Can-Fan RK 4 Speed Fan
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-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.
