The selection of the protection level of the external rotor axial flow fan needs to consider many factors in the field environment to ensure the safe and stable operation of the fan. The following are some key points to determine the appropriate level of protection:

Dust and particulate level: according to the content and size of dust and particulate matter in the field environment, select the corresponding IP code. For example, if there is a lot of dust in the environment, you may need to choose IP55 or higher protection.

Moisture level: If the environment where the fan is located is humid or may be exposed to water, such as cooling towers or kitchens, it is necessary to select a protection level that can prevent moisture intrusion, such as IPX5 or IPX6.

Temperature: The operating temperature range of the fan must adapt to the temperature change of the field environment. Some fans are designed to operate in high or low temperature environments and need to be considered in the selection.

Corrosion: If there are corrosive gases or liquids in the field environment, it is necessary to choose corrosion-resistant materials and protection levels, such as stainless steel fans or fans with special coatings.

Explosive hazardous environment: in the presence of flammable and explosive gases, it is necessary to choose a fan that meets explosion-proof standards, such as EX or DII grade.

Noise and vibration: In environments with high noise or vibration requirements, you need to choose a low noise and low vibration design.

Power supply: Ensure that the power requirements of the fan match the field environment, such as voltage, frequency, etc.

Installation location: The installation location of the fan (such as indoor, outdoor, high altitude, etc.) will also affect the choice of protection level.

Operator safety: ensure that the protective measures of the fan can protect the safety of the operator, such as protective nets, fences, etc.

Maintenance and cleaning: Consider the maintenance and cleaning convenience of the fan, choose a detachable or easy-to-access design.

Considering the above factors, the protection level of the outer rotor axial flow fan suitable for the field environment can be selected to ensure the safe operation and long-term stability of the fan.
