Axial Fans Catalogue (50Hz) JM Multi-Stage - Cased Axial Fans Features • 400 - 630 mm diameter • Volume up to 25,920 m /h (7.2 m /s) • Static pressures up to 1000 Pa • Fans tested to ISO5801 and BS848 • High energy efficiency • Low installed noise levels • Motor protection IP55 • Overheat protection fitted as standard 3 Electrical Supply • -40ºC to 50ºC as standard • BT or CT motors can be continuously operated at temperatures up to 70ºC Product Code 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 offer thin aerofoil sections for low generation of noise. Every cast aluminium component is X-ray examined using Real Time Radiography prior to assembly. Motors All motors are totally enclosed air stream rated class F insulation. Constructed from aluminium as standard with special ‘T’ slot or pad mounted fixings. Motors are suitable for speed control. 50 - denotes the fan impeller diameter in centimetres JM2 - denotes JM2 Fan Type ie, 2 stage fan 20 - denotes impeller hub diameter in centimetres 4 - denotes a nominal 4 pole speed 6 - denotes the number of blades 32 - denotes the pitch Angle for the required duty Suitable for horizontal through to vertical shaft operation. Supplied IP55, with removable drain plugs. Sealed for life bearings lubricated with wide temperature range grease. Motors are fitted with thermostat overheat protection as standard. Three phase motors are suitable for inverter speed control down to 20% of full speed . Mounting Feet Flexible Connector Controls Inverter Casings MaXfan2 are available fully cased, complete with an externally mounted pre-wired electrical terminal box. Casings 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.
