Excellent vid. Two options when installing these that I learned: 1 = A seller on etsy offers dimensional polymer material about an inch thick to go under the roof sheet metal in place of a wooden ring. Proof against water damage, mold, etc.. I used it for my fan and AC unit. 2 = The electronics boards are prone to failure from moisture via condensation, etc., especially when the fan is installed above a sleeping area and the board cools to dew point at night. Spraying the electronics board with a couple coats of conformal electronics spray will waterproof it. There was an issue with some users finding condensation collecting in the bulb lens that covers the light on the inside control surface of the fan, which cause a short in the light. One fix is to drill a small hole in that lens so the condensation can drain out. I've also read that not all of these fans have that lens now, but mine did. Cheers!

Thanks for a nice short video which is not unnecessarily around 15 - 20 min for a simple fan to mount. Looks amazing specially the frame with the sealant.

This is probably the best channel I've seen for Conversions - most just gloss over everything but this is so SO detailed !!! Loved your detailed electrical video - it really answered a lot of my questions. Just subbed....

Love your videos and we’ve learned a ton and built our van to drive the Pan American. We ship to Cartegena on Monday! Doubtless you know, and I’m now experiencing, the Maxxair is sensitive to over voltage. I just purchased a regulator to help keep the power below the fans max voltage. Apparently, this is being exceeded by my battle born battery output. Just something to keep in mind. Lots of people have had this problem. I have the Deluxe 7500 bought in 2017. Worked fine until my new build changed a lot of the battery and charging system. Thanks for all the amazing content! Brian

Thank you for this video Nate! Thank you for all your videos. My entire electrical system was learned from you. I can’t thank you enough 🙏🏾

Your installation are very well executed, almost to an ocd type of level where every thing has to be impeccable. Thumbs way up!

Very nice work and thorough explanation.

Great video! When you do the electrical potion, you may want to address voltage issues some people have experienced. In particular, there is the general impression MaxxAir fans can be damaged by high battery charge voltages, so a "buck power converter" is installed to assure the fan doesn't get fried.

I just installed my Maxxair a couple weeks ago. Your install looks much cleaner, I wish I watched this first. I wanted to warn you, Maxxair fans tend to shut off unexpectedly. The specs don't say it, but tech support says that they have a voltage range of 10.6 - 13.6. If your system is 12V and you're charging your batteries up to the standard 14.4V for LifePO4 then the fan could have problems at the higher voltages. Most people use a DC-DC converter to keep it right at 12.0V.

Hi, great video! Thanks for helping with my installation:) just wondering, what is the fuse rating for this fan or what amp fuse did you use? I know most things should be rated 3x the amount of current draw but that requires measurment. The fan has an automatic resettable fuse but thought I'd wire it through one anyway (because of my dodgy wiring routing lol). Any advice will be greatly appreciated, thanks.

Hi, great video. I am a huge 'fan' (🤭, sorry) of the MaxxFan Deluxe. We have just patented a unique new shade system for it which adds AirMazeTechnology® and this keeps all light out but it allows full airflow (upto 100% Air In). Patented NiteAir® revolutionises hot sleeping by treating air and light differently for the first time.

Love your videos, great info 👍🏻👍🏻 Quick question, my E250 has a fiberglass top, do you think this fan can be mounted to my van? Thanks

Another great video! thanks

Did you use the 3M adhesive to the wood support below as well?

My buddy and I are following along on your channel and have pretty much got everything we need to get this Sprinter van on the camping program this summer. Have on question about Maxx Air 7500 installation: we are putting as much solar on the roof as possible and would like to move the panels as close to the fan shroud as possible without impeding air flow or getting in the way of its movements. Could we get 2" away from any part of the shroud and have a good safety margin for the above concerns? I have tried to contact Maxx Air by phone and using their website request form but no answer has come back. And we need to get this in so we can complete the solar and the interior ceiling. Nate, your suggestions/comments are greatly appreciated. Love what you do!!!

Excellent execution. Just a question: how many do or lap sealant tube did you use?

