Many homes have damp basements that are stale， musty or smelly because of seasonal water issues， sump pits， floor drains or general lack of air exchange. The Xchanger Basement Fan is the economical and simple way to automatically ventilate your basement to eliminate basement odors and reduce humidity. Exhaust musty air or air contaminated by wood off-gassing or radon. Supply fresh make up air in tight homes or for stoves and fireplaces. Position one fan in each direction for balanced fresh air exchange. All three orientations exceed ASHRAE 62.2-2007 Ventilation Air Requirements. The X2D includes the fans and hood all in one compact unit. Includes de-humidistat control and magnetic draft stops to prevent unwanted air from entering your home. Install X2D through a 12 -1/4 in. x 5- 1/4 in. opening in a basement rim joist or any outside wall. Plug Xchanger fans into de-humidistat control and plug control into standard outlet. For less than the cost of a portable dehumidifier and at a fraction of the operating expense， reduce humidity levels and eliminate the musty smell of basement mold by installing a Tjernlund Xchanger basement exhaust and fresh air fan.
