Single Inlet industrial radial fan with backward curved blades

The new BCE single inlet industrial radial fan series has been developed by COMEFRI in such a way that even with standard components at our disposal, our customers with special orders can be taken into consideration.

COMEFRI industrial BCE fans, developed with CAD systems, are designed with the following characteristics:

• compact design
• versatile applications
• high efficiency
• standardization of components (with less than 500 components, over 6.000 types of fans can be manufactured)
• Vmax = 250.000 m³/h
• Δ ptmax = 8.000 Pa

General: The single inlet industrial radial fans series BCE 25, BCE 17 and BCE 15, with backward curved blades, are suited for applications for both clean and slightly dusty air with temperatures of up to 100°C. By means of a cooling wheel, a fan can also reach temperatures in standard execution of up to 300°C (max. 200°C in settings 1 and 9). To reach high performance levels, components are constructed in geometrically optimal forms. The air flow of this base series reaches 250.000 m'/h, while the total pressure varies as follows: BCE 25 up to 3.500 Pa, BCE 17 up to 6.000 Pa, BCE 15 up to 8.000 Pa; in addition, this industrial fan is designed to operate at a low noise level and with high efficiency. The sizes follow geometrical gradations according to the series standard R 20. The nominal size corresponds to the outside diameter of the impeller.

Casing: The spiral shaped housings are continuously welded for all four series. They are designed with solid materials, which are appropriately reinforced, for industrial, heavy duty applications. Furthermore, all housing sizes up to size 1250 can be set in the 16 discharge positions. Inlet and outlet frames are integrated in the housing (DIN 24 159 part 3). Upon request, the housing can also be ordered in split execution (from size 1600 it is standard for the housing to be split).

Impeller: From the nominal size 400 upwards, the four series are finished and equipped with backwards curved sheet metal blades. Up to size 1250, the impeller can be removed both from the inlet as well as from the outlet. The impellers are balanced statically and dynamically on precision machinery in accordance with quality levels Q 6,3 (VDI 2060) and upon request to Q 2,5. In addition, a balance certificate can be made available directly from the balancing machine.
