Frequently Asked Questions
Q
What voltage options are available for the fan models listed?
Most smaller models (2.8A through 3.5A) support dual voltage at 220/380V, while larger models (4A, 4.5A, and 5A) operate at 380V only. Please verify your local power supply before selecting a model.
Q
What is the operating frequency for all models in this series?
All models in this series operate at a standard frequency of 50 Hz, which is compatible with most power grids in Europe, Asia, and other regions outside North America.
Q
Which model provides the highest airflow (traffic) capacity?
The 5A model at 1450 r/min offers the highest airflow capacity, ranging from 12,950 to 18,320 m³/h, making it ideal for large-scale ventilation and industrial air-handling applications.
Q
Why do some models (2.8A, 3.5A, 5A) have two rows of specifications?
These models are available in two different power and performance configurations under the same model name. This gives users flexibility to select the configuration that best matches their airflow, pressure, and horsepower requirements.
Q
How do I choose between the 3A·S, 3A·M, and 3A·L variants?
The S (Small), M (Medium), and L (Large) variants of the 3A series differ in airflow and total pressure output. Choose 3A·S for lower airflow needs (2,750–4,050 m³/h), 3A·M for medium requirements (3,270–4,950 m³/h), and 3A·L for higher capacity needs (3,950–5,250 m³/h).
Q
What does the total pressure range (Pa) indicate for these fan models?
The total pressure range (in Pascals) indicates the static and dynamic pressure the fan can generate across its operating airflow range. Higher Pa values mean the fan can overcome greater resistance in ductwork or filtration systems, which is important for complex ventilation installations.
