Model EXA-645-CM

Extruded Aluminum Louver
6" Deep - 37.5 - 45 Degree Combination Blade

The EXA-645-CM combination louver features stationary drainable louver blades to protect against water penetration and an integral airfoil blade control damper to allow positive shutoff protection of air intake and exhaust openings. The EXA-645-CM closely reflects the available options and performance of the EXA-645-CM, with the added benefit of a spring return actuator concealed within the louver sill.
