Engineered for demanding commercial and industrial ventilation applications, the Vents Boost 355 Inline Mixed Flow Duct Fan delivers powerful, high-volume air movement in a compact, durable design. Featuring a 14-inch round duct connection and airflow capacity of up to 1,536 CFM, the Boost 355 is designed for ventilation systems requiring reliable air extraction, air circulation and continuous performance.

At the heart of the Boost 355 is a newly engineered mixed-flow impeller that combines the airflow characteristics of axial and centrifugal fan technology. Its reinforced polymer and metal housing provides a robust construction, while the single-speed capacitor motor incorporates thermal overload protection for dependable operation.

Designed for straightforward integration into standard 14-inch round ductwork, the Boost 355 is suitable for both new commercial ventilation installations and upgrades to existing systems. Need a 16" Boost fan with 2112 CFM? click here.
