The precise 4 speed control position enables the grower to allow for seasonal variation, yet still offer ultra reliable performance.
Fans with dimmer type switching can be set on unsuitable inefficient positions which can lead to fan failure. The German fan technology along with the Dutch growing experience have combined to find 4 lock in speed settings for each model that are not only beneficial in crop climate control but also assure the grower of safe reliable performance.
