Frequently Asked Questions
Q
What is the operating voltage for all fan models listed in the parameters table?
All fan models listed in the parameters table operate at a standard voltage of 380V and a frequency of 50Hz, making them suitable for standard industrial power supplies.
Q
What is the difference between steel impeller and aluminum impeller options?
Steel impellers offer higher strength and durability, making them ideal for handling abrasive or high-temperature airflows. Aluminum impellers are lighter, corrosion-resistant, and better suited for general ventilation applications where weight reduction is beneficial. Many models are available in both options to suit different application requirements.
Q
Which model provides the highest airflow (traffic) capacity?
The 8A model offers the highest airflow capacity, with a traffic range of 18,850–32,300 m³/h and a power rating of 15 kW (20.5 HP), making it the most powerful option in the lineup for large-scale industrial ventilation needs.
Q
What does the speed rating of 1450 r/min mean, and is it consistent across all models?
The speed rating of 1450 r/min refers to the rotational speed of the fan impeller per minute. Yes, all models in this series operate at a consistent speed of 1450 r/min, which corresponds to a standard 4-pole motor running at 50Hz — ensuring stable and predictable performance across the entire product range.
Q
How do I select the right model based on my ventilation requirements?
To select the right model, first determine your required airflow volume (m³/h) and total pressure (Pa) based on your duct system and space size. Then match these values to the corresponding model in the parameters table. Also consider whether a steel or aluminum impeller better suits your operating environment (e.g., temperature, corrosion exposure, or air composition).
Q
Can these fans be used in both industrial and commercial ventilation systems?
Yes. The fan series covers a wide range of power outputs from 0.55 kW to 15 kW and airflow capacities from approximately 2,110 m³/h up to 32,300 m³/h, making them suitable for both commercial HVAC systems and large-scale industrial ventilation, exhaust, and air circulation applications.
