MaxxAir Standard Installed Over Open MaxxFan

The MaxxAir standard vent cover installs 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 and allows smoke and stale air to escape, while also keeping rainwater and debris out. A removable bug screen behind the louvered area helps prevent insects from getting in. Zero-Leak brackets are included for installation.

Zero-Leak Mounting Kit

The Zero-Leak installation kit included with this vent cover prevents leaks by eliminating the need to drill into the roof of your RV or trailer.

Installed ZeroLeak Kit

Instead of mounting to your roof, this 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 Zero-Leak mounting brackets. These holes will be hidden underneath the vent cover once it is installed, where they will be protected from the elements.

If you are installing this vent cover over a Ventline E-Z Lift Ventadome roof vent, then drilling is not required. The E-Z Lift vent has mounting tabs with pre-drilled holes for installing the included hardware.

The kit comes with rustproof aluminum brackets and stainless steel screws, bolts, nuts, and washers.

Durable Construction

Durable Construction of MaxxAir Standard

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.

Video Transcript for MaxxAir MaxxFan Plus Manufacturer Review

Hi, I'm Mark Polk with RV Education 101. Today, we're going to install the most popular product ever designed to help with RV ventilation, the MaxxAir standard vent cover. The MaxxAir Vent Cover lets fresh air in your RV anytime, rain or shine, helping to prevent heat buildup and promote cross ventilation in your RV. It is designed to mount over all existing 14 x 14 inch roof bins and with the redesigned zero leak hardware kit it works on the new E-Z Lift Vent from Ventline too. Enough talking, let me show you how easy the MaxxAir Vent Cover is to easy stall. The E-Z Lift Vent by Ventline makes it easy to install MaxxAir Vent Cover. It has pre-drilled mounting locations for the redesigned zero leak brackets.

The first step is to place a carriage bolt, provided, upward thought the square slot in the one of the redesigned zero leak mounting brackets. Fasten the bracket to a pre-drilled location on the E-Z Lift Vent. Secure using a small screw, washer, lock washer, and hex nut provided. The hex nut should be placed on the inside of the mounting location. When all of the brackets are installed place the MaxxAir Vent Cover on the four upward pointing carriage bolts with the louver area facing the rear of the RV. Secure it using the star washers and hex nuts provided.

It may be necessary to push the head of the carriage bolt up into the bracket slot to prevent it from turning while you tighten the nuts. A slight air gap between the MaxxAir base and the roof of the RV is normal and helps condensation to escape. Do not apply caulking to this area. That's all there is to installing your standard MaxxAir Vent Cover. This super tough one piece design has withstood the test of time and is the only vent cover tough enough to come with a six year limited warranty.

The max air vent covers are the best. Easy installation and are screened which not only helps keep the bugs out but also helps stop the rain. Should keep the camping hauler a little cooler and drier. The tarp is just to keep the sun off. 564609

We needed some MaxxAirs for a new 5th wheel that we purchased. We knew from having them on a previous camper that they are good products. eTrailer has been a trustworthy place to order and get knowledgeable information from in the past. I had found a really good deal on the MaxxAirs at a different site, and contacted eTrailer. They stuck to their 110% price match policy and beat the other price. Quick shipping and good service on top of the best price. Can't beat it! 343886

It has continued to work well. Glad we we bought them...

After viewing the installation video and thoroughly reading the instructions the installation was a breeze. Had it done in an hour with the exception of having to go to the house to get a missing lock washer that was overlooked by the factory. Also the included flat washers were to large in circumfence so I had to replace them with smaller ones from my stash. The hood louvers deflect rain as advertised and the screen inside the hood repels bugs and dust. The hood mounts solid and the quality is awesome. I expect many years of dependable service and the price was great. I combined this hood order with a Max Air II and am satisfied with both. 283122

Thank you the new vent covers were easy to install and it went very well. Had all e done in 15 min. 646461

E-Trailer comes through again. I bought with confidence here after making a few previous and flawless purchases. This time the box was short one vent cover, a quick email with pictures of box and a phone call and my missing cover was on its way. Thanks for the quick painless resolution. As for the covers, plastic as most things these days but installed with confidence knowing they would do their job. Install was easy and straight forward even with my Lance 1575 "no walk on roof". Sat on edge and was able to do what needed to get done-center cover over vent, mark holes, drill holes, put brackets in place and bolt down. Easy as it gets and now fresh air in the rain is a crank turn or two away. The wife and I made a weekend of this and sealed roof while up there. Camping season, we are ready. Thanks E-trailer and MaxAir!! 497207

I received my order very quickly. Everything was great except the vent I wanted to cover was made of plastic. I could not bolt the brackets to it. I will have to drill holes in the roof to bolt the brackets down. I haven't made up my mind if I want holes in the roof. I may return the vent cover 706849

  • What is the Difference Between the MaxxAir and Camco RV Vent Covers
    Both the MaxxAir Standard RV and Trailer Roof Vent Cover part # MA00-933066 and the Camco RV and Enclosed Trailer Roof Vent Cover w/ Detachable Louvered Screen part # CAM40431 are designed to fit 14" x 14" roof vents. The overall dimensions of the MaxxAir is 19" long x 18-1/2" wide x 9-1/2" tall and the overall dimension of the Camco RV is 18-1/2" long x 18" wide x 9-1/2" tall.

  • How to Pick Out Replacement Hardware for Maxxair Vent Covers
    You didn't mention what kind of MaxxAir vent hood you bought, but if it matches the picture I attached in shape (not color as there are a few options), the hardwdare kit part # MA10A20115 that you referenced would be the correct kit. If instead you got the standard MaxxAir vent cover like the part # MA00-933066 you'd want the # MA00-225000.

