Frequently Asked Questions
Q What is the speed range available for these fan models?
The fan models operate at various speeds including 2900 r/min, 1450 r/min, and 960 r/min, depending on the model and pole configuration. Higher-speed models (2900 r/min) are typically 2-pole motors, while lower-speed models (1450 r/min and 960 r/min) use 4-pole or 6-pole motors.
Q What voltage options are supported by these fans?
Most models support dual voltage operation at 220V/380V, making them suitable for a wide range of electrical installations. Larger models such as 4A, 4.5A, 5A, 5.6A, 6A, 6.3A, and 7.1A operate at 380V only, which is standard for higher-power industrial applications.
Q Which model provides the highest airflow (traffic) capacity?
The model 5.6A operating at 2900 r/min delivers the highest airflow, ranging from 10,122 to 25,736 m³/h. This makes it ideal for large-scale industrial ventilation systems requiring high air volume.
Q What is the maximum total pressure achievable among all listed models?
The model 5.6A at 2900 r/min achieves the highest total pressure, ranging from 2,330 Pa to 4,152 Pa. High total pressure is critical for systems with long duct runs or significant resistance in the air distribution network.
Q Are these fans available in both single-speed and dual-speed configurations?
Yes. Several models — including 3.2A, 3.6A, 4A, 4.5A, 5A, 5.6A, and 7.1A — are available in dual-speed configurations, offering both 2900 r/min and 1450 r/min (or 960 r/min for 7.1A) options. This provides greater flexibility in matching airflow and pressure requirements to specific applications.
Q What frequency do these fans operate at, and are they compatible with standard power supplies?
All models in this series operate at a standard frequency of 50 Hz, which is the most widely used power supply frequency in regions including Europe, Asia, Africa, and Australia. This ensures broad compatibility with standard industrial and commercial electrical infrastructure worldwide.
