The Bifurcated Case Axial range of fans has been specifically developed to meet the need for an axial fan which can handle atmospheres normally detrimental to the life of the fan motor.
By isolating the motor from the system airstream, the bifurcated fan can handle a wide variety of saturated and dust laden atmospheres, heated air and hot gases.
Maximum ambient temperature 200˚C
Motors are of the B3 foot mounting type, totally enclosed and fan cooled.
Where indicated, the motor is suitable for speed control when the ambient air temperature is not higher than 60˚C.
Single phase 220-240V 50 Hz supply are available in 5 sizes: -250, 315,400,450 and 500mm diameter. 250 to 400 diameters in either 2 or 4 pole versions, 500mm diameter in 4 poles.
Three phase 380-440V 50Hz supply are available in eleven sizes 250, 315, 400, 450, 500, 560, 630 in either 2 or 4 pole versions (710, 800, 900 and 1000 dia are available as 4 pole).
Motor insulation Class ‘F’ and IP55 protected against dust and water jets from any angle, allowing outside applications.
Adequate space is provided within the motor compartment to ensure a plentiful supply of cooling air. The air within the motor compartment must not exceed 40˚C.
Suitable for relative humidity levels up to 95% R.H.
