560mm Impeller

Plate Axial Fans with a 560mm Impeller.
Commercial plate axial extractor fans. One of the most common varieties of fans, plate axial fans are normally mounted on a wall and vent straight outside. The size offered is diameter across the blades, the overall size (including the plate) is slightly larger. (See data-sheets.) A WSK gravity shutter is normally mounted externally. Available in single and three phase versions and most are speed controllable. Not normally used with ducting, for this use a cased axial fan type. All fixings available.
