Centrifugal Fan Blower Impeller:
Impeller mounted directly on motor shaft journal
This arrangement is a compact, reasonable design and requires no transmission journal. However, it must not be used for gas temperatures of over 80°C, places a high load on the front motor bearings, leaves little space for a packing box and has a fixed speed (unless a frequency transformer is used).

Impeller mounted between the shaft bearings
This arrangement has a stable, robust design, requires no transmission journal and resists high temperatures. It is designed for the very largest fans and has plenty of space for packing box/cooling plates and auxiliary drives. However, it has an expensive shaft, requires demanding design work, a suction box, two packing boxes and an expensive fan and has a fixed speed (unless a frequency transformer is used).

Impeller mounted on free shaft journal – belt drive
This arrangement allows the possibility of varying the fan speed by changing the pulley. Plenty of space is supplied for the packing box/cooling plate and it has a good arrangement in a confined space. However, the transmission journal is belt drive and the shaft must be specially designed if the diameter must be increased, if large motors are used and if the belt forces are high. Also, it requires more maintenance in terms of adjustment/tightening the belt drive and is relatively large.

Impeller mounted on free shaft journal – belt drive on oblique pendulum
This arrangement allows the possibility of varying the fan speed by replacing the pulley and provides plenty of space for the packing box/cooling plate. However, the transmission journal is belt drive and the shaft must be specially designed and the diameter increased, if necessary, by using large motors and high belt forces. Also, it requires more maintenance in terms of adjustment/tightening of belt drive.

Impeller mounted on free shaft journal – direct drive through clutch
This arrangement features a stable, robust design, no transmission journal, resistance to high temperatures and plenty of spaces for packing box/cooling plate. However, it is relatively large and operates at a fixed speed (unless a frequency transformer is used).
