Frequently Asked Questions
1
What does the model number (e.g., 4A, 5.6A) represent in the parameter table?
The model number refers to the fan or blower series designation, which typically indicates the impeller diameter or blade size category. Different model numbers correspond to different airflow capacities, pressure ranges, and power requirements, allowing users to select the right unit for their specific ventilation application.
2
Why do some models (e.g., 4.5A, 5A, 5.6A, 6.3A) have two rows of parameters?
Some models offer multiple power and airflow configurations under the same motor speed. This means a single model series can be supplied with different motor ratings (e.g., 1.5 kW vs. 2.2 kW), giving customers flexibility to choose the version that best matches their traffic volume and total pressure requirements.
3
What is the standard operating voltage and frequency for these units?
All models listed in the parameter table operate at a standard voltage of 380V and a frequency of 50Hz. This is consistent with standard three-phase industrial power supply specifications commonly used in commercial and industrial ventilation systems.
4
How do I choose the right model based on traffic (airflow) and total pressure requirements?
To select the correct model, first calculate the required airflow (m³/h) and the total static pressure (Pa) needed for your duct system. Then match these values against the traffic and total pressure ranges listed in the table. Choose a model whose range comfortably covers your calculated requirements, and verify the power rating (kW) is compatible with your electrical installation.
5
What is the relationship between horsepower (HP) and power (kW) in these specifications?
Horsepower (HP) and kilowatts (kW) are both units of motor power. In these specifications, they refer to the same motor output expressed in different unit systems. Approximately 1 HP equals 0.746 kW. For example, a 5.5 kW motor corresponds to approximately 7.5 HP. Both values are provided to accommodate different regional standards and purchasing preferences.
6
Is it possible to customize the voltage or frequency for export markets?
While the standard specification is 380V / 50Hz, many manufacturers offer customized motor configurations for export markets that require different voltages (e.g., 415V, 460V) or frequencies (e.g., 60Hz). Please contact the supplier directly to discuss OEM or custom electrical specifications for your specific regional requirements.
