Frequently Asked Questions
Q
What is the difference between steel impeller and aluminum impeller models?
Steel impeller models are typically more durable and suited for handling corrosive or high-temperature airflows, while aluminum impeller models are lighter and offer slightly higher airflow capacity at the same power rating. The choice depends on your specific application environment and airflow requirements.
Q
What voltage and frequency are these fan models designed for?
All models listed in the parameter table operate at a standard voltage of 380V and a frequency of 50Hz, making them suitable for industrial electrical systems commonly used in Europe, Asia, and other regions with similar grid standards.
Q
What is the speed (RPM) of these centrifugal fan models?
All models in this series operate at a rated speed of 1450 r/min (RPM). This consistent speed across the range ensures stable performance and simplifies integration into existing ventilation and air-handling systems.
Q
How do I select the right model based on airflow (traffic) requirements?
Each model provides a range of airflow capacity (m³/h). You should first calculate the required airflow for your space or system, then select a model whose traffic range covers your requirement. For example, if you need approximately 10,000 m³/h, models such as 5A, 5.6A, or 6A would be appropriate candidates to evaluate further based on total pressure needs.
Q
What does the total pressure (Pa) range indicate in the parameter table?
The total pressure range (in Pascals) represents the static and dynamic pressure the fan can generate across its operating airflow range. A higher total pressure value means the fan can overcome greater resistance in ductwork and filtration systems. When selecting a model, ensure the fan's total pressure at your required airflow point meets or exceeds your system's resistance.
Q
Which model is suitable for large-scale industrial ventilation with high airflow demands?
For large-scale industrial applications requiring very high airflow, the 8A model is the most powerful option in this series, offering a traffic range of 18,850–32,300 m³/h, a total pressure of 2,000–2,670 Pa, and a power rating of 15 kW (20.5 HP). It features an aluminum impeller and is well-suited for demanding industrial ventilation scenarios.
