Frequently Asked Questions
What does the model number (e.g., 2.5A, 4A, 6A) represent?
The model number indicates the fan size classification. A larger model number generally corresponds to a larger fan wheel diameter, higher airflow capacity (m³/h), and greater total pressure output, making it suitable for more demanding ventilation applications.
What is the difference between 1450 r/min and 960 r/min motor speeds?
1450 r/min motors are typically 4-pole motors offering higher speed and greater airflow, while 960 r/min motors are 6-pole motors that run at lower speed, resulting in quieter operation and reduced energy consumption — ideal for applications where noise control is a priority.
Can these fans operate on both 220V and 380V power supplies?
Smaller models (2.5A to 3.5A) support dual voltage of 220V/380V, offering greater flexibility for different electrical installations. Larger models (4A and above) are designed exclusively for 380V power supply, which is standard for industrial environments.
How do I select the right model based on traffic (airflow) requirements?
First, calculate the required airflow volume (m³/h) for your space based on room volume and air change rate. Then match it to the Traffic column in the parameters table. For example, if you need approximately 13,000–20,000 m³/h, the 6A model at 960 r/min would be appropriate.
What does "Total Pressure (Pa)" mean and why is it important?
Total pressure (measured in Pascals) represents the fan's ability to overcome resistance in the duct system. Higher total pressure means the fan can push air effectively through longer or more complex duct networks. It is critical to match the fan's total pressure to the system's resistance curve for optimal performance.
Are all models compatible with a 50 Hz power supply frequency?
Yes, all models listed in the parameters table are designed to operate at a standard frequency of 50 Hz, which is the common power supply frequency used across most countries in Asia, Europe, Africa, and Australia.
