Sometimes a noisy fan in the bathroom isn't a bad thing. :yikes:

I did the same on my new Cougar in the bathroom. I went with the Vortex II, 3 fwd sowed and 2 reverse speed. Not too sure of the reverse ones though, being do close to the black tank vent pipe on the roof...

I also installed a remote wall plate switch, since mine only operated with the push button on the fan itself and my wife is 4'11" on a good day.... Got it from ebay for $13 USD

You’ve probably already experienced this Ray: when you flush with the fan on, it pulls the odor right out of the black water tank into the room. The Best to close the lid first, or turn the fan off after the flush.

Ray,

Nice simple mod...I always wondered how well those worked. When I bought my Fantastic Fan it was only a few bucks more than what you paid for the Vortex...time flies! I'll recommend yours to my friends who still have the o.e. types in their rigs. Thanks again for the great video and cheers to you both also.

My old fan used to do that too sometimes, Guess since its such a small room.

Thanks, Drew tell them its best to get the one with 3 speeds. As the single speed is always on high and it really sucks! haha. I'm gonna DIY a variable speed control into mine, to give me more options.

Ray,

Ok will do, thanks.

Wow, I just found the 3-speed with reverse on Amazon for 54 bucks!

Nice! The same one on Amazon Canada goes for $131 CAD about 100 USD.

Just added the same (single speed) in our micro minnie bathroom last week. Install was straight forward, moves a lot more air than the original OEM, but it was noiser than I thought it would be.
Ray, any concerns with the weigh of the new unit only being supported by two screws? I did use loctite on the two screws.

In this video, I install a DC motor variable speed control for my new Heng's Vortex bathroom fan. The fan was a little too loud and only had a single-speed which was full blast.

Several commentators on the video said they had improved things by installing the variable speed controller. I sourced one on Amazon and got to work.

One snag though. The new motor controller arrived defective, and I had to fix it. A wire had come loose from its solder joint. Thankfully it was easy to resolve.

I installed the motor controller on the outside under the vent cover using Etenabond tape to protect things and keep them in place. Wiring was straight forward. I simply used butt connectors to spice inline with the existing power wiring.

First impressions are a thumbs up! I love having the full adjustment of fan speed. At lower speeds, the fan is much quieter.

I think the screws should be fine unless over time the plastic gets brittle. You could always add some silicone rubber here and there for extra support.

After seeing this video I went ahead and replaced my OEM bathroom fan which was toast with this unit. No instructions arrived with the unit so I'm glad I watched the video. Even then it took a little bit of effort to get those gears to line up.

Thanks for the video and the product

You're welcome. :) :up:

In the video, I replace the flakey push-push power switch on my Vortex bathroom fan with a marine toggle switch.
