Fantech 12540 DBF 4XLT Dryer Booster Kit with FG 4XL Fan with Wall Mount Indicator Panel;

Fantech dryer booster fans have been specially designed to solve the problems caused by long duct runs on clothes dryers. According to dryer manufacturers and some local building codes, booster fans should be added in the dryer duct run when the length of the duct exceeds 24 feet with no bends, 20 feet with one bend or 15 feet with two bends. When the dryer is on, Fantech' s patented pressure sensing switch automatically turns the booster fan on. The warm, moist air in the dryer duct is exhausted out of the building quickly. The dryer booster fan monitors the status of the dryer and will turn itself off when the dryer stops. Wall-mounted indicator panel with LED display lets homeowners know that the fan is functioning properly.
