Frequently Asked Questions
Q
What fan models are available and what do the size designations mean?
The fans are available in five standard models: 2" (8"), 2.5" (10"), 3" (12"), 3.5" (14"), 4" (16"), and 5" (20"). The number indicates the fan blade diameter in inches, allowing users to select the appropriate size based on airflow and installation requirements.
Q
What speed options are available and how do they affect performance?
Each model supports multiple speed settings. For 50 Hz operation, speeds of 2900 r/min (2-pole) and 1450 r/min (4-pole) are available. For 60 Hz operation, speeds increase to approximately 3200 r/min and 1630 r/min respectively. Higher speeds deliver greater airflow (m³/h) and total pressure (Pa), while lower speeds offer quieter and more energy-efficient operation.
Q
What voltage and frequency options are supported?
All models support dual voltage operation at 220V and 380V. Both 50 Hz (standard in most of Asia, Europe, and Australia) and 60 Hz (standard in North America and parts of Latin America) frequencies are available, making these fans suitable for global applications.
Q
What is the difference between the standard fan parameters and the booster net cover parameters?
The booster net cover series (available in 3", 4", and 5" models) is designed to enhance airflow delivery with a net cover attachment. Compared to the standard fan of the same model, the booster net cover version typically achieves slightly higher traffic (m³/h) and total pressure (Pa) values, making it ideal for applications requiring boosted ventilation performance.
Q
How do I select the right power (kW) and horsepower (HP) rating for my application?
Power ratings vary by model and pole configuration. For example, the 2" (8") model ranges from 0.09 kW (4-pole) to 0.12 kW (2-pole), while the 5" (20") model goes up to 2.2 kW (2-pole). Select a higher power rating when you need greater airflow or pressure. Horsepower (HP) ratings are provided for reference in markets where HP is the standard unit.
Q
Which model is recommended for large-scale ventilation needs?
For large-scale ventilation requirements, the 5" (20") model is the most powerful option, delivering up to 18,000 m³/h traffic at 3200 r/min with a power rating of 2.2 kW (2-pole). The booster net cover version of the 5" model further increases airflow to 15,750 m³/h at 2900 r/min with a total pressure of 450 Pa, making it highly suitable for industrial or commercial ventilation systems.
