4-79 series centrifugal induced draft fan
The 4-79 series centrifugal induced draft fan is used for indoor ventilation and air exchange in general factories and large buildings. It can be used for both intake and exhaust of gases. The gases transported include air and other non-combustible, non-explosive, non-corrosive, and non-harmful gases to human bodies and steel materials. It can also be made into explosion-proof and flame-retardant types according to usage requirements, suitable for environments with flammable, explosive, or corrosive gases. The gas must not contain viscous substances, and the dust and hard particles must not exceed 150mg/m³. The gas temperature should not exceed 80°C, and gases with similar characteristics can also be used. This fan is widely used for ventilation and air exchange, cooling, and dust removal in factories, mines, stadiums, theaters, basements, large and small hotels, restaurants, shopping malls, and large buildings. It can also be used in conjunction with other mechanical equipment for gas circulation, mainly transporting air and other non-combustible, non-explosive, non-harmful, and non-corrosive gases to steel.
Product Features:
①Can output a large gas flow while meeting pressure requirements, with low noise.
②V-belt drive allows the fan to operate at the most suitable speed. Simple installation, requiring no professional technical support.
③Airflow channels and impellers are optimized multiple times, achieving higher efficiency and energy savings compared to standard large flow fans.
④Made of high-quality carbon steel; stainless steel or other metal materials can be used upon user request.
⑤The impeller is annealed to completely eliminate the internal stress generated during welding, ensuring that the impeller will not undergo shape creepage or crack.
⑥All units are subjected to operational testing and vibration value checks after production, ensuring reliable operation.
⑦Simple installation, requiring no professional technical support.
