No, if you:

  • Just want to set your thermostat and forget it instead of turning your fan on and off
  • Like the clean look of a keypad to control your unit over a bulky knob

This Fan-Tastic Vent roof vent has a built-in 12V fan that circulates air inside your RV, camper, or enclosed trailer. Built-in hand knobs make it easy to open and close the dome, to adjust the fan speed, and to reverse the direction of airflow.

Ceiling Vent and Fan with 3 Speeds

Air out your RV after cooking or just draw in some fresh air while you sleep. Turn the speed knob on the vent housing to increase or decrease the fan speed. There are 3 speeds: low, medium, and high. This ceiling fan also allows you to control the direction of airflow with an additional knob.


This vent requires a 14-1/4" x 14-1/4" opening in your trailer's roof and ceiling. To replace an old vent, install this vent into the existing opening. If your roof does not already have a vent, you will need to mark and cut an opening between roof joists to install this unit. And the 2-wire design makes it easy to have your vent hooked up and ready for use.

easy to install works well deffinetly pulls and pushes air some noise but not bad should have put the remote controlled one in the shower for ease of reach 856622

- FV801250

Super easy install on a camper that did not originally have one. Quiet operation, and doesn't use much battery. 855696

- FV801250

I used this to replace the old vent (without fan) on our 1973 Prowler. I like how it fit right in and the wiring was a cinch. The smoke colored hood looks good too. 793078

- FV801250

this is the 3rd one of these we have bought from etrailer and put in our Airstream... (we needed 3) These are amazing. And shipping was even more amazing! and they look great 775135

- FV801250

Easily navigated website with clear descriptions. Prices are comparable and fair. Wide range of products and lots of tips for usage. Purchased LED light strips and a Fantastic Fan. Shipping was fast and efficient. Refurbishing a 1965 Avion C10 camper - nuance is important and products we purchased fit the bill! 775431

- FV801250

Exactly what we needed. Works perfectly. I was having to walk around our pop up camper poking the canvas with a broom handle as he was lowering the top slowly by the hand crank. Now he just turns the fan on and the canvas pulls in like magic! We love it! 771985

- FV801250

I've ordered several products from etrailer.com and the service and shipping have always been excellent. This particular vent fan is great. I run it off of solar and it hardly takes any juice. It is definitely a strong fan and the reversible function is great to have. I'd purchase again for sure. 769954

- FV801250

shipping was very quick and free! Liked the completeness of this product. New mounting screws and ceiling garnish for inside the camper. 751536

- FV801250

Will not install until later in year. So far I have no complaints. 749888

- FV801250

Product arrived promptly. I’m taking top air conditioner out which don’t work and replacing it with the exhaust reversable fan. Item looks great but I haven’t installed yet because of rain. I also got led which are great. Still waiting on a confirmation of second order 747461

- FV801250

I like to have things I can control, and this fan is manually controlled. It doesn't look for a certain temperature and rain etc. Turn it on and it runs - which is why I bought this model. It doesn't think it knows better me if I want it to run or not, unlike other fans in my motor home. Not 5 stars because I believe the motor produces more noise than it should. I really believe the motor could be manufactured to make less noise. 746371

- FV801250

Great fan, but it could be better! It really sucks the air right out (or in) quickly and that part is fantastic. However, this fan is quite loud and for this reason I seldomly leave it on overnight as it is just too disturbing. Also, the plastic housing is a type of plastic that is not compatible with quite a few sealants, so do your homework first before you install as I had to install twice as the first time it leaked after using OSI QUAD Max - which is not compatible. 739147

- FV801250

Recieved promptly and item was exactly as listed. Nice fan. Quiet, great features. 733610

- FV801250

Pros: Product matched description and shipped in a timely manner/in adequate packaging. Documentation was provided. Excellent customer service from etrailer Cons: Necessary fasteners were not included and had to be purchased separately. Trim was flimsy and felt cheap, necessitating additional labor and materials to construct a suitable functional replacement. 725141

- FV801250

Great product! Quality is great! Installed easily and works flawlessly. Circulates the air better than I expected! Not as noisy as I thought it might be. Very happy with the fan. 724849

- FV801250

One year installed and still going without any problems. It even withstood an attempted break-in by raccoon while I had the vehicle in storage. Easy to install and wire. I like the reverse airflow feature. Highly recommend this product. 722729

- FV801250

Exelente fan! 720785

- FV801250

This ceiling fan really pushes/pulls some air. Our smoke alarm constantly went off any time we’d cook with the orig fan, but not any more. Also, being able to reverse the air flow is a nice feature too. 707057

- FV801250

Great fan cooled down my bus by a few degrees moves a lot of air 704689

- FV801250

This works as advertised. The installation was much easier than I expected. After watching a couple of Youtube videos on installing this went in very easily. 703226

Ask the Experts about this Fantastic Vent RV Vents and Fans

  • What Is The Difference Between The Fan-Tastic Roof Vents FV801250 and FV801350
    You have asked a great question. The difference between Fan-Tastic Vent Roof Vent part # FV801250 and Fan-Tastic Vent Roof Vent part # FV801350 is the garnish. The garnish (or base) that comes with the vent part # FV801250 is 4 inches thick compared to the garnish (or base) that comes with the vent part # FV801350 is a low profile 1-1/2 inches thick. The FV801250 fits trailers roofs up to 4 inches thick and FV801350 is better for thin roofs like enclosed trailers with thin metal roofs....

