125MM CAN FAN with a built in Fan Speed Controller (FSC)

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.


  • Model: RK 125LS
  • Diameter: 125
  • Max. Output (L/Sec): 84
  • Max. Output (m³/hr): 370
  • CFM: 218

Important information in selecting the right fan for the job:

  • Fitting a carbon filter will decrease the fan output by around 20%
  • Always aim to replace the air in a room every 2-3 minutes


The Can Fan RK series of fans use the same motors and air flow control as the RS range. They are encased in a moulded durable polymer body. It's a matter of personal preference for the type of casing you require, but the polymer casing has allowed for addition of the RK-S and RK-W fans.


RK-W (with Temperature Controller)

The integrated electronic thermo sensor on these fans helps to control temperature. The target temperature is easily set by the adjustment dial. When a variation of more than one degree occurs, it activates an increase or decrease in the speed of the fan until the target temperature is achieved again.

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.
