Vents Boost 355 is a 14-inch (355 mm) inline mixed-flow duct fan for commercial and industrial ventilation. It delivers up to 1536 CFM (≈2611 m³/h) at 0" static pressure and operates on 120 V/60 Hz with a single-speed capacitor motor drawing 198 W. Sound is rated 2.6 sones. The housing is a durable polymer body reinforced with a metal shell, and the unit uses long-life ball bearings (up to 40,000 hours). The mixed-flow impeller supports higher pressure duct systems, and the in-line form factor simplifies installation and maintenance-free operation. Weight is 33 lb. Typical uses include warehouses, greenhouses, boiler rooms and workshops. An optional galvanized finger guard is offered for intake or exhaust protection.
