Tjernlund Products EF-10 Duct Fan
The Tjernlund EF-10 Duct Fan is an industrial-grade axial duct booster engineered to increase airflow in problematic 10-inch branch ducts. Built for professional HVAC applications, this in-line duct fan features a 24-gauge galvanized steel housing with ribbed duct stops and crimped ends for a secure fit in both flexible and rigid metal ducting. Powered by a 1500 RPM shaded pole motor, it delivers a reliable 475 CFM airflow at 0.00" SP to resolve temperature imbalances in residential or commercial zones.
For precision system integration, the EF-10 is fully compatible with the SC-1 speed controller and can be automated using the PS1503 duct airstat to cycle with the primary air handler. The assembly includes an external junction box to streamline hardwiring. Designed for durability, the high-velocity duct booster handles air temperatures up to 150°F, making it suitable for both ambient supply and general exhaust runs.
Key Benefits
- Delivers 475 CFM airflow to eliminate hot or cold spots in long branch runs.
- Heavy-duty 24-gauge galvanized steel construction ensures structural integrity under pressure.
- Engineered for versatile mounting in both 10-inch flex and metal ducts.
- Speed controllable motor allows for fine-tuning of air delivery and acoustics.
- Rated for maximum inlet temperatures of 150°F for reliable HVAC performance.
Common Questions
How do I automate the Tjernlund EF-10 to turn on with my furnace?
Contractors typically wire the EF-10 in parallel with the furnace blower (120 VAC) or install a pressure-sensing switch like the Tjernlund PS1503 to activate the fan only when airflow is detected.
Can this fan be used in main trunk lines?
The EF-10 is optimized for branch ducts. For main supply lines or "trunk lines," larger models like the EF-12 or EF-14 are recommended to maintain sufficient static pressure.
Is the motor reversible for intake and exhaust?
While the motor direction is fixed, the unit is bi-directional based on installation orientation; simply flip the housing to switch between supply and exhaust configurations.
