Fans are only suitable for use at 100ºC or above, which makes the product exempt from ErP legislation. 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. 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.
