High Efficiency 9-19A High Pressure Centrifugal Fan from China Suppliers and Factory for Industrial Applications

,

The 9-19A high-pressure centrifugal fan is a top choice among fans made in China, offering superior efficiency, low noise levels, and a flat performance curve that enhances its operational range. This centrifugal fan is designed to cater to various industrial applications, particularly in forging furnaces and high-pressure ventilation systems.

,

As reliable suppliers of high-quality fans, we ensure that this model is adept at material transportation and is suitable for conveying air as well as non-corrosive, non-viscous gases. The fan operates effectively at medium temperatures, typically not exceeding 50°C (with capabilities up to 80°C), and can handle dust and solid particles in the medium without surpassing 150 mg/m³. It is an ideal solution for industries including mining enterprises, chemical plants, smelters, workshops, warehouses, and electroplating facilities.

    Frequently Asked Questions
    Q What does the model number (e.g., 3.15A, 4A, 7.1A) represent in the parameter table?
    The model number typically refers to the impeller or fan diameter size (in inches or a scaled unit), which directly determines the airflow capacity, total pressure, and power requirements. Larger model numbers correspond to higher airflow and pressure output capabilities.
    Q Why does each model have two rows of parameters listed?
    Each model offers two configuration options with different power ratings (kW-P) and horsepower (HP) levels. This allows users to select the appropriate motor power based on their specific airflow (m³/h) and total pressure (Pa) requirements within the same fan model.
    Q What voltage and frequency are these fan models compatible with?
    All models in this parameter table are designed to operate at a standard voltage of 380V and a frequency of 50Hz, which is the common industrial power supply standard used in many countries including China, Europe, and other regions.
    Q How do I choose the right model based on my airflow and pressure requirements?
    First, determine your required airflow in m³/h and the total static pressure (Pa) needed for your ventilation system. Then match these values against the Traffic (m³/h) and Total Pressure (Pa) columns in the table. Select a model whose operating range covers your target values, and choose the appropriate power tier accordingly.
    Q What is the operating speed for all listed models, and can it be adjusted?
    All models listed in the table operate at a fixed speed of 2900 r/min (RPM). If variable speed operation is required for energy saving or flow control purposes, a compatible variable frequency drive (VFD/inverter) can be used — please consult with our technical team for compatibility guidance.
    Q What is the maximum power and airflow available across all models?
    The largest model in the table, 7.1A, offers the highest performance with a power rating of up to 55 kW (75 HP), a maximum airflow of up to 9,988 m³/h, and a total pressure of up to 11,717 Pa, making it suitable for large-scale industrial ventilation and air handling applications.
