This durable, stainless steel, weatherproof solar powered ventilation fan is great for boats, vans, RVs, mobile homes, dog houses and more! Operates both in direct sunlight and at night with battery. NiMH battery will power fan for 48 hours with no sunlight. This solar vent extracts 680 cubic feet of air per hour under normal operation. For example, an RV that is 14 feet long, 5 1/2 feet wide and 6 feet high would take less than 45 minutes to completely change the air. Tips
To calculate the cubic feet of a space you wish to vent, multiply the length X width X height (in feet).
Then, to calculate the number of minutes it would take to completely change the air in that space you would divide the cubic feet by 680 and then multiply X 60. Comes with a gasket and installs in a 5" diameter opening. This is a smart pollution-free, environmentally conscious solution to venting and cooling many outdoor enclosed spaces with solar exposure.
