AUTOXBERT RV Side Exhaust Fan, 25W 12V Small RV Vent Fan Side Ventilation Exhaust Fan for RV Motorhome Camper Trailer Caravan Appliances Range Hood Vent, Black

I bought two of these vents. They have an exhaust fan and are prewired. I installed them in a matter of minutes in my travel bus. They will work great in my solar setup to exhaust battery heat and in the shower to exhaust moisture.They do not have screen on them to prevent insects from entering. I cut and epoxied screen onto them for this reason. Now they will also prevent bugs from getting in my bus.I think an improvement would be to have screens on them as a great selling point.Otherwise, very happy with them.

Bought this for a camper. I had put a solar inverter in the closet area of my camper, which tend to make a bunch of heat during the day. This gets rid of the heat. It moves a lot of air. They are about the size of a can of Coke for reference

Not happy with this after being installed for a little over a year. I installed this in my truck camper in my stove hood, because it didn't have an exhaust fan. Here arey issues. It doesn't have a swing door on the outside, so when not being used, air is allowed to come in, a long with bugs. It's just open to the elements. I wish I would have thought about this before installing. Another thing, it's very loud and only runs at full blast. I tried to use a dial in line, but then the fan geeks out and doesn't want to work at all. Don't buy this. You will regret it.

We connected the two fans in series electrically so it runs at half the power and is also quieter. Nice addition to our camper fridge

These fans were purchased for in in cold weather and out in cold weather for my solar system. After adding them to my system I had a fuse break aperantly they can not run in reverse. Not worth my time. I will be looking for replacements.

I have an issue with my enclosed atv trailer of moisture. I put the quads in there wet, the water evaporates off the machines, and it gets crazy humid inside. I used this blower with a timer to automatically run for a half hour a couple times a day. It does a great job of getting fresh dry air in there and keeping it a lot less stagnant and wet inside, and has a low enough current draw that I don't have to worry about it killing the batteries quick.

This thing is crazy loud, and moves very little air.

i built a couple of portable power stations for burning man and used these fans to keep them cool. they do move quite a bit of air and did a good job of keeping the boxes containing Lifepo4 batteries, a solar charge controller, and an inverter cool during very hot weather and while the equipment was generating lots of heat in a small enclosed box.
