This arrangement has an impellor directly mounted onto the motor shaft. The motor is outside of the airstream. The hub of the impellor protrudes from the casing. The fan is shown mounted onto an optional channel base. 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.
Maximum air temperature is 200ºC. The impellor can be removed from drive side, without having to disturb the inlet or discharge ducting.
