Frequently Asked Questions
Q
What does the model number represent in the fan parameter table?
The model number (e.g., 2, 2.5, 3 … 10) refers to the fan size designation, which typically corresponds to the impeller diameter in decimeters. A higher model number generally indicates a larger fan capable of handling greater airflow volumes and higher power ratings.
Q
What is the difference between 2900 r/min and 1450 r/min speed options?
The 2900 r/min speed option delivers higher airflow (traffic) and total pressure, making it suitable for applications requiring stronger ventilation performance. The 1450 r/min option operates at lower speed, consuming less power and producing less noise, which is ideal for environments where quieter operation is preferred.
Q
Which models support both 220V and 380V voltage?
Models 2 through 7 support dual voltage operation at 220V/380V, providing flexibility for different electrical installations. Models 8, 9, and 10 are designed exclusively for 380V supply, which is standard for higher-power industrial fan applications.
Q
How do I select the right fan model based on traffic (airflow) requirements?
First, calculate the required airflow volume (m³/h) for your space or application. Then match that value to the "Traffic" column in the parameter table. For example, if you need approximately 18,700 m³/h, Model 6 at 1450 r/min would be the appropriate choice. Always consider total pressure (Pa) requirements alongside airflow when making your selection.
Q
All models operate at 50 Hz — does this mean they are only suitable for specific regions?
Yes, all models listed in the parameter table are rated at 50 Hz, which is the standard power frequency used in most countries across Europe, Asia, Africa, and Australia. If your facility operates on a 60 Hz power supply (common in North America and parts of Latin America), please consult with our technical team for compatible configurations.
Q
What is the relationship between horsepower (HP) and power (kW) in the specifications?
The power column (kW-P) indicates the motor's rated power in kilowatts along with the number of poles (e.g., "0.75-4" means 0.75 kW with 4 poles). The horsepower (HP) column provides the equivalent power rating in HP for reference. Approximately 1 HP equals 0.746 kW, so these values are consistent across the table. Both figures help users select compatible motors and electrical components.
