1. Pay attention to coverage area

The high power of newly launched large electric fans also indicates that their speed is fast, so the air volume is large. In theory, they are indeed proportional to each other, but practical products often cannot be completely equated. For example, some large electric fans may have high power, but their wind speed is low due to the structural constraints of the blades and other power systems. The connections between them are chaotic, so when choosing a large electric fan, you can directly check whether it has a super large coverage area to determine its wind speed and power.

2. Check if high-altitude devices are simple

A large electric fan is different from a typical home electric fan. It not only requires assembly, but also requires a hanging device. Therefore, when choosing a well-known large electric fan in China, it is also necessary to consider whether it will save space when installed at high altitudes. For some workshops with relatively small factory areas and relatively high ceilings, it is important to pay more attention to this when selecting a large electric fan.

3. Check for corrosion resistance

If you want to ensure the service life of a large electric fan, the editor suggests choosing magnesium aluminum alloy blades, and it is best to choose a blade chassis (high-density die-casting aluminum alloy or using a machining center for one-time processing and forming is the best). It is now one of the most corrosion-resistant and durable types in the industry.

In addition, when selecting a large electric fan, attention should also be paid to its deceleration system, such as whether the drive deceleration motor is specially modified for the operating characteristics of industrial electric fans. Finally, large electric fan manufacturers remind everyone to pay attention to whether to choose mainstream brand frequency converters as the basic configuration for frequency converter speed regulation. It is necessary to consider its safety requirements and safety facility requirements, and select suitable large electric fan products for enterprise workshops.
