For the transport of fluids above 60°C a cooling fan is fitted to the hub of the impeller, the presence of which does not change the dimensions of the connections of the floor seat with respect to those given in the tables of the overall dimensions of the individual fans, neither for direct nor for transmission. In the case of direct drive fans, however, the dimension indicated in the following table must be added to the dimension B of the total dimensions of the motor (see overall dimensions of individual fans).
