Elta Clearflow CF400 Three-Phase AC Roof Fan - 400mm

The Elta Clearflow CF400 Three‑Phase AC Roof Fan – 400mm is a commercial and industrial roof‑mounted centrifugal extraction fan designed for efficient vertical discharge ventilation. Part of the Clearflow CF series, it features a heavy‑duty pre‑galvanised steel casing and backward‑curved impeller for strong, reliable airflow with minimal maintenance. The vertical discharge directs exhaust air away from buildings, reducing odours and recirculation. Built for durability and performance with transformer speed control options available for stepped speed regulation, this three‑phase AC model is ideal for factories, warehouses, kitchens, and HVAC exhaust systems.
