Heavy Duty Axial Fan

In scenarios with near-critical ventilation reliability requirements - such as underground mines, tunnel construction, and power plant buildings - a heavy duty axial fan capable of delivering sustained, stable high airflow often determines the safety and productivity of the entire working environment. With 25 years of deep expertise in fan manufacturing, our factory has engineered this heavy duty axial fan as a flagship purpose-built product for high-load, long-cycle continuous operation. It employs a large-diameter airfoil impeller and a high-strength cylindrical housing structure, capable of generating tremendous axial thrust at relatively low rotational speeds, delivering air volumes ranging from tens of thousands to 100,000 cubic meters per hour while keeping vibration and operating noise at industry-leading levels.

Compared with ordinary axial fans, the heavy duty axial fan has undergone comprehensive upgrades in structural strength and environmental adaptability. The impeller is precision-welded from high-quality carbon structural steel or low-alloy high-strength steel, with blade profiles aerodynamically optimized; each unit undergoes dynamic balancing after assembly, with a balance accuracy no lower than Grade G6.3, ensuring smooth operation at high rotational speeds. The casing is roll-formed and welded from thickened steel plate, with both inner and outer surfaces treated with a dual anti-corrosion coating of epoxy zinc-rich primer plus topcoat, enabling it to withstand harsh industrial environments with high dust, high humidity, and mildly corrosive gases. The drive motor is a high-efficiency energy-saving three-phase asynchronous motor from a leading domestic brand, with IP55 protection rating and Class F insulation, capable of long-term continuous operation at ambient temperatures below 40°C. Our factory maintains an in-house R&D team, and every heavy duty axial fan undergoes full-parameter testing on a performance test bench and vibration spectrum analysis before leaving the factory, ensuring that key indicators such as airflow, pressure, and efficiency meet design requirements.

• Underground ventilation and heading face forced-air supply in metal and non-metal mines
• Longitudinal ventilation systems during construction and operation of highway and railway tunnels
• Ventilation and air exchange in boiler rooms, turbine halls, and coal conveyors of thermal power plants
• High-temperature fume extraction, spot cooling, and general building ventilation in metallurgical smelting workshops
• Air circulation and temperature/humidity regulation in large logistics warehouses and grain silos
• Ventilation system matching for ship engine rooms, ports and docks, and offshore engineering platforms

Our factory is located in Nantong, Jiangsu Province, at the core of the Yangtze River Delta economic circle, with comprehensive land, water, and air transportation networks. The factory covers over 10,000 square meters with more than 100 employees, equipped with advanced machinery including dynamic balancing machines, laser cutting machines, CNC bending machines, and CNC spinning machines, with a monthly production capacity of 5 million RMB. With 25 years focused on fan manufacturing, our product range covers eight major series with nearly 300 specifications, sold across 26 provinces and cities nationwide, with some products exported as matching equipment with main machinery.

From raw material receiving to finished product shipping, every production stage has dedicated quality inspection checkpoints. Steel plates, motors, and bearings are sourced only from qualified suppliers with material certificates. Welding is performed by certified welders, with critical welds undergoing spot penetrant testing. Each impeller is dynamically balanced after assembly with accuracy no lower than Grade G6.3. Before packaging, every unit undergoes 100% inspection covering five indicators: insulation resistance, grounding continuity, no-load current, vibration velocity, and noise - only units passing all tests are released. We also accept customer-designated third-party inspection agencies for on-site factory verification.

We have established a full-cycle service system covering pre-sales, during-sales, and after-sales. Pre-sales, technical consultants with over 10 years of experience provide one-on-one consultation, delivering selection proposals and drawings. During-sales, dedicated personnel follow up and regularly share production progress photos and videos. After-sales, all products come with a one-year warranty; manufacturing defects within the warranty period are repaired or replaced free of charge. Our dedicated team responds within 24 hours and provides solutions within 48 hours. For large-scale projects, on-site installation guidance and commissioning are available.
