Heavy duty backdraft damper BD6
The BD6 backdraft damper is ideally suited to heavy duty applications that demand less than 12 cfm per square foot of leakage at .5" w.g. When the BD6 is equipped with the SPC (static pressure control) option, field adjustment can be made to maintain static pressures in the ranges up to .25" w.g. for dampers up to 17.3 sq. ft. andup to .75" w.g. for dampers up to 6 sq. ft. Aluminum construction helps maintain the damper's good-looking appearance and offers excellent resistance to corrosion. Contemporary styling features blades that overlap the frame for optimum weather resistance.
