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.

645 is a fabricated metal, non-drainable, adjustable blade
louver intended for high volume intake and exhaust applications that require
weather protection. The adjustable blades may be opened to a 45-degree angle
to permit intake and exhaust ventilation and provide resistance to water penetration.
Adjustable blades may be controlled with manually operated hand-cranks, pull-chains,
fusible-link mechanisms, electric motor or pneumatic actuators.
