Boost 400

Boost 400 (120V/60Hz) is Vents‑US’s largest Boost series inline mixed‑flow duct fan for 16‑inch round ducting. A redesigned mixed‑flow impeller and a polymer housing reinforced with a metal shell deliver high output with low noise. The 120V/60Hz single‑speed capacitor motor includes thermal overload protection and long‑life ball bearings rated up to 40,000 hours. At free air, the fan is rated up to 2112 CFM (≈3588 m³/h) with a published sound level of about 2.7 sones. The inline form factor simplifies installation and service, and the unit is suited to demanding exhaust or supply applications such as warehouses or greenhouses. Compatible with standard 16‑inch (Ø400 mm) round duct systems.
