The AMCA and EUROVENT certified radial fans used in small air handling units are used in forward and backward curved blades according to the required capacity and preference. Double suction radial fans are used with additional filtration. The radial fans are manufactured from belt-pulley and spiral galvanized steel body. The fan rotor is static and dynamically balanced. In order to regress the belt, the electric motor is mounted on specially designed belt tensioning mechanisms.

The pulleys are tapered and tight. The connection between the fan nozzle and the cell panel is provided by the connector. The fan motor and belt tensioning mechanism are connected to the reinforced C profile frame. In addition, the entire moving system is mounted on spring or rubber insulators. In Kzc air handling units, if frequency converters suitable for radial fans and motors are processed, they are applied separately. Illumination of the fan cell is provided by controlled hermetic armatures.
