Frequently Asked Questions
Q1
What does the "Power (kW-P)" column represent in the DF fan parameters?
The "Power (kW-P)" column indicates the rated motor power of the DF series fan in kilowatts. The range shown (e.g., 0.09-2) reflects the available power configurations within that model variant, allowing users to select the appropriate motor size for their specific airflow and pressure requirements.
Q2
What voltage options are available for the DF series fans?
Most DF series fan models support dual voltage operation at 220V and 380V, making them compatible with a wide range of electrical supply systems. The entry-level model (0.09-2 kW) operates on 220V only, while all higher-power models support both 220V and 380V at 50 Hz.
Q3
What is the maximum airflow (traffic) achievable with the DF fan series?
The highest airflow capacity in the DF series reaches up to 7,500 m³/h, available in the 5.5-2 kW model. This makes it suitable for large-scale industrial ventilation applications requiring high-volume air movement.
Q4
How does noise level (dB(A)) vary across different DF fan models?
Noise levels increase gradually as power and airflow capacity increase. Lower-power models (0.09–0.12 kW) operate at 72 dB(A), while the largest model (5.5-2 kW) reaches up to 85 dB(A). For noise-sensitive environments, it is recommended to select lower-power models or implement appropriate acoustic insulation.
Q5
What is the operating speed of the DF series fans?
All DF series fan models in this specification table operate at a consistent speed of 2,900 r/min (revolutions per minute). This standardized speed ensures stable performance and simplifies system design for engineers and installers.
Q6
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 static pressure (Pa), available power supply voltage, and acceptable noise level. Match your system's demand against the parameter table — for example, if you need approximately 850 m³/h at 1,020 Pa, the 0.55-2 kW model would be the appropriate choice.
