Frequently Asked Questions
Q
What does the model number (e.g., 2.5A, 4A) indicate in the parameters table?
A
The model number refers to the fan size designation. The numeric value generally corresponds to the impeller diameter or series classification, while the letter "A" denotes a specific design variant. Different models are suited to different airflow and pressure requirements.
Q
Why do some models (such as 3A, 3.5A, 4A, and 4.5A) have multiple speed options listed?
A
These models are available with different motor pole configurations — typically 4-pole (1450 r/min) and 6-pole (960 r/min) — allowing users to select a speed that best matches their ventilation system's airflow and pressure demands.
Q
What voltage options are supported, and are these fans suitable for international use?
A
Smaller models (2.5A to 3.5A) support both 220V and 380V, making them flexible for various electrical systems. Larger models (4A and above) operate on 380V only. All units run at 50 Hz, which is standard in most regions outside North America.
Q
How do I select the right model based on traffic (airflow) and total pressure requirements?
A
First, calculate the required airflow (m³/h) and static pressure (Pa) for your application. Then match these values to the Traffic and Total Pressure ranges in the table. Select a model whose range comfortably covers your operating point for optimal efficiency.
Q
What is the relationship between power (kW-P) and horsepower (HP) in this table?
A
The power values listed in kW-P represent the motor's rated power in kilowatts along with the pole number (e.g., "5.5-4" means 5.5 kW, 4-pole motor). The horsepower (HP) column provides the equivalent imperial power rating for reference, where approximately 0.75 kW equals 1 HP.
Q
Which model offers the highest airflow capacity, and what are its specifications?
A
The Model 6A offers the highest airflow capacity, with a traffic range of 13,000–20,000 m³/h and a total pressure of 1,200–1,000 Pa. It operates at 960 r/min with a 7.5 kW (6-pole) motor at 380V/50Hz, rated at 10 HP — making it ideal for large-scale industrial ventilation applications.
