Measurements of Mounting Points for MaxxAir II

Note: Some vents may not open fully when used with this vent cover. If opened 50% or more, the vent will still achieve maximum airflow.


Install this cover over your roof vent so that the vent can be opened and the fan can be operated in any weather. This prevents heat from building up inside your RV or trailer while keeping rainwater and debris out. The MaxxAir II has a large vent area that maximizes airflow and allows for cross-ventilation. And a removable bug screen behind the vent area helps prevent insects from getting in. Hinged brackets make it easy to open and close the cover for roof vent maintenance.


Large Vent Area and Side Louvers

MaxxAir II Large, Louvered Vent

The MaxxAir II has a vent area that is twice the size of the vent area on standard covers. This provides more airflow in and out of your RV or trailer. The angled louvers allow smoke, odors, and stale air to escape while keeping rain and debris out. And the louvers on the sides provide cross-ventilation for even more airflow.


Hinged Brackets for Easy Opening

MaxxAir II Cover Installed

The aluminum mounting brackets on the MaxxAir II are hinged. These hinges allow you to easily open and close the cover for cleaning and maintenance of your roof vent. No tools are needed. To open the cover, simply pull the snap-lock pins out of the brackets on one side of the cover. When maintenance is completed, close the cover and slide the pins into the hinges. Then push the pins down to lock them in place and secure the cover.


Installation

There's no need to drill into the roof of your trailer when installing the MaxxAir II because the vent cover mounts to the frame of your roof vent. Simply drill 4 holes into the vertical frame of your roof vent so that you can install the hinged mounting brackets. These holes will be hidden underneath the vent cover once it is installed, where they will be protected from the elements.


Stainless steel screws, nuts, and washers are included to install the cover over your roof vent. However, if you're installing this cover over a high-powered, 3-speed or 4-speed ventilation fan, use the included self-tapping screws to mount the cover instead.


Durable Construction

MaxxAir II Cover Installed

This vent cover is constructed of durable, high-density polyethylene. Special additives help ensure that the material can resist the negative effects of UV rays. And the cover is translucent so that some natural light can shine through.

This cover is a must have. I can leave my vent fan lid open 24/7 when parked or when i'm driving and rain still cant get in. Easy to install. Will be purchasing another one for my next trailer. Thanks ETrailer 749505

Great product so far. I leave my vent open and not seen any water get in.and it looks really good with my trailer.. 519612

by:

High quality and very well made. Fit was easy and works great. Part of a strategy to pull hot air out of the camper while sitting and moving down the highway to the camp site. Works well as the camper is cooler inside when I arrive. This is worth it alone, but also it keeps the room darker longer if the wife wants to sleep in, so that is great as well. Easy to flip open and clean the porthole cover as well. 572885

Have had these covers on another camper, I like the fact you can pull 2 pins and flip the cover off the vent to clean the vent cover, mine gets dusty and I clean the vent covers a couple times a year. etrailer did an awesome job boxing these up and protecting them during shipping, I really appreciate that. 504447

Great product easy to install. Wish I would have bought these sooner. The sun rotted my vent covers to brittle dust. Having these covers are also allow you to leave vents open during rainy and windy conditions also while driving. These are a must when owning an rv. 854193

When we purchased our new 40’ fifth wheel I ordered Maxair (4 total) and installed them post haste. We had them on our diesel pusher. Maxair is the best vent covers in production today. Really like the smoke grey. I should our reason to have them. Vent covers last for years and vents can’t be full open without rain arriving on your bed or floors, couldn’t be without the covers. 772174

Great product, great service! I made an order with several items in one and someone personally called me to let me know 1 item might take a little longer than expected to receive. I still got everything fast. I have 2 of these fans installed now. I have them set to automatically exhaust hot air in the summer when it is over 85 degrees in the camper, hoping to extend it's life, especially the adhesive in the floors, ceiling and wallpaper. 717712

  • Difference Between The MaxxAir FanMate Cover MA00-955003 and MaxxAir II RV Cover MA00-933075
    The MaxxAir Vent Covers part # MA00-933075 and part # MA00-955003 both are just used to cover the vent to protect it from the elements. However, the MaxxAir FanMate part # MA00-955003 is designed for the high power fan models because it does allow almost complete air flow. The vent cover is taller so it allows the fan to open almost completely and restricts only 5% of the air flow. The FanMate RV Vent Cover can be used on a standard fan as well but if you have a high powered fan this is...

If you have the flat mounting anchor points like in the other photo, then the MaxxAir II RV and Enclosed Trailer Roof Vent Cover - Black # MA00-933075 will work great.

  • MaxAir FanMate Rain Cover to Replace MaxxAir II that Won't Allow Full Vent Opening
    Since your vent cover goes up higher than the MaxxAir II RV and Enclosed Trailer Roof Vent Cover # MA00-933075 and you mention the motor on your fan, you most likely need to replace the cover with the MaxxAir FanMate Rain Cover - Smoke # MA00-955003 so you don't burn out your motor or damage your vent.

  • Will Black MaxxAir II RV Roof Vent Block Light Better Than the Smoke Vent
    The Black MaxxAir II RV and Enclosed Trailer Roof Vent Cover # MA00-933075 is a solid black. I went out to our warehouse with a flashlight to see how much light would pass through. Other than the vented part no light came through at all. Now, my flashlight isn't quite as bright as the sun but I'm confident it will block considerably more light than the Smoke, # MA00-933073

  • Comparing MaxxAir II and Fan-Tastic Vent Ultra Breeze Vent Covers
    The MaxxAir II RV and Enclosed Trailer Roof Vent Cover # MA00-933075 and the Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Cover # FVU1500BL 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 # MA00-933075 is both lower in price and has twice as long a warranty (6 years vs. 3 years) I would go with the MaxxAir.

  • MaxxAir Trailer Roof Vent Cover MA00-933075 for 2016 Forest River Sandpiper 381 RBOK 5th Wheel
    The MaxxAir II RV and Enclosed Trailer Roof Vent Cover # MA00-933075 is a great way to protect your RV interior from water and at the same time allow you to use the RV's standard-size 14 x 14-inch roof vent even in bad weather. The MaxxAir cover measures 22-1/8" long x 20-1/8" wide x 9-3/8" tall so it fits over any such roof vent and allows it to remain open. Based on my research your 2016 Forest River Sandpiper 381 RBOK 5th wheel uses the standard 14 x 14 vent so this MaxxAir cover...

  • Does MaxxAir Roof Vent Cover Allow Powered Roof Lid to Open Fully
    Since your RV has Maxxair roof vents already the vent cover you'd want is the part # MA00-933075 which was designed for this application. It won't allow the lid to fully open but once it reaches the top of the vent it won't continue to try and open. The vent will open far enough to allow max air flow while still preventing water from getting in or having to close it when travelling.

    Yes, the MaxxAir II RV and Enclosed Trailer Roof Vent Cover # MA00-933075 will fit the MaxxFan Plus Roof Vent # MA00-04500K. The reason that the vent cover is so much larger is that it is more of a universal style. If you would like a more custom fit then you need the MaxxAir FanMate Rain Cover # MA00-955002.

    To my knowledge, they do not make an enclosed roof vent cover that will allow your vent to open up completely. However, we do have the MaxxAir II RV and Enclosed Trailer Roof Vent Cover part # MA00-933072 for white or part # MA00-933075 for black that will allow your roof vent to open about 3/4" of the way. If the roof vent you have is automatic then it should have a built-in stop that would prevent the two covers from coming into contact with one another.
