Frequently Asked Questions
Q
What is the standard operating speed of the DF series fans?
A
All models in the DF series operate at a consistent high speed of 2900 r/min, ensuring highly efficient performance across all sizes.
Q
What are the voltage requirements for these models?
A
The base model operates on 220V, while the majority of the upgraded DF models are compatible with 220/380V dual voltage at a 50Hz frequency.
Q
How much airflow (traffic) can the largest DF model handle?
A
The highest capacity model (7.5 HP) can generate a massive traffic volume ranging from 4500 to 7500 m³/h, making it ideal for large-scale industrial applications.
Q
What is the power range available in the DF series?
A
The power output ranges from 0.09 kW (0.13 HP) for the smallest unit up to 5.5 kW (7.5 HP) for the most robust model.
Q
Are these fans noisy during operation?
A
The noise levels are optimized for industrial environments. They start at 72 dB(A) for lower-power models and reach a maximum of 85 dB(A) for the heavy-duty 7.5 HP version.
Q
What is the maximum total pressure provided by these fans?
A
The total pressure varies depending on the specific model, starting at 330 Pa and reaching up to a maximum of 1800 Pa for the higher-capacity units.
