fan No7 Pedestal Fixed Bung

This arrangement has a shaft and bearings supporting an overhung impellor. The bearings and shaft are outside of the airstream. The hub of impellor protrudes from the casing. The motor is mounted on an integral pedestal inline with the shaft and bearings. The shaft is driven by a flexible coupling. The fan is shown mounted onto an optional channel base, this is always strongly recommended for this arrangement. The channel Base comes in 2 variants, one with outriggers and one without. Outriggers enable easy drilling of foundation holes without having to mark and then move the fan.

A bung is welded to the drive side of the casing, maximum air temperature is 380ºC  with a 70mm bung and 450ºC with a 100mm bung. The casing is split horizontally (discharge angles allowing) to aid impellor removal. The impellor can be also be removed from the inlet side, but not from the drive side.