I would like to thank you mr. and Mrs. Yarbrough first of all for helping me become a little bit more independent as finish carpenter for 24 years and I injured my arm so I had to move into my RV I’m doing everything on my own and you guys probably help me more than anyone so thank you for that. I spent a summer in 2012 helping a friend he’s the lead solar technician of A company in chico over the years I’ve been fascinated with solar and hope we all can get to zero emissions someday! Since that summer I helped my friend I’ve been thinking and I came up with an idea that I would like to share with you if you wouldn’t mind an NDA agreement? I would be honored to share and propose some kind of arrangement with this intellectual property that I believe could change a huge part of this industry. It would be good in both residential commercial and mobile applications, and unless I’m a complete imbecile,? it should 100% increase wattage in any system, I’m not formally educated, but ever since I was a teenager I read about 1500 pages of seemingly arbitrary stuff per week. So anyway I guess self educated. I would love to at least have you hear my proposal and maybe with your expertise in this field you’ve heard of this already and I’m just a crackpot or I’m 30 years too late? Or perhaps someone thought of it and you can give me your admirably Colloquial direct response of why it’s just not feasible. Before my 20+ years in finish carpentry I worked at a Manufacturing (cnc machines and automated polishers) When I started as a young man we had six employees when I left there was 36 employees I was the manager of the night shift, I helped push the advancement and expertly came up with time saving procedures, so I have a basic understanding of what needs to be done on that side of it. My idea Has inherent risk and any simpleton would know that. But I am an absolute perfectionist and I believe that if we do things PERFECTLY…..not good….not really good…. But perfect! we can accomplish something amazing for consumers, Im willing to fund the R&D if it seems feasible to you. I’ve tried to email you guys a couple times I don’t know if you got them or if I’m doing it correctly not really good at Internet stuff but I sure make houses look beautiful

What should one do if the load (fan) is 5 metres away from the Source (battery?) Should one replace the black and white cable with 12awg to avoid voltage drop?

Love your videos, thank you. I’m in Australia and have bought the Unakagearco roof rack you designed, and the fan. As I have to import it, just wondering how many tubes of Dicor lap sealant did you use in total for the roof jobs?

Hello mate, I love your channel. There is one thing that I am always wondering - how is it with security when it comes to those fans - I see the fan from the outside. Would it be hard for a thief to jump on your roof, unscrew the fan and hop in to snatch your valuables when youre away?

What's the name of the black sealing compound you used

Wonderful video this week just like the rest, but I have 2 questions. 1. Why the wood support ring? Is it a weak place in the roof? I don’t remember you doing the same thing with the much larger air conditioner. 2. I know you need to wait for the ceiling for final measurements, but don’t you need to measure the large inside flange before you install the fan so it will fit correctly (since it’s built to be trimmed to different wall thicknesses)? I am going to assume that question will come up when you install it, but I thought it was measured before the fan went in, so I’m confused

I am curious as to why you went with a maxxfan in addition to the AC unit. Could the AC unit be used simply as a blower, and do away with the maxxfan? I believe the AC unit only draws a few amps on blower mode with the AC portion of the unit turned off.

Butyl tape width? 3/4” or 1”?

Did you use the single step primer for the window weld? Or did you not bother?

Have you experienced MaxxAir fan's inability to handle higher input voltage from LFP battery? I have a 2014 MY MaxxAir fan and it doesn't care if it receives 13.8v or 12.6v. But newer, circa 2020/2021 same model MaxxAir fans blow out the controller when fed with 13.8v. Known issue...some folks install voltage limiters at the fan as a workaround. Just curious if you've seen this issue.

i want to get the white one, but now it seems only smoke color is available. How much light does the smoke lid let through?

I'm sure that Nate already knows that the 'proper' way to hold the chisel is the other way around. However this works so it's not a big deal.

Waiting for a link on the outer flange!?

Were r u guys located

It’s just a fan and no AC or heat options?

Hey Nate, great video!! I've installed a few fans and I like to add 4 strips of aluminum (cut to fit, one for each side) on top of the fan where the screws go in so that it's tightening down evenly and not into just the plastic top piece. Does that make sense? Also, the Butyl tape should be one solid piece in stead of cutting them, this will help with possible leaks. The only seam should be in the back of the fan.

$80 for a plastic outer flange? Jeez... I'll stick to a thicker layer of sikaflex!

You need to buy 12v regulators for these otherwise your board will pop and you'll get the green light of death. these fans require an exact 12v or they will burn up over a very short period of time especially with lithium that can put out 14.5v.

Nate do you know if the maxair deluxe fans are still blowing motherboards when charging batteries...i.e when in absorption etc at 14.7v
