Vents VS 450 EC Inline Fan - 17 3/4" - 4000 CFM

The Vents VS 450 EC Inline Centrifugal Fan delivers powerful, energy-efficient ventilation for demanding commercial and industrial applications. With airflow up to 4,000 CFM, its high-performance EC motor provides the capacity needed to ventilate large spaces while reducing energy consumption. Integrated variable speed control allows airflow to be adjusted to match ventilation requirements, helping optimize performance and operating costs. Engineered for durability and quiet operation, the VS 450 EC combines a corrosion-resistant galvanized steel housing with a backward-curved centrifugal impeller. This design delivers consistent airflow while minimizing operational noise, making it suitable for warehouses, manufacturing facilities, fitness centers, greenhouses, and other large commercial environments. Built around a robust aluminum frame, the fan features removable, double-skinned Aluzinc panels insulated with 20 mm of non-combustible mineral wool. This insulated construction helps reduce noise transmission and provides thermal protection, while the removable panels allow convenient access for inspection and maintenance. Combining high airflow capacity, energy-saving EC motor technology, and durable construction, the Vents VS 450 EC is designed for reliable, long-term commercial ventilation.
