Combination Exhaust Louver/Backdraft Damper
J Blade
Application and Design
GCE-402 is a combination weather louver and gravity backdraft damper designed to protect air exhaust openings in building exterior wall. Design incorporates a drainable head member, J style stationary louver blades, pressure/gravity operated damper blades and sloped sill to provide maximum resistance to rain and weather. Recommended application is in close proximity (preferably ducted) to an exhaust air fan as pressures required to operate the GCE-402 may exceed pressure differentials available without an adjacent fan. This model is not recommended for barometric relief applications.

GCE-402INSTALLATION DETAILS
Maximum Size and Installation Information
The maximum single section size for the GCE-402 is 60 in. W x 120 in. H. Larger openings require field assembly of multiple louver panels to make up the overall opening size. Individual louver panels are designed to withstand a 25 PSF wind-load (please consult Greenheck if the louvers must withstand higher wind-loads). Structural reinforcing members may be required to adequately support and install multiple louver panels within a large opening. Structural reinforcing members along with any associated installation hardware is not provided by Greenheck unless indicated otherwise by Greenheck. Additional information on louver installation may be found in AMCA Publication #501, Louver Application Manual.
