Frequently Asked Questions
Q1
What is the difference between 2900 r/min and 1450 r/min speed options?
The 2900 r/min models operate at higher speeds, delivering greater airflow (traffic) and higher total pressure, making them suitable for demanding ventilation applications. The 1450 r/min models run at lower speeds, consuming less power and producing lower noise levels, which is ideal for environments where quiet operation is a priority.
Q2
Which voltage options are available for these fan models?
Smaller models (Model 2 through Model 7) support dual voltage of 220/380V, offering flexibility for different power supply environments. Larger models (Model 8, 9, and 10) operate exclusively at 380V, which is standard for higher-power industrial applications.
Q3
How do I select the correct model based on my required airflow (traffic)?
Identify the required airflow volume (m³/h) for your application. Then refer to the Traffic column in the parameter table and choose the model whose traffic value meets or exceeds your requirement. For example, if you need approximately 18,000 m³/h, Model 6 at 1450 r/min with 18,700 m³/h would be an appropriate choice.
Q4
What does the "kW-P" notation in the Power column mean?
The "kW-P" notation indicates the motor power rating in kilowatts along with the number of poles (P). For example, "0.75-4" means 0.75 kW motor power with a 4-pole motor configuration. The number of poles directly affects the motor's synchronous speed and efficiency characteristics.
Q5
Are all models compatible with a 50 Hz power supply?
Yes, all models listed in the parameter table are designed to operate at a frequency of 50 Hz, which is the standard power supply frequency used across most countries in Asia, Europe, Africa, and Australia. If your local power supply operates at 60 Hz, please consult the manufacturer for compatibility.
Q6
What is the significance of total pressure (Pa) in selecting a fan?
Total pressure (measured in Pascals) indicates the fan's ability to overcome resistance within a duct or ventilation system. A higher total pressure value means the fan can push air through longer or more complex duct systems with greater resistance. When designing a ventilation system, ensure the selected fan's total pressure meets or exceeds the calculated system resistance to achieve the desired airflow performance.
