Clearflow CFHT

The Elta Clearflow CFHT is a roof-mounted, vertical discharge centrifugal fan engineered to handle clean, grease-laden or contaminated air. With the motor positioned outside the airstream it supports airstream temperatures up to 120°C, and its vertical discharge projects odours and exhaust up and away from occupied areas — a strong choice for kitchen extract and hot process air discharged at roof level.

We offer all six sizes: 350mm, 400mm, 450mm, 500mm, 560mm and 630mm, delivering airflow up to 3.819 m³/s and static pressures up to 1,044 Pa via backward-curved blades.

• Can be mounted at angles up to 15° for direct installation on pitched roofs
• Wind guard fitted as standard to reduce noise and prevent unwanted draughts
• Pre-galvanised sheet steel casing with powder-coated steel impeller; robust all-metal construction with easy maintenance access
• Flange or foot-mounted IP55 motor with sealed bearings and Class F insulation
• Speed control and energy savings via Eltadrive VSD inverter
• Manufactured to ISO 5801, BS ISO 13347-1 and BS EN ISO 9001; 12-month warranty
