Backward inclined flat fans are constructed with highly efficient flat blades, backwardly inclined to match the velocity pattern of the air passing through the fan wheel. Resembling some of the characteristics of the airfoil fan, these centrifugal fans are not ordinarily used when gases contain sticky material or abrasive dust. A backward inclined fan features a unique, non-overloading characteristic, allowing the horsepower required by the fan to actually decrease when the flow rate increases past a certain point.
Contact Process Barron for more information about our mechanical draft fan design and fabrication services. Our engineers and service technicians can assess your operational requirements, and construct the proper centrifugal fan for your application needs.
Backward Inclined Flat Fan Construction and Accessories
Process Barron can custom fabricate a new or replacement backward inclined flat fan from a variety of heavy duty steels or exotic alloys. Fan rotors are balanced to ANSI standards, and finite element analysis and other advanced testing processes ensure stable design and accurate fan performance.
Backward inclined flat fans can be found in forced draft and reduced draft service for variety of industrial applications including heat recovery, incineration and combustion air in chemical plants, power plants, foundries and refineries. Process Barron’s mechanical draft fans are available with several options and accessories including inlet and outlet dampers, inlet boxes, access doors, and silencers often required in high-pressure applications.
