EADC-U Back Draft Damper

APPLICATION AREAS
Installed at the inlet or within air ducts in ventilation systems. Since it opens in only one direction according to the airflow, it prevents air movement in the opposite direction.

When the system is operating, the blades open under the effect of airflow. When the system stops, the blades close automatically, blocking air passage.

IMPORTANT NOTE
Depending on the installation method, the specified dimensions are given as (L × H), where L = width (blade length) and H = height.

FEATURES
The louver outer frame is manufactured from galvanized steel and provided with flanges, while the inner blades are made of aluminum. The blades are fixed to the outer frame using special bushings. Standard dimensions are listed in the tables. Custom production in any size is available upon request.

ADDITIONAL MATERIALS & PACKAGING
Packaging is carried out using polyethylene film. Since the louver is fragile and may deform, transportation must be handled with care.
