Our bnew rig has three of the standard model Fantastic Vents, the model with manual three speed controls. We had the fancy thermoostat model in the Dolphon and really miss the continuously ariable speeds, or at least the ability to run at very low, whisper quiet speeds. Can one of you electronics mavens suggest a way I can modify these fans to get lower speeds than the fairly high RPMs of speed #1? Conceptually I would like to install something that would cut all three speeds by 30-50%, so I have Real Slow, Slow and Half-fast instead of Fast, Faster & Fastest! ;D I'm thinking if I could insert a "slow down device" on the lead to the fan motor, it would slow the output of the existing three speed switch.
Is is as simple as adding an in-line resistor or do I need a PWM type motor controller or something different altogether? What size and type component should I be looking for?
