  • Comparison of MaxxAir MaxxFan "Mini Roof Vent and MaxxFan Roof Vent
  • The MaxxAir MaxxFan "Mini" Roof Vent w/ 12V Fan, # MA00-04401M and the MaxxFan Roof Vent w/ 12V Fan, # MA00A04401K are very similar but there is a difference in the profile. The MaxxAir Mini, # MA00-04401M will set at 2-7/8" above the roof when closed compared to 4-1/4" for the # MA00A04401K. The Mini will also work better with a thin roofed RV/Camper as it is compatible with roof thicknesses of down to only 1" where as the # MA00A04401K needs to have a roof at least 2" thick. Otherwise,...

  • Difference Between MaxxAir MaxxFan Mini Roof Vent and MaxxFan Roof Vent
  • The difference between the MaxxAir MaxxFan Mini Roof Vent # MA00-04401M and the MaxxFan Roof Vent # MA00A04401K does indeed simply have to do with its profile. The MaxxAir Mini Roof Vent will only extend 2-7/8 inches above the roof when it's closed compared to 4-1/4 inches on the standard model. The MaxxFan Mini will also work with a thinner RV/Camper roof as it is compatible with roof thicknesses of 1 inch to 6-1/2 inches (compared to 2 inches to 6-1/2 inches on the standard unit). As...

  • Comparing MaxxAir II and Fan-Tastic Vent Ultra Breeze Vent Covers
  • The MaxxAir II RV and Enclosed Trailer Roof Vent Cover # MA86JR and the Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Cover # DMC38FR have very similar dimensions so I doubt anyone would be able to notice any difference in actual ventilation performance from the 1-inch height difference between them. Since the USA-made MaxxAir # MA86JR is both lower in price and has twice as long a warranty (6 years vs. 3 years) I would go with the MaxxAir.

  • What is Difference Between MaxxAir II RV Vent Cover # MA26JR and # MA00-955003
  • The difference is that the MaxxAir II RV and Enclosed Trailer Roof Vent Cover # MA26JR is just the better all-around option over the MaxxAir FanMate Rain Cover # MA00-955003. It fits more vents, flows more air, and is priced better so it's the best choice.

  • Difference Between Fan-Tastic Vent Roof Vent # FV802250 and # FV801208
  • The Fan-Tastic Vent Roof Vent w/ 12V Fan # FV802250 and the Fan-Tastic Vent Roof Vent - Clamp On # FV801208 referenced in your question are indeed extremely similar to each other. These are both variable-speed, 12-volt roof vent fans designed for a rough opening size of 14-1/4 inch x 14-1/4 inch. As far as the units themselves, these products are virtually identical. The only real difference between the two models is the manner in which they install. The Fan-Tastic Vent Roof Vent - Clamp...

  • Difference Between MaxxAir Mini Deluxe Roof Vents # MA00-03851 and # MA00-03801
  • The MaxxAir Mini Deluxe Trailer Roof Vent w/ 12V Fan - Black # MA00-03851 and the MaxxAir Mini Deluxe - White # MA00-03801 that you referenced are indeed identical units except for their lid color. Both are 12V DC powered exhaust fans with 1 speed option and feature an integrated rain shield to prevent water from entering the RV or trailer. Any difference in price between the two options is simply related to manufacturer pricing and supply and demand. I have attached a video demonstration...

  • Which is Quieter the MaxxAir Trailer Roof Vent or the Fan-Tastic Vent Roof Vent
  • The MaxxAir vent # MA00-06401K and the Fan-Tastic Vent roof vent # FV801250 will be close to the same decibel level when running but I give a slight edge to the MaxxAir because it moves a little less air (900 cubic feet per minute versus 920 on the Fan-Tastic) and because it has a sealed ball bearing 12 volt motor which would theoretically be quieter. Honestly you may not be able to tell the difference. As far as wind noise on the exterior I would go with the MaxxAir vent again since it...

  • Comparing the MaxxFan 00-04500K and Fan-Tastic 803350
  • The MaxxFan Plus Roof Vent w/ 12V Fan part # MA00-04500K and the Fan-Tastic Vent Roof Vent w/ 12V Fan part # FV803350 are pretty much two different companies take on the same vent fan. They both have a powered lift dome, can be thermostatically controlled, and have a rain sensor. However they do have some key differences which I will point out for you below. You can then use these to see which vent fan would be a better fit for you. MaxxFan MA00-04500K Pros: - Dual Lifting Arms - 10...

