Elta Clearflow CFHT400 400mm Three-Phase AC Roof Fan

The Elta Clearflow CFHT400 Three‑Phase AC Roof Fan – 400 mm is a heavy‑duty, roof‑mounted centrifugal fan engineered for demanding industrial and commercial HVAC applications. Part of Elta’s high‑temperature Clearflow CFHT series, it combines a durable pre‑galvanised steel casing with a backward‑curved impeller to deliver powerful vertical discharge airflow. Designed for continuous duty in harsh environments—including contaminated or grease‑laden airstreams—this model supports elevated temperature operation up to +120 °C and can be mounted at pitched roof angles up to 15° for flexible installation. High‑performance three‑phase AC power ensures consistent, reliable ventilation for factories, process areas, kitchens, and large ventilation networks.

Material & Build Quality

• Pre‑galvanised sheet steel casing for rugged durability and corrosion resistance.

• Backward‑curved centrifugal impeller optimised for strong, efficient airflow.

• Motors located outside the airstream to resist contaminates and extend service life.

• Standard wind guard fitted to reduce noise and draughts.
