Dryer Booster Duct Fan - Grainger

It helps your dryer run efficiently while removing the warm and moist air from the dryer duct. The fan should be added in the dryer duct run when the length of the run exceeds 40 feet with no bends, 35 feet with one bend or 30 feet with two bends. The fan can be used to effectively maintain dryer exhaust in duct runs up to 130 linear feet. The DBF 4XL features a pressure switch that automatically activates the exhaust fan once the dryer is on.
