Fantech inline Dryer Exhaust Duct Power Ventilators (DEDPV), (previously known as Dryer Boosters) are specially designed to solve 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 in the duct. Lint build up is a common cause of dryer fires.
When the dryer starts, Fantech's patented pressure sensing switch automatically turns on the DEDPV, which moves the warm, moist air and lint out of the home. The fan maintains a velocity of 1200 FPM to keep lint airborne and expelled.
