Dry your clothes up to 50% faster and prevent lint build up with the new Dryer Duct Booster.

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 ductwork. If a dryer’s 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 dryer’s 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 LB1 Dryer Duct Booster Fan surpasses all existing dryer duct fans with features including:

• The LB1 Lint Blitzer™ impeller. Unlike traditional in-line fans which can clog
  with lint, the Lint Blitzer™ impeller is designed to repel lint while providing optimum velocity.

• 5 year no clog, no maintenance guarantee.

• Saves energy by turning on and off with the dryer.

• Permanently lubricated motor positioned out of the air stream for maximum motor life.

• Simple installation in both vertical and horizontal ducts.

The Dryer Duct Booster fan maintains proper exhaust velocities in duct runs up to 100 equivalent feet, optimizing dryer performance.

* For equivalent feet 90º elbows equal 5 feet and 45º elbows equal 2.5 feet.
