When the CFD-521-IP and CFD-521-NP dampers are configured to close within 1/8” of the top of the gypsum board used in wood truss floor/ceiling and roof/ceiling assemblies, duct connections can now be made on the top of the damper, or any combination of sides of any size. This applies for all standard installations. Additionally, the plenum height can now be extended to allow duct connections in roof/ceiling assemblies with increased insulation to adhere to new, more stringent guidelines.
The EFD-635 drainable blade louver is designed to prevent.water penetration in non-wind-driven rain applications by collecting water in frame and blade gutters and channeling it into downspouts and away from airflow paths. The EFD-635 is available in a wide array of anodized and painted finishes including custom color matching.
