Frequently Asked Questions
What do the model numbers (e.g., 4A, 5A, 6.3A) represent?
The model numbers refer to the fan wheel diameter size category. A larger number generally indicates a larger fan capable of handling higher airflow volumes and total pressures, making it suitable for bigger ventilation systems or industrial applications.
Why do some models have multiple power (kW-P) options listed?
Some models (such as 4.5A, 5A, and 6.3A) are available with different motor power configurations to accommodate varying traffic (airflow) and total pressure requirements. This flexibility allows users to select the most energy-efficient option for their specific application.
What is the standard operating voltage and frequency for these fans?
All models listed in the parameter table operate at a standard voltage of 380V and a frequency of 50Hz, which is the common industrial power supply standard used in many countries including China and most of Europe.
What does "Total Pressure (Pa)" indicate in the parameter table?
Total pressure (measured in Pascals) represents the fan's ability to overcome resistance in the ventilation system. A higher total pressure value means the fan can push air through longer duct runs or systems with more resistance. The range shown (e.g., 581–402 Pa) corresponds to the airflow range from minimum to maximum traffic.
How do I select the right model for my ventilation project?
To select the correct model, first determine your required airflow (m³/h) and the total static pressure of your duct system (Pa). Then match these values against the Traffic and Total Pressure ranges in the parameter table. Choose the model and power option whose ranges comfortably cover your requirements for optimal efficiency and reliability.
What is the operating speed of these fans, and can it be adjusted?
All models in this series operate at a rated speed of 1450 r/min (RPM), which is typical for 4-pole motors running on a 50Hz power supply. If variable speed operation is required, a compatible variable frequency drive (VFD) can be used — please consult the manufacturer for compatibility and recommendations.
