	Auburn Axial Induced Draft Fans for Commercial and Institutional Applications
	Fan Ambient air circulates around shaft and bearings, insulated from the hot gases by the ceramic fiber-filled air tube assembly.  The sub-assembly of fan, shaft and bearing assembly, motor and air tube is easily removable for service.  High temperature paint withstands up to 600° F without film failure.		Shaft & Bearing Assembly The shaft is machined from turned, ground and polished, medium carbon steel.  Tolerances of .001" eliminate misalignment through bearings.  Special fixed/float cartridge bearings are factory sealed with high temperature lubricant for extended life.
	Fan Wheel Heavy duty propeller type blade.  Electronically balanced.  Electro-coated enamel finish helps prevent corrosion.  Welded hub.		Motor/Pulley/Belt High efficiency totally enclosed fan cooled motor with 1.15 service factor.  Adjustable motor base allows for easy belt tensioning.  V-belt/pulley drive eliminates troublesome field alignment of shafts.
