Combination Louver/Dampers
Select adjustable blade and combination louver/damper products for intake or exhaust applications.

Operable extruded aluminum combination louver/dampers protect air intake and exhaust openings in exterior walls. The design allows for a fixed front blade appearance with operable damper blades that may be open or closed. When in the open position these louvers function as a conventional louver. When in the closed position they provide a tight shutoff from air and other elements. These louvers are most often supplied with factory mounted and adjusted electric actuators (exception for GCE and GCI products).
