Description
The Tjernlund Products EF-10 Duct Booster Fan is an inline fan used to improve airflow through duct runs, balance air distribution in HVAC systems where certain areas receive reduced supply. Built for 10-inch flex or metal ducts, it moves air by using a motor-driven blade assembly that increases flow through the duct section. This allows better delivery of conditioned air to distant or restricted spaces. Mounted directly within the duct line, it is secured between duct connections and wired to the power source during setup, contributing to more consistent airflow and improved comfort across the system.
