Radial fans create a pressure difference. The resulting air effect is not in the axial direction, but functions in the direction of the centrifugal force, which we call (centrifugal). These fans also have a rotating impeller and a spiral housing in which that impeller is located. Air or gas enters from the center parallel to the axis, they are pressurized and transferred to the ducts tangentially around the impeller. These fans are the most basic equipment used in dust collection systems and cooling systems in industrial facilities.
