Frequently Asked Questions
Q1
What does the model number (e.g., 4A, 5A, 6.3A) represent in the fan parameters table?
The model number indicates the fan's impeller diameter size. A larger number corresponds to a physically larger fan wheel, which typically delivers higher airflow (m³/h) and total pressure (Pa) output, making it suitable for larger ventilation systems.
Q2
Why do some models (e.g., 4.5A, 5A, 5.6A) have multiple rows of specifications?
Multiple rows for a single model indicate that the fan is available with different motor power options (kW-P) and corresponding horsepower (HP) ratings. This allows users to select the appropriate power level based on their specific airflow and pressure requirements.
Q3
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, which is the common industrial power supply standard used in many regions including Europe, Asia, and the Middle East.
Q4
How do I select the right fan model based on traffic (airflow) and total pressure requirements?
First, calculate the required airflow (m³/h) and total pressure (Pa) for your ventilation system. Then match these values against the ranges listed in the table. For example, if you need approximately 10,000–18,000 m³/h with a pressure around 780–1440 Pa, the 6A model would be a suitable choice.
Q5
What is the significance of the speed (r/min) value listed for each model?
The speed value (1450 r/min for all listed models) refers to the rotational speed of the fan motor shaft. All models operate at 1450 RPM, which is the standard synchronous speed for a 4-pole motor running on a 50Hz power supply, ensuring consistent and reliable performance across the range.
Q6
Can these fan models be used in high-temperature or special industrial environments?
The suitability of a fan model for high-temperature or special industrial environments depends on the specific construction materials and motor insulation class. Please consult the product datasheet or contact our technical team to confirm compatibility with your specific application conditions, such as elevated temperatures, corrosive gases, or explosive atmospheres.
