Fan Speed Controller: iPower Exhaust Fan Speed Controller Adjuster for Duct Inline Fan Vent Blower 350W

Buscaba reducir la velocidad de rotación de un molino de cafe de 200W, hace justamente eso. Si llega a fallar prematuro actualizaré la reseña, hasta ahora todo perfecto.

Item is much better than I expected. I was expecting it to have just a few clicks for speed adjustment. Instead has a rheostat knob with no stops. I am able to turn the knob slowly until the precise fan speed I desire is obtained. Using for an (extremely) oversized bathroom exhaust fan I recently purchased. Installed this speed control and was able to dial it to a much quieter level. I am planning on drilling a hole in the face plate of the exhaust fan to mount this for easy access and ability to adjust fan speed as needed. Will remove the knob and pass the shaft through a small hole for a finished look. No hum or overheating at all. Highly recommend this speed controller.

This item works perfectly to give me better control over a 20 inch orbital drum fan that already had 3 speeds but there was very little difference between high and low speeds. From what I read online I didn't think this would even work. But eventually I decided to take a chance and try it out. I am so happy that I did. It could not work better. The item has a very good quality feel. The dial to adjust speed it smooth and feels like it will last a very long time. Highly recommend. Even if what you want to control already has speed control this still gives you more control. Excellent product.

How's that for putting everything in the title? I use these with inline fans to pull cool air from the basement and circulate air upstairs where I appreciate the level of adjustment in both cases. Completely satisfied.
