Ten-Fourteen Door (TFD-ST) Steam Heated Air Curtain

The TFD is typically used over medium sized dock doors, or openings in an industrial environment and is equipped with a steam coil on the intake. TFD units are manufactured in single increments that can be provided up to 14 ft. wide. The TFD has top and bottom access panels to replace or service motors or blowers without lowering entire unit or bottom half of unit. All industrial units are direct drive, which avoids misalignment of couplers and outboard bearings and eliminates periodic belt replacement. The motor/blower plate comes out as an entire piece and all parts on the outside of the unit are constructed of stainless steel.
