Tjernlund Products DB-2 Duct Booster
Professional-grade airflow solutions require hardware that stands up to static pressure. The Tjernlund Products DB-2 Duct Booster is a high-performance inline centrifugal fan designed to increase the delivery of conditioned air to poorly served branch ducts. Engineered for versatility, the DB-2 integrates into round ducts (5 to 8 inch) or rectangular ducts as shallow as 3.25 inches. With a peak capacity of 275 CFM, this unit effectively overcomes the resistance common in long duct runs or gravity-style systems. The 120V, 0.51 Amp motor is strategically positioned outside the airstream to ensure an extended service life and reliable operation in temperatures reaching up to 200°F. For technicians looking to automate airflow, this unit is compatible with the PS1503 Duct Airstat for pressure-sensing activation. Whether addressing "cold rooms" or boosting central AC delivery to a second floor, the DB-2 provides the high-volume airflow and HVAC ventilation efficiency required for modern residential and light commercial applications.
Key Benefits for Contractors:- Universal Compatibility: Mounts easily to 5", 6", 7", or 8" round ducts and works with rectangular trunk lines as shallow as 3.25 inches.
- Enhanced Thermal Durability: External motor mounting protects internal components from heat, making it suitable for high-temperature air handling up to 200°F.
- Installation Flexibility: Includes a mounting template and requires only a 4" x 7" cutout; attaches securely with four sheet metal screws.
- Performance Specs: Features a totally enclosed, permanently lubricated 1/70 HP motor running at 1550 RPM for quiet, consistent CFM boosting.
Can the DB-2 be used for combustion exhaust?
No, this unit is specifically designed for conditioned air circulation only. It must not be used to vent flue gases or combustible fumes.
Is this unit compatible with speed controllers?
Yes, the DB-2 supports variable speed operation when paired with a compatible 120V speed controller, allowing for precise airflow balancing in complex zones.
How should the motor be oriented during installation?
For optimal bearing life, the unit must be mounted so the motor shaft remains horizontal to the floor. It can be installed on the bottom of horizontal ducts or the side of vertical ducts.
