Fantech Fans clear the air in bathrooms and powder rooms with ease. The grille mounts in the ceiling while the fan motor mounts in a remote location away from the living area. The result is quiet yet powerful ventilation that is sure to protect your home from the damaging effects of moisture, steam and mold. While Fantech Dryer booster fans are specially designed to solve the problems caused by long duct runs on clothes dryers. Long duct runs with multiple elbows can cause extended drying time as well as lint and moisture build-up within the dryer duct.
