Axial Fans Catalogue (50Hz) JM Aerofoil - Cased Axial Fans Features • • • • • • • • 315 - 1000 mm diameter Volumes up to 72,000 m3/h (20 m3/s) Static pressures up to 800 Pa Fans tested to ISO5801 and BS848 High energy efficiency Low installed noise levels Motor protection IP55 Larger sizes available please enquire for more information Temperature Range • 200ºC for 2 hours with 3 ph motors on one off emergency operation only • -40ºC to 50ºC as standard • 50ºC to 70ºC must be run at full speed only 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 inspection prior to assembly. The maximum pitch angles shown allow for speed control by frequency inverter (3ph only). 63 - denotes the fan impeller diameter in centimetres JM - denotes fan type 20 - denotes impeller hub diameter in centimetres 4 - denotes a nominal 4 pole speed 6 - denotes the number of blades 36 - denotes the pitch angle for the required duty All motors are totally enclosed air stream rated class F insulation. Constructed from aluminium or cast iron as standard with special ‘T’ slot, pad mounted and foot mounted fixings. Single speed motors are suitable for speed control by voltage regulation where indicated. Three phase motors are suitable for use with frequency inverters, suitable for turn down to 20% of maximum speed. Two speed motors are available on request. Suitable for horizontal or vertical shaft operation. Supplied IP55, with removable drain plugs. Mounting Feet Flexible Connector Controls Transformer Controls Inverter Controls Electronic Sealed for life bearings lubricated with wide temperature range grease. The BT and CT frames are fitted with overheat protection thermostat as standard. 80-160 frame motors are fitted with Thermistor OHP. These motors are suitable for inverter\speed control down to 20% of full speed and 
where within scope incorporate IE2 compliant motors. Casings JM Aerofoil fans are available in either a long cased form, complete with an externally mounted pre-wired electrical terminal box, or short cased for duct or plate installation. 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.
