Frequently Asked Questions
Q
What does the model number (e.g., 3.15A, 4A, 6.3A) represent in the fan specifications?
The model number refers to the fan's impeller diameter in decimeters (dm). For example, model 3.15A has an impeller diameter of 315mm, while 6.3A indicates a 630mm diameter. The "A" designation typically denotes the blade angle or series type. Larger model numbers generally correspond to higher airflow capacity and greater power requirements.
Q
Why do some models offer two different speed options (960 r/min and 1450 r/min)?
Different motor pole configurations result in different synchronous speeds under a 50Hz power supply — 960 r/min corresponds to a 6-pole motor and 1450 r/min to a 4-pole motor. Higher speeds deliver greater airflow and total pressure but consume more power. Selecting the appropriate speed depends on your specific ventilation requirements, duct resistance, and energy efficiency goals.
Q
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 China and many other countries. If your facility operates on a different voltage or frequency (such as 60Hz or 220V), please consult with the manufacturer for compatible configurations.
Q
How do I select the right fan model based on airflow (Traffic) and total pressure requirements?
First, calculate the required airflow (m³/h) for your space based on room volume and desired air change rate. Then estimate the system resistance (total pressure in Pa) based on duct length, bends, and fittings. Match these values against the Traffic and Total Pressure ranges in the parameter table. Always choose a model whose performance range comfortably covers your operating point to ensure efficient and reliable operation.
Q
What does the Power (kW-P) specification mean, and how does it relate to Horsepower (HP)?
The Power (kW-P) value represents the rated motor power in kilowatts along with the number of poles (e.g., "5.5-4" means 5.5kW with a 4-pole motor). Horsepower (HP) is an alternative unit of power measurement commonly used in some markets. The conversion is approximately 1 HP ≈ 0.746 kW. Both values are provided to help engineers and buyers compare specifications across different regional standards.
Q
Can these fans be used in high-temperature or corrosive environments?
The standard models listed in the parameter table are designed for general industrial ventilation under normal temperature and non-corrosive conditions. For high-temperature exhaust, humid environments, or applications involving corrosive gases, special material variants (such as stainless steel or anti-corrosion coated versions) may be available. Please contact the manufacturer to discuss custom configurations suitable for your specific operating environment.
