Fantech Dryer Exhaust

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.

When is a dryer booster fan necessary? According to some dryer installation instructions and local building codes, booster fans should be added in the dryer duct run when the length of the duct exceeds 25 feet with no bends, 20 feet with one bend or 15 feet with two bends.

How do they work? When the dryer is on, Fantech’s patented pressure sensing switch automatically turns the booster fan on to move the warm, moist air in the dryer duct out of the home quickly.
