Greenheck Backdraft Damper Models Now AMCA Licensed

Several Greenheck backdraft dampers (BD Series, ES-10 and ES-30 Series) are now AMCA Licensed for Air Leakage and Air Performance. Designed to allow airflow in one direction and prevent reverse airflow, backdraft dampers can be used as exhaust or intake dampers.

BD Series dampers feature a galvanized steel frame and are available in horizontal- or vertical-mount configurations with velocities up to 1500 fpm. Featuring an extruded aluminum frame and an adjustable internal counterbalance, ES Series dampers are available in horizontal- and vertical-mount configurations with velocities up to 2000 fpm. Greenheck backdraft dampers comply with the IECC and ASHRAE 90.1 leakage requirements for non-motorized dampers.
