To convey fluids at temperatures above 60°C the impeller hub is equipped with the heat spreading impeller, the presence of which does not affect the size of the ground seat attachments compared to these shown in the dimensional tables of the individual fans, either for directly coupled fans or for transmission fans. However, in the case of directly coupled fans the dimension shown in the following table should be added to dimension B describing motor overall size (refer to the overall dimensions of the individual fan).

*) For size 315, in addition to the size of the motor, also the dimensions of the seat are different; it is therefore advisable to request the effective overall dimensions.
