MAXXAIR I+ and MAXXAIR II are outside rain covers that sit above a compatible RV roof vent. They are not complete ventilation fans or replacement lids. Both protect an existing roof opening while letting air escape, but the two covers differ in the amount of ventilation they provide and the fan types Maxxair specifies for their use.

Existing roof flange
The installed roof vent stays in place; the cover is fitted around its exterior housing.
Original vent lid
Opens beneath the rain cover. Check that the lid and linkage clear the cover.
MAXXAIR I+ or II
The external shell and louvers provide weather protection while air exits.
Cover mounting hardware
The brackets attach at designated housing/flange points; installation method varies by cover and fan.
Component identification only; the manufacturer's separate illustrated instructions show actual mounting positions.
Do you have a high-powered ceiling fan?
For a MAXXFAN, Fan-Tastic or other high-powered rooftop fan, Maxxair recommends its FanMate cover to minimize airflow restriction. The MAXXAIR II may also work on some high-powered installations, but the manufacturer's recommended high-flow solution is FanMate. Compare your exact fan housing and mounting tabs before choosing a rain cover.
What to check on your RV roof
- Identify whether the installed 14 × 14-inch vent is non-powered, low-powered or high-powered. The same roof opening size does not mean the same ventilation requirements.
- Check room around the exterior vent, lid travel, solar panels, air conditioners and other roof equipment.
- Compare the roof mounting flange and any existing brackets to the chosen Maxxair instructions.
- Use the manufacturer's specified fasteners and sealing method. Do not block drainage gaps beneath the cover with sealant.
