Inexpensive bath fan upgrade.

I installed this fan in my camper 4 years ago, and have had no complaints. It sure moves a lot of air!

I bought the same fan and installed a PWM controller and DPDT switch so I can both control the speed and direction of the fan. I does let in less light than OEM but my wife doesn't complain when the boys go to the bathroom now.

At full speed its powerful enough to suck a piece of paper to the screen of a window at the opposite end of the trailer which makes it useful for drawing in cool evening air and venting cooking smells.

OEM fans are small and inefficient, yes.

But I see that this replacement has a smaller screen than my (and few others) OEM fans where screen covers the entire 14x14" opening. So there is less air flow when using it as a passive vent, and less light too.

The Vortex is a good upgrade over the OEM fan, and as Billy said, variable speed would make it even better. Just remember to turn it off before flushing... ;)

If that's the single speed model, it's worth it to add a variable speed control. The Vortex moves a lot of air, often way more than necessary. Slowing it down a little makes it much quieter too. I've been very happy with mine.

Nice. Thanks for posting.
