Tjernlund Products EF-8 Duct Fan
The Tjernlund EF-8 Duct Fan is a performance-driven solution for addressing airflow deficiencies in residential and commercial 8-inch round ductwork. Engineered to deliver up to 325 CFM, this axial duct booster compensates for static pressure drops in long branch runs, ensuring consistent thermal distribution in hard-to-heat or cool areas. Constructed with a 24-gauge galvanized steel housing and a high-velocity aluminum prop fan, the EF-8 is built for durability and vertical or horizontal mounting flexibility in sheet metal or flexible ducting systems.
Operating on a standard 120V circuit with a 1.1 Amp draw, the EF-8 features a permanently lubricated C-frame motor rated for temperatures up to 150°F. For veteran contractors, this inline duct booster fan represents a reliable "set-and-forget" component when paired with the optional PS1503 Duct Airstat or SC-1 speed controller. Whether you are remediating a poorly balanced multi-zone system or installing a dedicated HVAC exhaust fan, the EF-8 provides the velocity needed to overcome resistance without the noise profile of traditional industrial blowers.
Key Benefits- Maximum Airflow Delivery: Rated at 325 CFM (free air) to effectively boost supply or exhaust velocity in 8-inch ducting.
- Rugged Construction: Features a corrosion-resistant galvanized steel housing and metal fan blades for long-term reliability in plenum environments.
- Flexible Installation: Compact 9-inch depth allows for easy integration into existing branch lines using standard duct clamps or foil tape.
- Low Energy Consumption: High-efficiency 56-watt motor minimizes operational costs while maximizing HVAC system efficiency.
- Broad Compatibility: Suitable for use in both warm air heating and central air conditioning systems with thermal protection up to 150°F.
- Can this fan be used for automatic operation? Yes. While the standard EF-8 is a plug-in unit, it is frequently paired with a pressure-sensing switch like the PS1503 to synchronize operation with the main furnace blower.
- Is the motor speed adjustable? Professional installers can utilize the SC-1 variable speed controller to fine-tune CFM output and minimize air noise at the register.
- Where should the fan be positioned in the run? For optimal efficiency and noise reduction, install the booster near the outlet end of the duct, but maintain at least 10 duct diameters from the register if using a pressure control.
