Variispeed Manual Controller

Sold out

The Variispeed Manual Controller is used to reduce the airflow of duct fans.

This extra control is useful when noise levels need to be reduced, or when temperatures drop too low in the cooler months and fans need to be slowed down.

The Variispeed is simple and cost-effective, plug the controller into a power socket then plug the duct fan into the socket on the front of the Variispeed controller, reduce or increase the fan speed by turning the blue dial on the front of the controller.
