The 'industrial mobile fan product coefficient' is not a fixed standard value like 'power' or 'air volume'. It is usually not a number directly listed on the specification sheet.
The answer to this question depends on what you specifically mean by 'coefficient'. In the field of industrial fans, several key performance parameters collectively determine the performance of the fan, and we can understand these parameters as its "coefficients".
Here are several important "coefficients" or performance parameters that you can refer to according to your needs:
1. Airflow core coefficient
This is an important indicator, which refers to the volume of air delivered by the fan per unit time.
Unit: cubic meters per minute (m ³/min) or cubic meters per hour (m ³/h).
Meaning: It directly determines the ventilation and cooling capacity of the fan. The air volume of industrial fans is usually very large, ranging from several thousand to tens of thousands of cubic meters per hour.
What is the air volume (or exhaust volume) of this fan
2. Wind pressure - coefficient to overcome resistance
Refers to the total pressure generated by a fan, used to overcome the resistance of ventilation systems such as pipes and filters.
Unit: Pascal (Pa).
Meaning: If the fan needs to be connected to a long pipeline or has a filtering device, it requires a higher air pressure. For a simple mobile circulating fan, this parameter is relatively secondary.
What is the static/total pressure of this fan
3. Power energy consumption coefficient
Refers to the amount of electricity consumed by a fan during operation.
Unit: Watt (W) or Kilowatt (kW).
Meaning: Related to operating costs. Please note that high power does not necessarily mean high air volume, and efficiency is also crucial.
What is the input power of this fan
4. Efficiency - Comprehensive Performance Coefficient
The efficiency of converting electrical energy into air kinetic energy by a fan is a key indicator for measuring the performance of a fan.
Calculation formula: Efficiency=(output air power/input electric power) x percentage
Meaning: The higher the efficiency, the more energy can be saved by providing greater air volume while consuming the same amount of electricity.
You need to ask, 'What is the efficiency of this fan?' (but this parameter is not often directly provided by the manufacturer)
5. Noise Environmental Impact Coefficient
The sound level produced by the fan during operation.
Unit: Decibel (dB).
Meaning: It is very important in environments that require quietness or long-term work.
What is the noise level of this fan
How to obtain the "coefficient" you need?
Check the product nameplate: The fan body usually has a nameplate with basic information such as voltage (V), frequency (Hz), power (W or kW), speed (RPM), etc.
Refer to the product manual or technical manual: This is a reliable way to obtain detailed performance parameters such as air volume, air pressure, noise, etc. Legitimate industrial fan manufacturers will provide detailed technical information.
Contact suppliers or manufacturers: directly request the performance curve graph of the product from them. This chart will clearly show the relationship between wind pressure, power, and efficiency under different air volumes, making it a better tool for selecting fans that are suitable for your operating conditions.
For example:
Assuming you see an industrial mobile fan, its key "coefficient" may be as follows:
Model: GF-30
Airflow: 4500 m ³/h
Power: 550 W
High wind pressure: 120 Pa
Noise: 65 dB
Fan blade diameter: 500 mm
Summary:
Please do not search for a single "product coefficient", but focus on the two core parameters of air volume and power based on your specific application scenario (such as whether it is used for overall ventilation in the workshop or for strong cooling in specific areas? Is there a pipeline system?), and refer to the noise level.
If you can provide the specific brand and model of the fan, or your specific usage scenario, I can help you analyze which parameters are important to you.
