gas handling fan

Gas handling fans are engineered to transport flue gases, exhaust streams, or process vapors that may be high-temperature, chemically aggressive, or dust-laden. Flow capacities range from 5,000 to 150,000 CFM at pressures up to 8 kPa.

Impellers and casings are fabricated from high-temperature alloys or corrosion-resistant materials, ensuring durability under thermal and chemical stress. Backward-curved or radial blades are balanced for smooth operation.

Variable frequency drives (VFDs) enable adaptive gas management, modulating fan speed based on upstream temperature and pressure sensors to maintain consistent flow and protect downstream equipment.

Maintenance is facilitated by split-casing design, sealed bearings with external grease fittings, and inline monitoring of vibration and motor temperature. Gas handling fans are vital for safe, efficient operation of furnaces, reactors, and boilers.
