Frequently Asked Questions
Q1
What is the difference between 4-pole and 6-pole fan models in this series?
The number following the dash in the Power (kW-P) column indicates the number of motor poles. 4-pole motors typically run at 1450 r/min and deliver higher total pressure, making them suitable for applications requiring strong airflow resistance. 6-pole motors run at 960 r/min, offering quieter operation and lower energy consumption, ideal for applications where noise reduction is a priority.
Q2
Which models support both 220V and 380V voltage input?
Models 2.8A, 3A, 3.2A (1450 r/min variant), and 3.5A (1450 r/min variants) support dual voltage input of 220V/380V. Larger models such as 4A, 4.5A, 5A, and 6A are designed exclusively for 380V power supply, which is standard for industrial environments.
Q3
How do I select the right model based on required airflow (Traffic)?
Match your required airflow volume (m³/h) to the Traffic range listed in the parameters table. For example, if your system requires approximately 10,000–15,000 m³/h, models 4.5A or 5A would be appropriate candidates. Always consider total pressure requirements alongside airflow to ensure optimal system performance.
Q4
What does the total pressure range (Pa) indicate in the specifications?
The total pressure range represents the static and dynamic pressure the fan can generate across its operating airflow range. A higher Pa value indicates the fan can overcome greater resistance in ductwork or filtration systems. When selecting a model, ensure the fan's total pressure at your target airflow point meets or exceeds the system resistance of your installation.
Q5
All models operate at 50 Hz — are 60 Hz versions available?
The parameter table lists all standard models at 50 Hz frequency, which is the standard for most countries in Asia, Europe, and Africa. For markets using 60 Hz power supply (such as North America or parts of South America), please contact the manufacturer directly to inquire about customized 60 Hz configurations or frequency converter solutions.
Q6
Why does the same model number (e.g., 3A or 4A) have multiple rows of specifications?
Some model numbers (such as 3A, 3.2A, 3.5A, 4A, 4.5A, and 5A) offer multiple motor and speed configurations under the same fan housing size. This allows users to select the appropriate power output, speed, and pole configuration to best suit their application requirements — whether prioritizing higher pressure, greater airflow, energy efficiency, or quieter operation.
