Roof Mounted Vertical Discharge Centrifugal Fan • 5 standard sizes from 315mm to 500mm • Air volume flow rates up to 2.66 m% • Static pressures up to 618 Pa • Suitable for operating temperatures up to +60°C • Can be mounted at angles of up to 30° • Available in AC Overview The Clearflow CF range of vertical discharge centrifugal roof fans incorporate advanced backward curved impellers, with three dimensional profiled blades. Easy Installation Can be mounted at angles of up to 30° which means the fans can be fitted directly to pitched roofs. Spigot is on the underside of the unit and can be fitted directly to the main duct. Space saving External roof mounting outside of the building is ideal where space is a premium. Bird guard fitted as standard to stop damage by wildlife. Efficient Performance Energy cost savings are achieved by providing the highest efficiency at operating point with virtually no air, performance or redirecting losses thanks to the unique impeller blade geometry. Weather Resistance Wind guard fitted as standard to reduce noise, and draughts entering the duct. Easily removable for cleaning and maintenance. Controllability A range of transformer voltage controllers used to provide five speed step control of single phase or three phase motors. Reduced fan speed can provide significant cost-savings through lower energy consumption in both mechanical energy of motors and also on the conditioning of replacement air. Warranty Each CF has a 12 month warranty.