  • Replacement Motor Assembly for Fan-Tastic Roof Vent With 12V Fan
    It sounds like you have Fan-Tastic Vent Roof Vent # FV801250, which has reverse flow, a 3-speed fan and no rain detector. If this is your fan you need the Replacement Fan Motor Assembly Kit for Fan-Tastic Vent Roof Vent Fans # FVK8017-00, which replaces the bow-tie bracket, motor, and blade for your vent.

  • Installation and Wiring of Trailer Roof Vent with 12V Reversible Fan
    The Fan-Tastic Vent Roof Vent w/ 12V Fan - Reversible # FV801250 will fit in the same opening as your current vent as they are industry standard size. I recommend using the Installation Kit # 344270KITW to install and seal your vent. You can run wires directly to your trailer battery or into the same circuit breaker as your lights using # 16-1-1. That will allow you to use your fan and have the lights off versus just splicing into the light power. The motor will draw 36 watts and...

  • Does Fan for Fan-Tastic Roof Vent Automatically Shut Off When Cover is Closed
    The Fan-Tastic Vent Roof Vent w/ 12V Fan # FV801250 has a built-in feature that automatically shuts off the fan when the lid is closed. When you open it the fan should turn back on if the power switch is in the "on" position. I reached out to my contact at Fan-Tastic Vent who confirmed this for me and I also clipped part of the instructions for you to check out.

  • Availability of Replacement Triangular Motor Knob for Fan-Tastic Vent
    I reached out to my contact at Fan-Tastic Vent and he was able to identify the specific model vent you have, which uses the triangular motor with the thumb slide and knob. Unfortunately this particular knob/motor is no longer produced, You might have luck finding a used part, and for reference the actual part number for the knob you need is K6055-81. Otherwise your only option is to replace the entire vent assembly with a new/current model. This is probably the best solution too since...

  • Replacement Vent For Northern Breeze Trailer Vent V2525-01-S46-M
    I do have an option for you but you have a Northern Breeze Trailer Roof Vent part # V2525-01-S46-M and the replacement lid part # BVB0568-01 which has been discontinued. I was not able to find that particular lid anywhere else either. I recommend to replace the entire roof vent with Fan-Tastic Vent Roof Vent w/ 12V Fan - Reversible part # FV801250 which will fit the same cut out as your old Ventline Northern Breeze. I recommend to just replace it with a modern version because it is really...

  • Can the Fan-Tastic Vent Roof Vent with 12V Fan be Used in Bathroom
    The Fan-Tastic Vent Roof Vent with 12V Fan # FV801250 that you referenced will work well for you in your camper bathroom. This vent's 12V fan is reversible to pull in fresh air or push out stale air. The fan also offers 3 speed to adjust airflow as needed. The dome filters out UV rays while still allowing light in, and a hand-operated knob allows you to open and close the dome as needed. The # FV801250 fits a rough opening size of 14-1/4 inches x 14-1/4 inches and will fit RV, camper,...

  • Replacement for Northern Breeze Roof Vent on a 2004 Holiday Alumascape
    Since the guts of a roof vent aren't really interchangeable between manufacturers and the Northern Breeze line from Ventline is discontinued I recommend replacing your entire vent with the Fan-Tastic Vent Roof Vent w/ 12V Fan # FV801250. This vent features a manual operated lid, a reversible 12V fan, and no automatic settings. It will fit in the same cutout dimensions from your older vent and comes with a 4" thick garnish so you get that new install look. I have attached a review video...

  • Replacement Vent for Ventline Northern Breeze Model V2501 with Bad Circuit Board
    Any circuit boards included in a fan would definitely be brand and/or model specific so I checked with Ventline for a replacement for the board in your Northern Breeze V2501 fan. Unfortunately, Ventline no longer has stock of those circuit boards. So, a new fan is in your future and we can help. You can use the linked page to see all roof vents from Ventline and others.

  • Troubleshooting Fan-Tastic Reversible Roof Vent FV801250 That Squeaks in One Direction
    My first thought concerning the vent fan being squeaky in only one operating direction is that dust may have found its way into the unit during/after the interior refurbishment process. I am only speculating here, but if for example the fan were operated in outgoing/exhaust mode during the refurb process (when surfaces were being sanded, for example) it could have pulled in material that is causing the noise. The workers might have done this to keep the MH interior as clean as possible...

  • Height Dimension of Fan-Tastic Vent 12V Reversible Fan RV Roof Vent FV801250
    The Fan-Tastic Vent 12V Reversible Fan RV Roof Vent # FV801250 operates in both directions with a 920-CFM (cubic-feet-per-minute) air volume. I went to our warehouse to measure the height of the fan assembly without the lid's height included. I found this to be 2-1/2-inches, measured from the top of the flexible rubber gasket to the bottom surface of the mounting flange, which is what will contact the surface where you install it.

