Model LB2 Dryer Duct Booster® Fan<br />
Enhances Safety, Energy Savings, Drying<br />
Times<br />
WHITE BEAR LAKE, Minn. — The level of safety and performance<br />
of residential clothes dryers has been raised thanks to<br />
the Model LB2 Dryer Duct Booster available from Tjernlund<br />
Products, Inc. The unique booster fan offers a 5-year no-clog<br />
guarantee, the potential of reducing clothes drying time up<br />
to 60 percent to save energy while incorporating features<br />
allowing it to be listed to the updated DEDPV, Dryer Exhaust<br />
Duct Power Ventilator supplement to UL705. The 2015 IRC<br />
restricts use of dryer booster fans to those tested to the<br />
DEDPV supplement.<br />
Adding dryer booster fans in clothes dryer ducts has increased<br />
substantially with the placement of laundry rooms<br />
not adjacent to outside walls. Duct runs often exceed 25<br />
equivalent feet (each elbow equates to five additional feet<br />
of duct length) that many manufacturers set as a maximum<br />
duct length. The Model LB2 booster fan is rated for duct<br />
lengths up to 150 equivalent feet. Reduces drying times and<br />
Tjerlund’s LB2 Dryer Duct Booster fan is rated for lengths up to 150 equivalent<br />
feet and can reduce drying times and energy consumption by up to<br />
60 percent.<br />
energy consumption up to 60 percent.<br />
The LB2 booster fan attaches easily to four-inch rigid or<br />
flex duct and plugs into an electrical outlet. A display panel<br />
mounted near the dryer confirms operational status and<br />
faults. It communicates via a factory-connected low voltage<br />
cable to an on-board booster fan control. The control monitors<br />
pressure and temperature within the duct to operate<br />
the booster fan in sync with the dryer and to stop booster<br />
fan operation if duct temperature exceeds 165°F or signal if<br />
the duct becomes blocked.<br />
Beyond the DEDPV compliant control system, heart of the<br />
LB2’s effectiveness is its exclusive no-clog lint handling<br />
blower design to eliminate regular cleaning of lint from the<br />
housing and blower wheel. This feature assures consistent<br />
booster fan performance with minimum maintenance. A<br />
demonstration of the LB2 fan’s ability to reject lint buildup<br />
can be seen online at http://www.dryerboosters.com.<br />
A rotating mounting bracket allows the LB2 booster to be<br />
installed vertically or horizontally. Rubber vibration mounts<br />
isolate the fan ensuring quiet operation.<br />
The LB2 DEDPV dryer booster fan is available through industrial,<br />
HVAC distributors and online.<br />
