Axial fans of the AR sileo series have a bionically designed blade geometry and are driven by external rotor motors. AR fans consist of a round casing with flanges according to Eurovent 1/2 made of galvanised sheet steel which is powder-coated black (RAL9005). The rotor is painted black (RAL9005). The axial impeller is made of fibre-reinforced plastic (PP) with a metal core. Impeller dynamically balanced in 2 planes according to DIN ISO 1940 part 1, quality class G6.3. For motor protection, the fans are equipped with thermostatic switches with lead-out cables for connection to a motor protection device. Motor cooling by arrangement of the motor within the air flow.
