Frequently Asked Questions
Q
What does the model number (e.g., 3.5, 4, 5) represent in the fan specifications?
The model number refers to the fan blade diameter in inches. For example, model 3.5 (14") indicates a fan with a 14-inch (approximately 3.5 dm) blade diameter, while model 9 (36") refers to a 36-inch blade. The larger the model number, the greater the airflow capacity.
Q
What is the difference between 50 Hz and 60 Hz operation for these fans?
50 Hz is the standard power frequency used in most countries including China, Europe, and Asia, while 60 Hz is used in North America and some other regions. Running a fan at 60 Hz (1630 r/min) results in higher speed, greater airflow (m³/h), and increased total pressure (Pa) compared to 50 Hz (1450 r/min) operation.
Q
What is the purpose of the Booster Net Cover, and how do its parameters differ from the standard fan?
The Booster Net Cover is an accessory designed to enhance airflow performance by increasing total pressure output. Compared to the standard fan configuration, models fitted with a Booster Net Cover (e.g., 4"/16" at 2900 r/min) achieve a higher total pressure of 600 Pa versus 476 Pa, making them suitable for applications requiring stronger air pressure.
Q
What voltage options are available for these fan models?
Most fan models support dual voltage operation at 220V/380V, making them compatible with both single-phase and three-phase power supplies. Larger models such as 8 (32") and 9 (36") operate at 380V only, which is standard for higher-power industrial applications.
Q
How do I select the right fan model based on airflow (Traffic) requirements?
To select the right model, first determine the required airflow volume in m³/h for your application. Then match this value to the Traffic column in the parameter table. For example, if you need approximately 18,000–22,000 m³/h, models 6 (24") or 6.3 (25.2") at 1450 r/min would be suitable choices.
Q
What is the significance of the Power (kW-P) range listed in the specifications?
The Power (kW-P) value indicates the motor power rating combined with the number of poles (P). For instance, "0.75-4" means a 0.75 kW motor with 4 poles. The number of poles affects the motor's synchronous speed — a 4-pole motor runs at approximately 1450 r/min at 50 Hz, while a 2-pole motor runs at approximately 2900 r/min. This directly impacts the fan's speed, airflow, and energy consumption.
