Frequently Asked Questions
Q
What is the standard operating voltage and frequency for these fan models?
All models listed in the parameters table operate at a standard voltage of 380V and a frequency of 50Hz, making them compatible with standard industrial power supplies commonly used in manufacturing and HVAC applications.
Q
Why does each fan model have two power configuration options?
Each model offers two power configurations to provide flexibility for different airflow and pressure requirements. The lower power option handles moderate traffic and pressure needs, while the higher power option is suited for more demanding ventilation or industrial applications requiring greater airflow volume.
Q
What is the maximum airflow (traffic) achievable among all listed models?
The largest model, 7.1A, achieves the highest airflow of up to 9,988 m³/h at 55kW power, making it suitable for large-scale industrial ventilation systems that require high-volume air movement.
Q
How do I select the right model based on total pressure requirements?
Total pressure (Pa) increases as the model size increases. For example, model 3.15A provides a total pressure range of 2017–2262 Pa, while model 7.1A can reach up to 11,717 Pa. You should select a model whose total pressure range matches or exceeds the static resistance of your duct system.
Q
What does the "kW-P" notation in the Power column mean?
The "kW-P" notation refers to the motor power in kilowatts along with the number of poles (P). For example, 0.75-2 means 0.75 kW with a 2-pole motor, which corresponds to an approximate synchronous speed of 3000 r/min and an actual running speed of around 2900 r/min under load.
Q
Are these fan models suitable for export to countries with 60Hz power supply?
The standard specifications listed are designed for 50Hz power systems. For countries using 60Hz power supply (such as the USA, Canada, or parts of Latin America), custom configurations may be required. Please contact the manufacturer to inquire about 60Hz-compatible variants or frequency converter solutions.
