SERIES 11 FANs<br />
Series 11 fans are bolted to the rotor, coupling,<br />
or ratchet mechanisms rather than being bored<br />
to fit the motor shaft. They may be used for<br />
squirrel cages or wound rotors or for vertical<br />
pump motors. The thickness of the hub area of<br />
these fans is the same as the back plate.<br />

SERIES 12 FANs<br />
Series 12 fans come in two or more pieces<br />
which are bolted to a machine shaft, or are<br />
clamped together. This type of fan is useful if<br />
it is necessary to remove the fan from a shaft<br />
joining two parts of a machine that is difficult<br />
to disassemble. The list price includes all<br />
pieces required to assemble a complete fan,<br />
but does not include charges to bore and<br />
machine the split surfaces of the fan. (See<br />
Table B2 for the additional charges.)<br />
