Extruded Aluminum 4" Deep Adjustable Louvers

4" adjustable louvers are operational from fully open to fully closed for

positive shut off of air intake or exhaust. 4" drainable adjustable louvers

are ideal for intake application and non-drainable for exhaust application.

These adjustable designs can be operated manually, electrically and

pneumatically. Blade and jamb seals are available for low leakage

application. The EA-406C is a combination louver with fixed and

adjustable blades in a single 4" deep frame. When the blades are in

closed position it provides excellent protection from the outside

elements while the exterior appearance remains similar to fixed louvers.

Louvers shall be designed to withstand 25 lbs. per sq. ft. (120 mph)

inward or outward wind pressure @ I/270 deflection. Consult Air Flow

engineers for higher wind loadings.
