VIVOSUN 6-Inch Inline Booster Duct Fan — 275 CFM with Speed Controller

Overview

Meet the VIVOSUN 6-Inch Inline Booster Duct Fan, a compact yet capable solution for moving air through tight spaces. With a 6-inch diameter, it delivers up to 275 CFM and spins around 3120 RPM to maintain steady ventilation where it matters. The robust steel housing and a motor designed with a permanently lubricated bearing contribute to a long‑lasting unit that operates with minimal attention.
