Airolite’s Fabricated Adjustable louvers are intended for high volume intake and exhaust applications that require weather protection. When closed, Fabricated Adjustable louvers may be rotated to resist air leakage and water penetration. Fabricated Adjustable louvers are available in 20, 18 and 16 gauge material thickness and 4 to 6-inch frame depths.

625 is a fabricated metal, non-drainable, adjustable blade, gravity-operated louver designed for intake and exhaust air applications. The adjustable blades are capable of opening to a 90-degree angle to permit intake and exhaust ventilation. This design incorporates adjustable blades intended to open and close as a result of changes in static pressure differential produced by fans and other mechanical equipment.
