Nilfisk GMI and GMD Motor Aluminium Rotary Fan Elements Discontinued in the 90s, these are the last few new fans left.
The GMI and GMD motors were fitted in the Nilfisk GM80 and the Nilfisk GM90 and GS90 and the Nilfisk and Tellus GA71 GS81 and GM81 industrial vacuum cleaner and the Nilfisk GM82 and the Nilfisk GM625 Industrial Vacuum Cleaner
One of these fans will fit without problem in all versions, however, a pair MAY contact the stationary fans and hence lead to untimely failure.
