Four distinct speed settings via rotary knob

04SAFETY

Integrated circuit breaker for overload protection

A built-in circuit breaker monitors the electrical load, automatically cutting power if the fan draws too much current. This feature protects both the fan motor and the controller from strain, adding a layer of passive safety to daily use.

05COMPATIBILITY

Versatile fit for various fan types

Suitable for exhaust fans, high-velocity inline fans, and mini blowers, the device handles a wide range of applications within the 50 to 10,000 rpm speed spectrum. It plugs directly into a standard outlet, eliminating the need for tangled extension cords or additional wiring harnesses.
