Backward Inclined Industrial Fans

Backward Inclined Industrial Fans (BI)

Chicago's Design 10A BI Industrial Fan is a rugged multi-purpose centrifugal fan equipped with backward inclined wheels suited for harsh duty applications. With heavier blades to resist erosion and corrosion, the fan provides reliable operation in contaminated air with minimal maintenance. Similar BI wheels are used in Chicago's SQB fans for alternate duty applications. For clean airstreams, Chicago's airfoil bladed fans are recommended.

Backward Inclined Industrial Fan Applications

Chicago's backward inclined blades are designed to handle corrosive or dusty airstreams. Typical applications include oven circulators, dust collectors, fume exhausters and emission control systems. The BI Industrial fan is one of the industry’s leading high temperature industrial exhaust fans as it is suited for up to 800°F. The solid steel blades are ideal for custom applied corrosion resistant coatings.
