Impellers A unique high efficiency aerofoil section blade with a purposely smoothed hub and clamp plate for adjustable pitch angle availability. The Fläkt Woods impellers are all high pressure die cast to off er thin aerofoil sections for low generation of noise. Every cast aluminium component is X-r ay examined using Real Time Radiography prior to assembly. s All motors are totally enclosed air stream r ated class F insulation. onstructed from aluminium as standard with special T slot or pad mounted fixings. s are suitable for speed control. for horizontal through to vertical shaft operation. Supplied IP55, with removable drain plugs. Sealed for life bearings lubricated with wide temperature range grease. s are fitted with thermostat overheat protection as standard. Three phase motors are suitable for inverter speed control down to 20% of full speed. Electrical Supply V / 50Hz / 1 φ V / 50Hz / 3 φ Temperature Range -40 to 50 as standard. (All motors are not suitable for starting at temperatures lower than - 20.) Fans that include BT or T motors can be continuously operated at temperatures up to 70. When these fans are operating in excess of 50 they should be run at full speed only. Other fans can be operated up to 70 with appropr iate deration of motors. asings MaXfans are available fully cased, complete with an e xternally mounted pre-wired electrical terminal box. asings are spun from sheet steel with integral pre-drilled and radiused inlet flanges. The galvanised finish gives a high resistance to corrosion and is ideal for external as well as internal use. Accessories Silencers, Mounting feet, Vibration isolators, flanges, connectors, Air operated non return dampers, Guards, Bell mouth inlets. For a full range please see pages Application Guide
