Tjernlund Products LB2 Duct Booster
The Tjernlund Products LB2 Dryer Duct Booster is a professional-grade solution engineered to maintain optimal exhaust velocity in 4-inch rigid metal ductwork, supporting vent runs up to 150 equivalent feet. This DEDPV (Dryer Exhaust Duct Power Ventilator) compliant fan solves performance issues in complex laundry configurations where equivalent feet exceed the 25-foot limit standard for most residential dryers. Featuring a Lint Blitzer material handling wheel, the LB2 utilizes a reverse-inclined impeller designed to prevent lint accumulation, while the PSC motor is positioned outside the airflow to protect it from moisture and heat. The system includes an on-board micro-controller that synchronizes with the dryer’s cycles via pressure and temperature sensors. A dedicated safety circuit with a redundant high-limit sensor monitors for duct restrictions or excessive temperatures, communicating through a remote status panel to alert contractors or homeowners of potential dryer fire hazards or mechanical failures.
- DEDPV Certified Performance: Fully compliant with 2015 IRC requirements and UL705 standards for safe dryer exhaust ventilation.
- Enhanced Airflow Management: Maintains critical dryer exhaust velocity across extended long duct runs to reduce drying time by up to 50%.
- Vibration Isolation: Equipped with a 360-degree rotating, rubber-isolated mounting bracket to eliminate noise transfer and facilitate flexible installation.
- Intelligent Control: Automatic operation through high-resolution sensors and a remote monitoring panel for real-time status updates.
- Direct Drive Compatibility: Suitable for both gas and electric 4-inch residential dryer installations.
Common Questions
Does this unit require a secondary lint trap?
While the Tjernlund LB2 is designed with a no-clog impeller, installation within 15 equivalent feet of the dryer often requires the Tjernlund LT4 secondary lint trap to protect the booster and downstream ductwork from excessive lint loading.
How do you calculate equivalent feet for this booster fan?
When sizing for HVAC duct boosters, calculate total linear feet and add 5 equivalent feet for every 90° elbow and 2.5 feet for every 45° elbow to ensure the system does not exceed the 150-foot rating.
Can the LB2 be mounted vertically?
Yes, the LB2 Dryer Duct Booster is designed for horizontal or vertical mounting; however, vertical orientations must discharge facing upward to ensure proper flapper operation and prevent debris fall-back.
