The ATAB Adjustable Pitch Airfoil Axial Fan is designed for where it is advantageous to have the motor out of the airstream due to the presence of corrosive or hazardous fumes, or dirt-laden, hot, or moist air. ATAB features a unique blade design that maximizes energy transfer to the airstream with minimum noise. The pitch on each blade can be manually adjusted while the fan is stopped. This feature allows the user to balance the present system while affording the flexibility of further possible pitch adjustment in the future. The ATAB also utilizes a unique cast iron housing, containing both bearings and the fan shaft as one assembly.
