Line of motorized impellers includes 14 IP55-rated AC motorized models and 13 models of 24 and 48 VDC designs. The AC motorized impellers provide high airflow for harsh and demanding applications. The DC motorized impellers deliver a low power solution with standard control and monitoring features. Optional metal duct rings are available for both AC and DC models. Features include backward-curved plastic or all-metal blades; sealed dual ball bearings; and rugged die-cast aluminum frame. The motorized impellers provide long-life operation and offer maximum static-pressure values for restrictive environments such as electronic cabinets, enclosures and ventilation systems, says the manufacturer.
