    Frequently Asked Questions

    Q What is the operating speed of the DF series fans listed in the parameters?
    All DF series fan models listed in the parameters table operate at a standard speed of 2900 r/min, making them high-speed centrifugal fans suitable for a wide range of industrial ventilation applications.
    Q What voltage options are available for the DF series fans?
    Most DF series models support dual voltage of 220V / 380V at 50 Hz. The smallest model (0.09-2 kW) operates on 220V only. This flexibility allows the fans to be used in both single-phase and three-phase power supply environments.
    Q What is the maximum airflow (traffic) that the DF series can achieve?
    The highest-capacity model in this range (5.5-2 kW / 7.5 HP) can deliver an airflow of up to 4,500–7,500 m³/h, making it ideal for large-scale industrial ventilation, dust extraction, and air circulation systems.
    Q How does noise level vary across different DF fan models?
    Noise levels range from 72 dB(A) for smaller models (0.09–0.12 kW) up to 85 dB(A) for the largest model (5.5-2 kW). As power and airflow capacity increase, the noise level increases accordingly. Appropriate hearing protection is recommended when operating higher-power units.
    Q What is the total pressure range available in the DF fan series?
    The total pressure (static pressure) of DF series fans ranges from 330 Pa (for the 0.09-2 kW model) up to 1,800 Pa (for the 5.5-2 kW model). Higher total pressure models are suitable for systems with greater duct resistance or longer duct runs.
    Q How do I select the right DF fan model for my application?
    To select the correct DF fan model, consider your required airflow (m³/h), total system pressure (Pa), available power supply voltage, and acceptable noise level. Match these requirements against the parameters table above. For complex installations or custom requirements, please contact our technical team for professional guidance.
