20ft Industrial Ceiling Fan Performance Index
Large fans have significant energy-saving advantages in industrial building air circulation applications. Generally, the larger the fan diameter, the greater the amount of air generated by unit energy consumption.
The deceleration fan has unstoppably developed into a permanent magnet direct drive fan. The energy saving effect of the direct drive fan is significantly improved compared with the traditional deceleration fan. At the same time, the operating noise is significantly reduced, and the life and reliability are significantly improved.
Since the reduction gearbox is eliminated, pollution due to lubricant leakage does not occur, and maintenance-free for the entire life is achieved.
A standard factory building of 10,000 square meters only needs to install 5-10 large-scale 7.3 meter fans, which is more than 70% energy-efficient than traditional distributed small fans. The average annual electricity cost savings is more than 1500USD.
Our industrial fan is a benchmark for domestic lightweight design, and at the same time, it is also a benchmark for the efficiency of direct-drive fans.
The fan has an efficiency of 84% within the speed range, especially under 70% of the highest speed load the motor efficiency can be achieved 90%;
Optimized Design of the Fan Drive and Direct Drive Motor:
1. The dedicated fan drive uses a fanless cooling design, even the fan cooling is not used, the temperature rise of our drive system is controlled within 20 degrees;
2. By optimizing the structural design, no traditional fan distribution box is needed to save investment and installation space for customers;
3. Designed and optimized software to achieve better electromagnetic noise control goals;
4. Developed corresponding protection programs according to the fan operating characteristics of various scenarios, enhancing safety Protective measures can realize overload protection, temperature protection and overvoltage protection, protection against collision and severe dynamic imbalance;
5. Intuitive operation interface allows users to directly operate without reading the user manual at a glance.

Remark
Regarding the noise test: under the condition that the rotation plane of the fan blade is> 8 meters from the ground and the rotation plane of the fan blade is> 2.5 meters from the roof, the vertical distance of the vertical line of the fan is 7 meters, and the sampling is carried out at a plurality of circumferentially distributed positions at a height of 1.7 meters on the ground Obtained reference noise data (the geometry of the roof and whether there are pillars around it will affect the noise test)
About comfort index characteristics
1. The fan produces wind speeds between 0.6m/s-2m/s
2. The ambient temperature is between 20 and 33℃
3. The relative humidity of the environment is between 50% and 85%
