JM Aerofoil Bifurcated - Cased Axial Fans - 1

Axial Fans Catalogue (50Hz) JM Aerofoil Bifurcated - Cased Axial Fans Features • • • • • • 400 - 1000 mm diameter Volumes up to 62,280 m3/h (17.3 m3/s) Static pressures up to 980 Pa Motor protection IP55 Fans tested to ISO5801 and BS848 Overheat protection available Temperature Range • Suitable for temperatures between 100 °C and 200°C (continuous operation) 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 component is X-rayed using Real Time Radiography inspection prior to assembly. The maximum pitch angles shown allow for speed control by frequency inverter. 63 - denotes the fan impeller diameter in centimetres JM. Bif - denotes bifurcated variant 20 - denotes impeller hub diameter in centimetres 4 - denotes a nominal 8 pole speed 6 - denotes the number of blades 30 - denotes the pitch angle for the required duty All motors are totally enclosed fan cooled class F insulation with protection to IP55 and are IE2 compliant. All motors are supplied with sealed for life bearings or extended lubricators. Rubber anti-vibration mounts can be used, but only if the mounts are below the fan and the temperature at the anti-vibration mount is less that 80˚C. These motors are suitable for inverter speed control down to 20% of full speed. Casings Bifurcated fans are available long case only. Long casing covers impeller and motor and has duct mounted terminal box. The hot dipped galvanised casing gives a high resistance to corrosion. Mounting Feet Flexible Connector Controls Inverter Motor is mounted inside a tunnel, so is ‘out of air stream’. Only for use at 100ºC or above, which makes it exempt from ErP legislation. If the temperature of airflow within a bifurcated fan system is above ambient, FWL recommend that the fan is allowed to overrun so that any excessive heat is removed from the system. Failure to do this could mean that heat will transfer via the shaft/casing to the motor tunnel, which could cause degradation of the grease and lead to premature failure.
