Can I use a speed controller with the TD-Mixvent, TD-Silent, and PV-Powervent series?

Yes, you can use a speed controller with these products. We recommend that you select a minimum 5-amp solid state speed controller.

Please be advised that although most general speed controllers will allow the user to modulate from 0% to 100%, that the TD-Mixvent, TD-Silent, and PV-Powervent series are not designed to have their power reduced to less than 75%. That is to say, that when using a speed controller, the user should not reduce the speed by more than 25%.
