I had a contractor install a Fantech FR150 inline fan with this speed control -- a match made in Heaven!

I like the fact that the slide on this switch stays where you left it and the on/of is separate. The only thing negative about this switch (and it's huge), is that it only is available in white. I wanted it in black or any dark color.

Comments about Fantech Variable Speed Controller (SCD 5):

In our installation, the blower would have been much too loud and powerful at speed, so I am really glad I got this controller.
I recommend a lighted handle or pilot lamp that shows when the fan is running.

Great contoller for fantech variable speed fans. Slider can be set on one position while on/off function is contolled by switch. Switch is the weakest link, seems flimsy and does not provide positive feedback on its position. It does include a low speed trim adjustment for setting the slow limits of the slider. It can be ajusted nearly all the way down to 0 rpm.
