JACKSONVILLE, Fla. (Dec. 12, 2012) - American Coolair has developed a 54-inch NBC damper door fan for farm buildings that offers increased efficiency and easier maintenance.

The discharge damper doors are a sturdy and aerodynamic alternative to the common inlet shutter and the NBC54 features cast aluminum blades. 

American Coolair's innovative cast aluminum disc with captured bearings extends bearing life on the fans. The auto belt tensioner ensures continuous fan operation at full capacity.

The fans are certified through the Bioenvironmental and Structural Systems Lab (Bess Lab) at the University of Illinois.