  • MaxxAir Rain Cover Compatibility with Ventline # V-2094
    For your Ventline Ventadome, you will want the Replacement Dome Assembly for Ventline Ventadome Trailer Roof Vent # BVD0449-A01 or # BVD0449-A03 which is confirmed to fit your Ventline model. If you are looking for a rain cover compatible with this vent, I recommend the MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066. This will give you the mounting hardware and cover to allow use of your vent in less ideal weather. Since you don't have the factory mounting locations,...

  • Which MaxxAir Roof Vent Cover Fits Ventline Roof Vents # V2128sp-01 or # V2092sp-28
    The vent cover # MA00-933066 is designed to basically fit any roof vent so it would be the one to use with either the part # V2128sp-01 or # V2092sp-28 that you are wanting. The Camco Vent Cover part # CAM40431 is also an option that would work too. The part # MA00-933072 requires a MaxxAir roof vent since it has install brackets that match that roof vent so it would not be the correct part for you to use.

    The Replacement Lid for Ventline and Elixir RV Roof Vents part # CAM40161 measures 14-3/4" x 14-3/4" when measuring from the outside of each edge. I have attached a review video for you with these dimensions. That said, the Replacement Lid for Ventline and Elixir RV Roof Vent is designed to replace a lid not cover the actual lid.

  • Recommended Vent Cover for Ventline E-Z Lift Ventadome Trailer Roof Vent
    For the Ventline E-Z Lift Ventadome Trailer Roof Vent # V3092-601-00, I recommend the MaxxAir Standard RV and Trailer Roof Vent Cover - 19" x 18-1/2" x 9-1/2" - White # MA00-933066. This cover will allow for full vent function and also allow the vent to be open when traveling or camping in the rain. This is also available in smoke # MA00-933067. These covers will not require any additional mounting location but utilize the vent itself.

  • Will Fantastic Fan Vent Cover Replace MaxxAir Vent Cover
    The MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066 that you referenced will be an exact fit for the # FVU1500BL that you also referenced. These are designed to the same specs as they are both designed to fit the standard size RV roof vents.

  • Is the MaxxAir Mini Trailer Roof Vent # MA00-03700 Plastic or Metal
    The MaxxAir Mini Trailer Roof Vent # MA00-03700 that you referenced is made out of a durable plastic that actually does a really good job against the sun. If you wanted a total metal vent then you could use the Ventline Ventadome Trailer Roof Vent # V2110SP-24 which is also a manually operated vent. The thing about this kit though is that it will keep out bugs and debris when left open but not rain. To keep it open while it is raining you would need to use a cover like the MaxxAir Standard...

    While the MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066 isn't designed specifically to be hail resistant if you found yourself in a hail situation where the hail was big enough to damage the cover you'd also be damaging the roof of the trailer.

  • Picking Out Roof Vent for 2004 Alumascape Travel Trailer
    Most likely we have what you are looking for but you will need to first determine what vent you have on your trailer. The best way to find the correct replacement vent cover for your cargo trailer is to measure the vent. Most standard vents are 14-1/4 by 14-1/4 inches wide, 14 x 14 inches wide or 13 x 14 inches wide. Next if the manufacturer name is on the vent that will help. Finally, you will need to look closely at the hinged portion of the vent. If there is a rolled metal hinge...

  • Maxxair Vent Covers Compatible with Zero Leak Hardware Kit MA00-225000
    The MaxxAir Zero Leak Hardware Kit # MA00-225000 that you referenced is the only such kit we offer. It can be used with vent covers MA00-933066, MA00-933067, MA00-933068, or MA00-933069 which do vary slightly in size. Part # MA00-933066, for example, measures 19-1/2L x 18-1/2W while cover # MA00-933067 measures 18-3/4L x 19W Inch. I went to our warehouse to measure these brackets for you. They are 1-1/2-inches wide and the two ends of the "L" are 1-inch and 2-7/8-inches long.

  • Can Maxxair Roof Vent Cover MA00-933066 Fit Forest River R-Pod 178
    On the Forest River R-Pod 178s the center section of the roof is fairly flat so if a standard 14 x 14-inch roof vent is installed then you should not have any trouble installing a vent cover like the MaxxAir # MA00-933066. This cover attaches to the existing vent assembly, NOT to the trailer's actual roof surface, so you do not need to drill holes in the camper's roof. Slight curvature of the roof will not prevent installation since the cover connects to the existing vent. You can refer...

  • Availability of Replacement and Upgrade Parts for 2002 Holiday Rambler Alumascape Travel Trailer
    The series name for a travel trailer (and the specific trailer's VIN) are helpful when communicating with the trailer's original manufacturer but in terms of finding replacement parts you really do not need these. This is because most trailer makers do not maintain records of smaller component parts, such as wheel bearings for example, that are used in fabrication of their trailers. So finding replacements for worn items - or even upgrades - will just be a matter of telling us what you...

  • Replacement Ventline And MaxxAir Covers For RV Roof Vent
    Part # BV0554-03 is a smoke colored vent cover for Ventline old style rounded vents. You want to make sure the hinge on the # BV0554-03 matches the vent you have on your trailer. The covers we offer for the Maxxair standard vents are part # MA00-933067 for the smoke colored, and # MA00-933066 for white. As far as the smoke allowing in more light we have not been given those stats. The White cover is a more translucent cover and the smoke colored cover is a more transparent cover.

    If you are talking about a roof vent cover to help keep the rain out then I recommend going with the MaxxAir Standard RV and Trailer Roof Vent Cover # MA00-933066 because it is a universal application and mounts to the frame of your trailer roof vent. For a replacement lid you will simply need to note what kind of hinge your roof vent uses. For a continuous hinge I recommend the Ventline # BV0554-01, for a 3-point hinge I recommend the Ventmate # 69284, and for a 4-point hinge I recommend...