  • Difference Between Fan-Tastic Trailer Roof Vent Covers
  • I believe you were referencing the Fan-Tastic Trailer Roof Vent Covers, though there isn't a 1600 model I was able to reference. There are 1500 models, though. The Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Cover # FVU1500WH (White) or # DMC38FR (Black) fit all Fan-Tastic Vent trailer roof vents. And to answer your second question, these covers will not interfere with the automated opening. They are designed so they will work perfectly with your automated vent opening.

  • Difference Between Fan-Tastic FVU1400GRS and FVU1500GR Fan-Tastic Vent Covers
  • The only difference is the roof vent models that each cover fits. The Fan-Tastic # FVU1500GR is meant to bolt right up to Fan-Tastic vents with part numbers beginning with "FA" or "FV". The # FVU1400GRS is meant for model number fans beginning with "DF". Either can be used with a standard sized 14-1/4 by 14-1/4 vent by either screwing it into the side of the vent or by using existing screws. The Camco # CAM40453 is more of a universal fit item, and wouldn't take advantage of the mounting...

  • Is This Fan Reversible?
  • The MaxxAir # MA00-04301M fan that you referenced is not reversible. It exhausts air only. However, the Fan-Tastic Roof Vent # FV802250 is reversible and has three speed levels and a tinted vent cover. If you don't already have one, most users install a Fan-Tastic # DMC38FR (in black) vent cover so the vent can be open in light to moderate rain. Use # FVU1500WH for white.

  • Comparing the Fan-Tastic Vent # FV802250 and the Clamp on Fan-Tastic Vent # FV801208
  • Both the Fan-Tastic Vent Roof with the Manual Lift # FV802250 and the Clamp on Fan-Tastic Vent Roof with the Manual Lift # FV801208 have a height of 4-1/2 inches when closed and a height of 11-1/2 inches when opened. Neither of them is higher or lower than the other when installed. The controls for the fan will be located at about the same height as well. The part # FV802250 has the deeper sides but that does not affect where the control is located. If you are looking for something a...

  • Differences Between Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Covers FVU1400GRS and FVU1500G
  • The difference between the Fan-Tastic Vent vent covers # FVU1400GRS and # FVU1500GR is in the models of vent that each one will fit, as you noted. Part # FVU1400GRS fits all Fan-Tastic Vent trailer roof vents with model numbers starting with "DF". Part # FVU1500GR fits all Fan-Tastic Vent trailer roof vents with model number starting with "FA" or "FV". You certainly can use your own preferred installation hardware. Both vent covers will also work with standard and powered vents from other...

  • Comparing Clamp on Fantastic Vent Fan # FV801208 to # FVFV802250
  • The Fan-Tastic Vent # FV801208 is a clamp on installation compared to the screw mounted installation of # FV802250. The other components of the vent fans are identical. Both require a sealant for installation but the clamp on FV801208 will have screws on the inside versus the screws on the outside. For just the sealant, I recommend # 0160297. If you use the more traditional mounting then I recommend the kit with sealant and screws # 344270KITW.

  • What is the Difference Between the 17-rpm Lift Motor for Fan-Tastic FVK6010-80 & FVK6010-81
  • The only difference between the Replacement 17-rpm Lift Motor for Fan-Tastic Vent B Series Roof Vents # FVK6010-80 and # FVK6010-81 is the color. The # FVK6010-80 is off-white and the # FVK6010-81 is white. These motors are designed for use in Fan-Tastic Vent roof vents with 17-rpm motors manufactured in 2014 or after. If your fan is of a lower rpm or manufactured before 2014, this motor will still work, but you will need to cross the wires. For example, instead of red to red and black...

  • Difference Between MaxxFan Deluxe Vents MA00-06401K & MA00-06200K
  • Sure thing; the MaxxFan Deluxe Roof Vent # MA00-06401K has only four speeds and does not have a thermostat so you have to manually set the air speed. The MaxxFan Deluxe Roof Vent # MA00-06200K has 10 speeds and includes a thermostat which will automatically turn the vent on and off based on the temperature, so it's a lot more convenient.

  • Difference Between The MaxxAir FanMate Vent Cover And The MaxxAir II Vent Cover
  • The MaxxAir FanMate vent cover Item # MA00-955001 is going to be just a little taller but the louvred end tapers in and it does not come with the screen which is Item # MA00-955202. 25" long x 18-1/8" wide x 10-1/4" tall. The MaxxAir II Item # MA76JR is a more lower profile design, and the louvred end is straight up and down. 22-1/16" long x 18-1/8" wide x 9-3/4" tall. This does not come with a bug screen, and unfortunately, there is not one designed for this vent cover. Each is also...
