Backward Curve Heavy Duty Fans

Backward curve heavy duty fans or industrial heavy duty fans are used for supply and exhaust of air, gases, fumes and other industrial process. Limit load power characteristic with low noise level and 80% efficiency are also available with us. High Efficiency, Non-Overloading Backwardly Inclined Blowers designed and constructed to deliver large volume of air at  medium to high static pressure quietly and efficiently. Utilizing 'Backwardly Inclined' centrifugal impellers, the "BI" Blowers are best suited for process gas handling applications. Backward inclined blowers can be constructed in Aluminum, Stainless Steel and or coated with a wide range of corrosion / chemical resistant protective coatings.   Backward Inclined Blowers can be belt driven, direct coupled or close coupled.   At direct drive 'motor' speed, Backward inclined blowers may also be ordered with special narrow width impellers.  • Design : SISW and DIDW  • Temperature Application : 400oC  • Sizes : 300 to 2000 MM  • Wheel Dia Capacity : 750 to 230000 M3/HR  • Pressure : 6 to 355 MMWG Industrial Implementations: Whenever a new industrial fan is developed, all the previous experience in construction and manufacturing gained from similar applications is fully utilized. The smooth running of the fan is guaranteed by the precise electrodynamic balancing of the fan impellers and bearing vibration monitoring.  Our Heavy Duty Industrial Fans will give maximum performance in the most challenging of conditions. These backward curve heavy duty fans or industrial heavy duty fans are supplied to the Iron and Steel Industry, Cement Plants, Boiler Manufacturers, Power Stations, Mines, Chemical Industry, and to a wide variety of Industrial Engineering Applications.
