Backward Curved Blades
These fans have efficiencies nearly as high as the airfoil design. Its inherent strength means that in addition to handling air, it can be used with gases containing moderate amounts of erosive particles. It can carry liners and hard surfacing, if required. The robust design allows high tip-speed operation, and therefore this fan is often used in high-pressure applications where high temperatures are required.
Forward Curved Blades
Also termed radial tipped blades, used in high-volume flow rate applications when the pressure requirement is rather high and erosion resistance is necessary. this design reduces the potential for dust build-up on the underside of the blades in applications with moderate amounts of gas-borne dust. It offers medium efficiencies. The design is more compact than airfoil, backward curved or backward inclined fans.
Radial Blades
The flat blades of this type are arranged in a radial pattern, Forming a rotor which is essentially a large paddle wheel. This design results in a relatively inefficient fan with a power consumption higher than that using the much more common backward inclined blade. These rugged fans offer high pressure capability with average efficiency. They are often fitted with erosion-resistant liners to extend rotor life. Ggenerally used when high quantities of abrasive dust are present in the gas stream, or when very high gas temperatures are expected.The housing design is compact to minimize the floor space requirement.
*Centrifugal fans can be made single width single inlet (SWSI) or double width double inlet (DWDI).
