Fantech DBF110 Dryer Booster System. Fantech dryer booster fans are designed to eliminate the problems that can be caused by long duct work from your clothes dryer. Long stretches of duct work with multiple elbows can cause extended drying time as well as lint and moisture build-up within the dryer duct.
Originally dryers were designed to be located on an outer wall able to vented directly outside. Newer homes and condos are being designed so that the laundry is located on interior walls making it necessary to have extensive lengths of duct work to ventilate the dryer outside.
You will need a DBF110 Fantech Dryer Booster System when the length of your dryer duct work exceeds: 25 feet with no bends
20 feet with one bend
15 feet with two bends
10 feet with three bends
