Frequently Asked Questions
Q
What is the speed range available for these fan models?
The fans are available in two primary speed options: 2900 r/min (high speed) and 1450 r/min (standard speed). Smaller models such as Model 2 and Model 2.5 offer both speed options, while larger models (Model 5 and above) operate at 1450 r/min only.
Q
What voltage options are supported by these fans?
Models 2 through 7 support dual voltage of 220/380V, making them suitable for a wide range of electrical systems. Larger models — Model 8, 9, and 10 — operate exclusively at 380V, which is standard for industrial three-phase power supply.
Q
Which model provides the highest airflow (traffic) capacity?
Model 10 offers the highest airflow capacity at 48,000 m³/h, making it the best choice for large-scale industrial ventilation applications requiring maximum air volume throughput.
Q
What is the maximum total pressure achievable, and which model provides it?
Models 9 and 10 both achieve a maximum total pressure of 400 Pa. This makes them ideal for systems requiring high static pressure to overcome significant duct resistance or long-distance air delivery.
Q
Are all fan models compatible with 50 Hz electrical frequency?
Yes, all fan models listed in the parameter table 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.
Q
How do I choose the right fan model for my application?
Selecting the correct model depends on three key factors: required airflow (m³/h), system total pressure (Pa), and available power supply voltage. Match your ventilation system's airflow demand and resistance to the corresponding model in the parameter table. For high-volume, high-pressure requirements, consider Model 8–10. For smaller or dual-voltage applications, Models 2–4 are recommended.
