The AXC inline duct fan is for commercial and residential situations where powerful, yet quiet, air delivery is required. With the optional VSC3 solid-state speed controller, the AXC can deliver 100 percent controllable air in a compact package. The manufacturer also reports that the unit combines an efficient airfoil impeller and a shielded ball-bearing motor in a steel housing with baked-epoxy finish for a maintenance-free installation. Other features include backward-curved impeller and external rotor motorized impeller. The product is always in stock for immediate delivery.
