3 KDRE/KDRD fans have an external rotor motor with a mixed fl ow type impeller, i.e. the fan impeller is a combination between a radial and an axial impeller and provides the best from both impellers. The result is a fan that gives considerably more airfl ow than radial fans and still provides relatively high static pressure with a high level of effi ciency and a compact design. The casing is manufactured from galvanised sheet steel and provided with fl anges for a fast and effective installation. To protect the motor from overheating, the KDRE/KDRD fans have integral thermal contacts with leads...
