Best Fan-Tastic Roof Vent Cover Available For The Most Air Flow


You have given the open height as 11.5” but both the fantastic vent cover and the max air 2 covers are 10.25” height! Is the fan height adjustable?

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 the tallest covers available.

The best option cover for the most air flow is Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Cover # FVU1400GRS although it is still 10-1/4" tall it measures 23" long x 19-1/2" wide so it is longer than the standard covers to allow for better air flow.
