To a to a 4 spoke angled cast aluminium fan (hand finished) found on the Energic motoculteur C7 B4L, C7 S Bloc and D9 S Bloc.(lubricated by a revolving click grease reservoir cup) on a slid axle.

The aluminium fan proved effective but quite fragile and would deform easily and break when knocked as they often were. These fans with blades intact are difficult to find. Often re cast aluminium fans, were manufactured to replicate the originals but were of varying size, non uniform construction and often of different sizes. Many people improvised with alternative fan blades, from weldings to car fans.
