    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, which ensures consistent and reliable airflow performance across the entire product range.
    Q What voltage options are available for the DF series fans?
    Most DF series models support dual voltage of 220V / 380V, making them compatible with a wide range of industrial and commercial electrical systems. The entry-level model (0.09-2 kW) operates on 220V only.
    Q What is the airflow range (traffic) covered by the DF fan series?
    The DF fan series covers a wide airflow range, from 240 m³/h for the smallest model up to 4,500–7,500 m³/h for the largest 5.5 kW model, making it suitable for applications from small ventilation needs to large-scale industrial air movement.
    Q How does noise level vary across different DF fan models?
    Noise levels increase gradually with fan power. Smaller models (0.09–0.12 kW) produce as low as 72 dB(A), while larger models such as the 5.5 kW unit reach up to 85 dB(A). Appropriate sound insulation measures are recommended for high-power installations.
    Q What is the total pressure range provided by the DF fan series?
    Total pressure ranges from 330 Pa for the smallest model to 1,580–1,800 Pa for the largest 5.5 kW unit. Higher total pressure models are ideal for systems with longer duct runs or higher resistance requirements.
    Q What frequency do the DF series fans operate at, and are they suitable for international use?
    All DF series fans operate at 50 Hz, which is the standard frequency used across Europe, Asia, Africa, and many other regions worldwide. For markets using 60 Hz power (such as North America), please consult with our technical team regarding compatibility and available configurations.
