All models within the DF series are designed to operate at a consistent high speed of 2900 r/min, ensuring reliable and efficient performance across different power specifications.
The entry-level 0.09-2 model operates on a standard 220V power supply. All other models in the DF series offer dual compatibility, supporting both 220V and 380V power systems at a 50Hz frequency.
The maximum traffic capacity is achieved by the 5.5-2 model, which delivers an impressive airflow ranging from 4500 to 7500 m³/h, making it ideal for heavy-duty industrial applications.
The noise levels are optimized for industrial standards, starting at a relatively quiet 72 dB(A) for lower horsepower models and reaching up to 85 dB(A) for the most powerful 7.5 HP model.
The DF series offers a wide range of power options to suit various needs, starting from 0.13 HP (0.09 kW) up to a robust 7.5 HP (5.5 kW).
