WebThe forward velocity vector of the air coming off the blades is fairly high. The result is a low fan speed. Static efficiencies are quite low because controlling and directing the velocity vector is difficult. An FC fan is intended for clean air applications only. Radial Blower WebSometimes, this type of fan has side rims. The blades tend to be heavier, but they are also narrower and deeper compared to both forward and backward inclined blades. Producing medium to high pressure and being able to move a higher mass or volume of fluid, this fan is best suited for material handling.
