Can I use a speed controller with this fan

[Nacimroc]

Just wondering can I install a speed controller on the fan below. I want to make a homemade air filter but its a huge fan. If so do you know suitable spec'd ones. Thanks

Yes, it can be controlled by varying the voltage. The speed controller needs to be suitable for a 'permanent split capacitor' motor drawing 1A. Motor noise may increase when using an electronic control, although it will not do so with an autotransformer.

I suspect the new models have a tapped aux winding for speed control.

Thanks for replies. I don't suppose you could recommend a suitable cheap and cheerful one?

The ebm-papst Ree50. I have tried to post a link but it won't have it. This is a 5A controller and they also do a 1A the Ree10 but I would opt for a bit more. Start the fan at 100% before you reduce the speed.

Here we go they also do other ratings. Google the part no and Farnells stock them but their link would not post up.
