The 6 Best rotary fan Speed controls (2023 reviews)

Compared with other control in this category, the labwork rotary fan speed control has a convenient design. This device does not provide a full range of speed control. It comes with your devices unplugged, turn the rheostat each way. The slower the fans' speed is the more opportunity for some fan noise. It really only works from about 1/2 to 3/4 speed and up. The speed is probably over 10, 000 rpm. It works well with polishing buffer. It comes with three foot cords and six foot cords, not a problem though.
