Conquer the outdoors in comfort with help from a Coleman® Freestanding Tent Fan. This portable cooling tool gets the air circulating inside a tent and cools you anywhere at the campsite. The adjustable, two-speed fan will run up to 21 hours on four D-cell batteries. The soft, foam blades are safer for use around children, and when you’re done, the system folds up for compact storage. The fan is also perfect for keeping you cool on the patio, at picnics and at tailgate parties.
