Frequently Asked Questions
Q
What does the model number (e.g., 2.8A, 3A·S, 5A) represent?
The model number indicates the fan size and series classification. The numeric value generally refers to the impeller diameter or capacity rating, while suffixes like S (Small), M (Medium), and L (Large) denote the physical size variant within the same series.
Q
Why do some models offer two different speed and power configurations?
Models such as 2.8A, 3.5A, and 5A are available in dual configurations to provide flexibility for different application requirements — allowing users to choose between lower power consumption or higher airflow output depending on their ventilation needs.
Q
What voltage options are available for these fan models?
Smaller models (2.8A to 3.5A) support dual voltage of 220V/380V, making them compatible with both single-phase and three-phase power supplies. Larger models (4A and above) operate on 380V only, which is standard for industrial three-phase power systems.
Q
What is the significance of the total pressure (Pa) range listed in the parameters?
The total pressure range (in Pascals) indicates the static and dynamic pressure the fan can generate across its operating airflow range. A higher pressure value means the fan can overcome greater resistance in ductwork or filtration systems, making it suitable for more demanding ventilation setups.
Q
How do I select the right model based on traffic (airflow) requirements?
Choose a model whose traffic (m³/h) range covers your required airflow volume. For example, if your application requires approximately 10,000–15,000 m³/h, the 5A model at 960 r/min with 5.5 kW would be the appropriate selection. Always consider both airflow and total pressure to ensure optimal performance.
Q
Are all models designed for 50 Hz power supply systems?
Yes, all models listed in the parameter table are designed to operate at a standard frequency of 50 Hz, which is the common power supply frequency used in most countries across Asia, Europe, Africa, and Australia. For 60 Hz markets (such as North America), please consult the manufacturer for compatible specifications.
