Do not use external fan controller.

Can-Fan RKLS plastic tube fan, is a speed controlled backward centrifugal extractor, using a resistant, maintenance free, plastic housing. The fan is equipped with a rotating switch that divides the maximum air flow of the extractor, into 4 different levels of performance. There is no need for additional electronic speed controllers or transformers; the speed change is possible using only the switch attached to the fan.

The Swiss made motor inside the Can-Fan RKLS has an integrated thermal switch that will turn the motor off, if the working temperature reaches a dangerous level.

Do not use any kind of Controller. For efficient performance with the best possible results, we strongly recommend the use of Can-Fan RKLS together with Can Filters.
