Material handlers are a family of SWSI centrifugal blowers that use a Radial design wheel. Designed primarily to move material through an industrial ducted system. Units are design for high strength and high speeds (RPM). Radial wheel designs include open type for granular material. Reinforced wheel for conveying larger or heavier material. Backplate type for conveying stringy or fibrous material. Optional air handling wheel is available for light dust or high temperature application.
