The Centrifugal Blower Systems offer lightweight portability with the highest output available. See individual blower descriptions for CFM, weight and other specifications.

This blower offers flexibility by allowing workers to use high speed in applications such as purging an area, and the lower speed for sites such as dusty environments. The 8” (20.3cm) ports allow for positive ventilation or fume extraction. Large metal base and with integrated handles for support and portability.
