RK-S  (with 4 Speed Controller)

The addition of the speed controller adds versatility. Each speed setting is factory set and calibrated to produce the most efficient output specific to each fan.

 No need for extra electronic speed controllers or transformers.

• Flexibility when the grower needs to make seasonal adjustments.
• Convenience; increases the ability to match fans with a larger range of filters.
• 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.
