Unless you are a mad scientist or evil genius the chances you can control the weather are slim. You can however adapt and overcome a rainy day with a MaxxAir II vent cover. Even if the elements have forced you inside your RV you don’t have to deal with stale musty air, cooking odors, or smoke because the MaxxAir II vent cover is designed to allow your vents to stay open and provide ventilation even in the worst weather conditions. Odors escape and the rain stays out. Not every RV has the good fortune to be used full time; in fact most RVs spend the majority of their lives in storage. Leaving you vents open while in storage will help with the musty stored smell and it will also help prevent heat build up. Without a vent cover you may return to find debris, leaves, bugs, or water has made its way inside your RV.
MaxxAir II covers are made of high-density polyethylene with maximum UV protection, fit over most 14” x 14” standard roof vents, and provide twice as much vent area as the original. Like the original the brackets attach to the sidewall of the roof vent itself, eliminating the need to drill holes into the RV’s roof, but with the MaxxAir II the hardware is hinged for easy opening and cleaning. The MaxxAir II vent covers provide the same ventilation benefits in transit or parked. In transit the MaxxAir II cover also helps protect the lid of the roof vent from the wind generated by travel, which can destroy a vent lid.
The MaxxAir Original vent cover is not recommended for high powered ventilation fans. For high-powered fans the MaxxAir II or FanMate is recommended
