Vortex II fans
Getting a new TT Monday. It, like most TT's comes with a weak, under powered fan that would be hard pressed to blow out a candle. In other trailers I've purchased, I have a Fantastic fan installed...

Not knowing anything, what are PWM's? And how do you install reversing switches?Lynnmor wrote:
I bought the cheaper single speed Vortex fan and added PWMs and reversing switches. Now I have full speed control in both directions without wasting energy like the resistors in the Vortex II.
Search eBay for PWM, you should be able to find videos to help on YouTube. A Pulse Width Modulator turns the power on and off rapidly, as you adjust the knob the time on varies to adjust the motor speed. A DPDT switch can be used for reversing by swapping the plus and minus.
It really is simple and cheap to do this.
