E : Automatic Exhaust Dual Combination Aluminum LouverThe ELBD375E Automatic Exhaust Dual Combination aluminum louver combines a drainable blade louver and an exhaust backdraft damper in a nominal 6” frame depth. Louver blades are .081” thick extruded aluminum at approximately 4” c-c spacing. Backdraft blades are .025” thick formed aluminum with concealed blade linkage, synthetic bearings and non-metallic blade seals. It features: - Approximately 45% Free Area.
- All aluminum construction for low maintenance and high resistance to corrosion.
- Operable blades that begin to open at approximately .03” w.g. pressure and are fully open at approximately .10” w.g. pressure.
- Maximum recommended exhaust free area velocity through louver: 1,500 fpm (457 m/min).
ELBD375I : Automatic Intake Dual Combination Aluminum LouverThe ELBD375I Automatic Intake Dual Combination aluminum louver combines a drainable blade louver and an intake backdraft damper in a nominal 9" frame depth. Louver blades are .081" thick extruded aluminum at approximately 4" c-c spacing. Backdraft blades are .025" thick formed aluminum with concealed blade linkage, synthetic bearings and non-metallic blade seals. It features: - Approximately 40% Free Area.
- All aluminum construction for low maintenance and high resistance to corrosion.
- Operable blades that begin to open at approximately .03" w.g. pressure and are fully open at approximately .10" w.g. pressure.
- Maximum recommended intake free area velocity through louver: 550 fpm (168 m/min).
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.
ELC6375DAX : Combination Louver The ELC6375DAX Combination louver has a 6" deep frame, 6063T5 extruded aluminum with .125" (3.2) nominal wall thickness. It features: - 47% Free Area.
