摘要

A method and apparatus for removing and replacing an integral-motor fan from below. A support assembly has support struts fixed to a mounting ring. Mounting ring is configured to be fixed to the fan head, holding the fan in place, and support struts are configured to rest on mounting bolts fixed to a fan shroud. To mount a fan in place from below, the fan is fixed to the mounting ring of the support assembly, and the support assembly and attached fan are lifted into the fan shroud. The support assembly is rotated until the struts align with the support bolts in the fan shroud. The support assembly is then lowered until the struts come to rest on the support bolts. A power cable with a length sufficient to lower the fan support assembly out of the fan shroud prior to disconnecting the power cable from the fan body.
