fan No7 Pedestal Fixed Lagged

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.

RHF uses integral lagging, this means that all of our fans are engineered to allow for integral lagging as standard. The lagging is encased in a ‘second skin’ which not only gives a more aesthetically pleasing finish but allows for easier maintenance as the lagging does not have to be removed.

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