Abstract

The fan arrangement comprises a housing 34 having a central air inlet 36, a pair of centrifugal fans 48, 50 mounted at opposite ends of a hollow torque tube 46, and a pair of stub shafts 52, 54 projecting from each end of the housing. Flanges 88, 90 on the stub shafts are secured by bolts 92, 94 to the back plates 60, 62 of the fans and to the flanged ends 56, 58 of the torque tube. The arrangement enables an increase in the fan size and an increased diameter of the torque tube compared with prior art arrangements.
