Nilfisk GSD Motors and GM vacuum cleaner motor pod blower coupling. These are used for directing the exhaust air away, or intigrating the blow function into say a jigsaw table where there are ball bearings to enable the work to be moved easily, or for use in hovver beds in hospitals.
Simply remove the handle, take off the diffuser pack complete, PN 21573001 and fit this blower fitting, and hold it securely by re-fitting the handle. Then the motor can simply be used as a yard blower.
