Lau’s extruded aluminum, low leakage control dampers are designed with airfoil blades for higher velocity and pressure HVAC systems. It meets the leakage requirements of the International Energy Conservation Code by leaking less than 3 CFM/sq. ft. at 1” of static pressure and is AMCA licensed as a Class 1A damper.
These dampers feature airfoil blade design for low pressure drop and less noise generation, positive lock axles, non-corrosive bearings and shake proof linkage for low maintenance operation and the blade edge seals mechanically lock into the blade for superior sealing.
