Extruded Aluminum 4" Deep Drainable Louvers

4" drainable louvers are ideal for either fresh air intake or exhaust

application, but are best recommended for intake application where

they offer with extremely high free area and low water penetration.

Louver blades have gutters that collect water and drain it to channels

in jambs and mullions, which carry it to bottom of unit and away

from opening.

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.
