The materials used to produce axialnfans with external power supply are steel sheets for ring and blades and steel for protective grids. All elements are coloured with black paint (ring and blades) or plastic coat (protective grid). Number of blades: 5. Rotating direction: Suction rotation – clockwise, blowing rotation – counterclockwise. Bearing: maintenance-free, type L10. Mounting position: horizontal or vertical. Insulation class: B, F. Mounting position: horizontal or vertical. Operating mode: continuous Type of protection IP54.
