Description
The Elta Biflow SB is a bifurcated axial flow fan engineered for demanding high-temperature applications where the motor operates outside the airstream. Its conical or cylindrical design accommodates hostile air environments while maintaining reliable performance, making it ideal for industrial ventilation handling temperatures up to 200°C. The fan features adjustable pitch aerofoil impellers and robust all-metal construction with a hot dip galvanised casing for extended durability.
The range delivers efficient air movement across five standard sizes with air volume flow rates reaching 4.501 m³/s and static pressures up to 608 Pa. Class H motors isolated from contaminants and heated air significantly extend component lifespan, while the weather-resistant construction permits external mounting. Each unit is manufactured to BS EN ISO 9001 standards, undergoes rigorous testing to ISO 5801 and BS ISO 13347-1, and includes a 12-month warranty.
