The blades and guide vanes of Ruidong draught fans are made using a one-time die-press forming process, ensuring structural integrity and aesthetic appeal. The impeller is welded using robotic welding technology and undergoes dynamic and static balance testing, ensuring stable operation, effectively reducing vibration, and extending the fan’s service life. The gap between the impeller and the casing is controlled to be very small, less than 0.5% of the impeller diameter, which significantly reduces air leakage and improves the fan’s energy efficiency.
The assembly-type motor bracket design reduces welding, making the fan not only more visually appealing but also easier to disassemble and maintain, improving maintenance convenience. Ruidong fans use H-class motors and YE3 F-class insulation motors, ensuring high-efficiency operation and long-term stable performance.
