Model FBH-43: Face & Bypass
FBH series is a horizontal style face and bypass control dampers are used in applications where face and bypass dampers are needed alongside each other. The units are connected causing one damper to open and the other damper to close.
-
Model FBV-43: Face & Bypass
FBV series is a vertical style face and bypass control dampers are used in applications where face and bypass dampers are needed one over the top of the other. The units are connected causing one damper to open and the other damper to close.
-
Model ICD: Thermally Broken, Insulated Blade, Low Leakage
Typically used to achieve additional protection where thermal conductivity is a concern. This model is available with a thermally broken frame for extreme cold applications.
-
Model VCD: Airfoil Blade Type, Low Leakage
Typically used in medium to high pressure and velocity systems. Airfoil blade with structural reinforcement through the entire length. All of these models include blade and jamb seals for low air leakage.
-
Model VCD: 3-V Blade Type
Typically used in low to medium pressure and velocity systems. Fabricated blades are reinforced with 3 longitudinal structurally designed vee's. Available with blade and jamb seals for low leakage applications.
-
Model VCDR: Round Blade Type
Typically used in low to medium pressure, and velocity systems. Available with blade and jamb seals for low leakage applications.
