GCE-402
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.
