Duct Axial® Fans

Series 46 Belt Drive Duct Axial Fan | Hartzell Air Movement
Series 44, 44V, 46, 46V, 48, & 48V

Duct Axial® fans include propellers designed with higher hub-to-tip ratios, minimizing the backflow of air at higher pressures. They also incorporate a propeller design that does not include a stall characteristic. This allows the unit to respond to changing system characteristics without experiencing stall, vibration, and destructive consequences. These fans are in marine duty construction, however, this is not standard.

Duct Axial® fans features a six-blade, cast aluminum, airfoil propeller mounted with split-taperlock bushing and a safety retainer plate for easy installation and removal. The one-piece housing is constructed of heavy-gauge, hot-rolled steel with a continuously welded steel drum and flanges. 

An optional vane section improves performance at many operating points.
