❓
Frequently Asked Questions
►
What is the difference between a steel impeller and an aluminum impeller?
Steel impellers offer higher strength and durability, making them suitable for environments with abrasive or corrosive particles. Aluminum impellers are lighter in weight, which reduces the overall load on the motor and can improve energy efficiency in standard ventilation applications.
►
What voltage and frequency are these fan models designed for?
All models listed in the parameter table operate at a standard voltage of 380V and a frequency of 50Hz, which is compatible with most industrial power supply systems worldwide.
►
What does the "Traffic (m³/h)" parameter indicate?
The "Traffic" value represents the airflow rate — the volume of air the fan can move per hour, measured in cubic meters per hour (m³/h). A higher value means greater air movement capacity, which is important for selecting the right fan for large industrial spaces.
►
How do I choose the right model based on total pressure (Pa)?
Total pressure (Pa) reflects the fan's ability to overcome resistance in a duct system. For applications with longer or more complex duct runs, choose a model with a higher total pressure rating. Match the required system resistance with the fan's pressure range for optimal performance.
►
Why do some models have two rows of parameters with different impeller materials?
Some fan models (such as 4A, 4.5A, 5A, etc.) are available with either a steel or aluminum impeller. Each impeller type results in slightly different airflow (m³/h) and total pressure (Pa) performance, allowing customers to select the configuration that best matches their specific application requirements.
►
What is the operating speed of these fan models?
All models in this series operate at a standard speed of 1450 r/min (revolutions per minute). This consistent speed across the range ensures stable and reliable performance, while the variation in model size and impeller type allows for a wide range of airflow and pressure outputs.
