Comparing MaxxAir II and MaxxAir FanMate Roof Vent Covers  

Updated 05/13/2026 | Published 03/21/2019

Question:

What is the difference between the maxair 2 and the maxair fan mate. I need 3 covers for my new Cougar fifth wheel and want to get the right ones. We have two manual vents and 1 that is controlled by incommand on our rv. They are all the same size on top. yes i climbed up their and checked in 30mph wind. lol

Aside from the MaxxAir II having inside dimensions of 21-1/2" long x 18-1/2" wide x 6" tall and the FanMate having inside dimensions of 26-1/2" long x 16-3/4" wide x 9-1/2" tall, the MaxxAir II comes with a bug screen but only 2 of the 4 mounting points use clips that can easily be removed. The FanMate doesn't come with a bug screen (but one can be added with part # MA00-955202 Black or # MA00-955203 Smoke) and it comes with 4 easily removable clips. I have attached video reviews for both options.

These covers come in a few different colors:

MaxxAir II
White - # MA00-933072
Black - # MA00-933075
Smoke - # MA00-955003

FanMate
White - # MA00-955001
Black - # MA00-955002
Smoke - # MA00-955003

If you plan on never removing your vent covers then I recommend going with the MaxxAir II as it will stay on those hinges and it comes with a bug screen but if you plan on removing your vent covers fairly often or you like the additional internal height at 9-1/2" then the FanMate is the better choice, especially since a bug screen can be added.

I have a MaxxAir fan that has 4 tabs on the outside with holes for a cover with clips. Does that mean the MaxxAir II with 2 hinges and 2 clips will not work with my MaxxAir fan? Thanks!

@Richard The MaxxAir II cover part # MA00-955003 has four tabs, two on each side, and comes with four clips to install it. What Jon was referencing is that when removing the cover for maintenance, it's harder on the MaxxAir II to remove all four clips, removing two on one side is easiest and then tilting the cover over. I've included a video showing one of our techs installing it where he talks about the four clips and opening it for maintenance.
