The Maxxair Fan is a must have for weekend warriors to vans that are lived in full time, and everything in-between. The Maxxair fan is a fan, a vent, and a rain shield all in one! The fan and vent duo provides a breeze of fresh air inside the van, great for that fresh autumn air! With a built in insect screen there is no need to be worried about bugs being pulled into the van. Want some air circulation inside the van with outside air? The fan can be used without the vent for ceiling fan mode. All of this can be done no matter the weather conditions thanks to the build in rain guard! This deluxe version also features a thermostat to maintain your perfect temperature and offers a remote control electric opening.
