Four-sided, centrifugal blower with backward incline wheel. The four-sided housing design lends itself to customization for swingout design or other unique application. This unit is shorter in height and cost less compared traditional Single-Width, Single-Inlet blowers. Depending on point of operation, backward inclined wheel can be a more cost-effective selection compared to airfoil. In high moisture application the backward inclined wheel is the better choice versus an airfoil wheel. Used in a wide variety of application ranging from general ventilation, up to 500º restaurant exhaust and smoke control.