  • Do Roof Vent Garnishes Have to Match Thickness of Trailer Roof
    The height of the garnish that comes with the Fantastic Vent part # FV807350 is designed for up to 4 inch thick roofs. It can still be used on a ceiling that is 5 inches thick, but there would be a 1 inch thick area between the top of the garnish and where it meets the fan body. We do not offer a larger garnish that would fit.

  • Location of 12V Power Wiring in RV for Installing Fan-Powered Roof Vent
    Unfortunately we have no way to predict the presence or specific location of wiring in any given RV for installation of a fan-powered roof vent such as the Fan-Tastic Vent 12V model # FV801250. You may have success by contacting the RV maker with the unit's VIN. Sometimes RV makers will install certain wiring or other features on all production of their RVs in case customers wish to have a local dealership install an optional item. It is much easier to install this wiring at the factory...

  • How to Determine Model Number of Fan-Tastic Vent
    Have you checked the inside of your Fan-Tastic vent to try and find the model number? If you take a look at the accompanying photo that one of our customers sent in you can see the model number was on the fan blade but it might be elsewhere internally on your vent so you may have to use a flashlight and look hard or take it apart to truly find out. As for replacement parts I would need to know the model number of your fan in order to get you correct parts.

  • How to Make an RV Roof Fan Run in the Opposite Direction
    It depends on the fan and its design. Some fans cannot be reversed. Most RV fans can be reversed by switching the polarity or essentially wiring it backwards. Another possible option is you can flip the fan blade itself over and the blades will move the air in the opposite direction. Some fans are designed to be reversible so all you need to do is flip a switch, like # FV801250.

  • Recommended Trailer Roof Vent with 12V Fan
    We do have a wide array of roof vents with 12V fans available for trailers. The most common square-shape trailer roof vent measurement is 14 x 14 inches, and this is the closest that we have to the 13 x 13 measurement that you made. If this happens to work, I recommend the Fan-Tastic Vent Roof Vent w/ 12V Fan # FV801250. This has a variable-speed 12-volt fan that has a simple 2-wire installation. I have attached a video review of this product for you to look at. I have also included...

  • Can Fan-Tastic Vent Roof Vent w/ 12V Fan # FV801250 Work with Vent Lid Cover
    Sounds like you have a cover for your current RV roof vent made by the company Ventmate. These covers like the # FVU1500BL allow the vent lid to open far enough to all full air flow but also cover the opening so that rain doesn't leak in. The fan of the # FV801250 would still be just as effective.

  • Best Tool to Use for Trimming Garnish for RV Roof Vent
    A rotary tool would work best for trimming the garnish on your RV roof vent, like the Fan-Tastic Vent Roof Vent # FV801250. If you don't have a rotary tool then you could likely use something like tin snips (heavy duty scissors) instead. It would be beneficial to smooth off anything you cut with something like sand paper or a smaller file just so that if you ever need to remove the garnish for repairs that's one less thing you have to think about.

  • Height of Fan-Tastic Vent Trailer Roof Vent FV801250
    The Fan-Tastic Vent Roof Vent # FV801250 will extend above your trailer roof surface by 4-1/2-inches when closed. When open the top edge will be 11-1/2-inches above the roof.

  • Best Fan-Tastic Roof Vent Cover Available For The Most Air Flow
    You are correct the Fan-Tastic Vent Roof Vent w/ 12V Fan - Reversible part # FV801250 is 11-1/2" when open. The Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Cover part # FVU1500BL MaxxAir FanMate part # MA00-955003 are both 10-1/4" tall. I have contacted Fan-Tastic vent about this and they assured me that the shorter cover will not effect the functionality of the fan or the motor at all even though the fan will not completely open. The fan height is not adjustable and 10-1/4" tall is...

  • What Size Fuse is Used for the Fan-Tastic Vent Roof Vent # FV801250
    The fuse for the Fan-Tastic Vent Roof Vent # FV801250 is a 4 amp fuse. If you were wanting to use an in-line fuse holder then the part # C58470-1 can handle up to 10 amps so it would work well with a 4 amp fuse.

  • Replacement Motor Gear for RV Bathroom Roof Vent
    The only replacement motor gear we have available for RV roof vents is the Ventline # BVD0121-00. This fits the Ventline Ventadome model V2119 and is the gear that transfers power from the motor to the operator for opening and closing the vent. If this is what you have then the gear will work perfectly. I was unable to cross-reference the numbers you found on the gear motor with any of the parts that we have available.

  • Replacement Trailer Roof Vent that Measures 12 Inches by 12 Inches
    The 14 by 14 inch measurement is the opening that the vent fits into in the roof. So if your opening is 12 by 12 inches it doesn't sound like we have a lid that will work for you. If you're looking to replace the entire vent then you can increase the size of the hole and use a vent like # FV801250.
