8-39 series centrifugal induced draft fan
8-39 type strong cold fan is designed to ensure that the induced draft fan operates in the high-efficiency zone during variable working conditions, achieving energy-saving goals. It is a high-efficiency product organized by the Fan Energy-Saving Group of the Ministry of Machinery Industry, designed by leading experts in the national fan industry, and promoted by the State Economic and Trade Commission and the Ministry of Machinery Industry. The fan features high efficiency, low noise, and a wide high-efficiency zone, making it suitable for industrial boilers with a flow rate of 5 to 35 tons per hour. It is compatible with similar intake conditions and corresponding performance but should not exceed a maximum temperature of 250°C. A dust removal device with an efficiency of no less than 85% must be installed before the fan to reduce the dust content of the flue gas entering the fan. This not only reduces environmental pollution but also decreases the wear and tear on the fan caused by dust, thereby extending the fan’s service life.
Product Features:
①Capable of delivering higher gas pressure while providing more gas flow with low noise.
②Installation is very simple with the use of an integrated support frame, requiring minimal support from specialized technicians.
③The motor shaft is elastically connected to the drive shaft, eliminating the need for frequent belt tensioning or replacement, reducing maintenance workload.
④For fan systems with impeller diameters below 1400mm operating at normal temperatures, no additional bearing cooling device is required, reducing both user investment and maintenance workload.
⑤When airflow resistance increases, the motor load will automatically decrease, preventing motor burnout.
⑥Made of high-quality carbon steel, with options for stainless steel or other metal materials based on customer requirements.
⑦After production, the fan undergoes operational testing and vibration value detection to ensure reliable operation.
