DESCRIPTION & PURPOSE
The LB2 is Listed to the updated DEDPV, Dryer Exhaust Duct Power Ventilator supplement to UL705 & CSA C22.2 #113-12. The 2015
IRC restricts the use of dryer booster fans to those tested to the DEDPV supplement. Incorporating dryer booster fans in clothes dryer
ducts has increased substantially with the placement of laundry rooms not adjacent to outside walls. Duct runs often exceed 25 equiva-
lent feet (each elbow equates to five additional feet of duct length) that many manufacturers set as a maximum duct length. The LB2
booster fan is rated for duct lengths up to 150 equivalent feet.
