4-72C Industrial Centrifugal Fan by China Suppliers | Versatile Factory Options Available

Our factory offers a diverse range of fan models with thirteen different machine numbers, including NO2.8, 3.2, 3.6, 4, 4.5, 5, 5.6, 6, 6.3, 7.1, 8, 10, and 1As a leading supplier in China, we ensure high-quality manufacturing and versatile product options.

These fans can be customized as either right-handed or left-handed configurations. The right cyclone model, designated as right, features an impeller that rotates clockwise, while the left cyclone model, marked as left, rotates counterclockwise.

The outlet position of the fan is adjustable, represented by the outlet angle of the casing. Our NO6-10 model is available with various configurations right out of our factory, allowing for installation in the desired position based on user specifications. The air outlet position can be adjusted from 0° to 225° in increments of 22.5° or 45°, providing six distinct outlet angles: 0°, 45°, 90°, 135°, 180°, and 225°. Additionally, the NO6-12 model can be tailored to directional angles as per customer needs.

We utilize a C-type transmission mode for our fans, ensuring efficient operation and durability. As trusted suppliers in China, we are committed to providing top-quality fans that meet your specific requirements.

    Frequently Asked Questions

    Q What do the model numbers (e.g., 2.8C, 3.2C, 12C) represent in the parameters table?
    The model numbers indicate the fan impeller diameter size in inches or centimeters, with the letter "C" denoting the centrifugal fan series. Larger model numbers correspond to larger fan sizes, higher airflow capacities, and typically higher power requirements.
    Q What voltage options are available for these centrifugal fans?
    All models listed in the parameters table support dual voltage operation at 220V and 380V, with a standard frequency of 50Hz. This makes them compatible with a wide range of industrial and commercial power supply systems across different regions.
    Q How do I select the right fan model based on airflow (traffic) requirements?
    To select the correct model, first determine your required airflow volume in m³/h and the system's total pressure in Pa. Then match these values to the Traffic (m³/h) and Total Pressure (Pa) columns in the parameters table. Each model offers a range of speeds and power options to suit varying application demands.
    Q What is the significance of the speed (r/min) values listed for each model?
    The speed (r/min) indicates the rotational speed of the fan impeller in revolutions per minute. Different speed options for the same model allow users to optimize performance — higher speeds generally deliver greater airflow and total pressure, while lower speeds offer quieter operation and reduced energy consumption.
    Q What is the difference between the Power (kW-P) and Horsepower (HP) columns?
    The Power (kW-P) column lists the motor's rated power in kilowatts along with the number of poles (e.g., "7.5-2" means 7.5 kW with a 2-pole motor). The Horsepower (HP) column provides the equivalent power rating in horsepower for reference, which is commonly used in certain markets and industries.
    Q Can these fans be used for high-pressure ventilation applications?
    Yes. Several models in this series are capable of delivering very high total pressures. For example, the 7.1C model at 1800 r/min can achieve total pressures up to 3134 Pa, and the 12C series reaches up to 2746 Pa. These specifications make them well-suited for demanding industrial ventilation, dust collection, and high-resistance duct systems.
