Extra High Door (EHD) Unheated Air Curtain

Unheated

The Extra High Door (EHD) is used in industrial settings at large door openings. EHD units are manufactured in single increments that can be provided up to 30 ft. wide. The EHD 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.
