Fantech DBF 4XLT Dryer Booster Kit w/FG 4XL Fan with wall mount indicator panel. Dryer Booster Kit with positive pressure switch and timed relay for long duct runs.
Dryer boosters are very similar to inline duct fans with one major difference: they are lint proof. Backwards inclined blades and an external motor virtually guarantees that no lint can interfere with the moving parts of the fan, ensuring that little to no maintenance is required. Used in longer dryer duct runs, Fantech Dryer Boosters are an excellent addition to any home laundry system.
