None 4 in. Dryer Exhaust Duct Power Ventilator Fan

Clothes dryers are often installed in areas of homes where they cannot work effectively leading to long drying times, high energy use, and lint buildup in duct-work. If a dryers exhaust duct run is over 25 equivalent feet moist air cannot effectively exit the dryer and exhaust to the outside bogging down the entire drying process. If a dryers exhaust duct run is over 25 equivalent feet and the dryer is experiencing long drying time, your dryer may need a Dryer Duct Booster fan. The Dryer Duct Booster can also reduce the potential fire hazard associated with lint buildup.
