Shenzhen Fengwang Electronics Co., Ltd. is a cooling fan manufacturer that focuses on providing high-efficiency energy-saving heat-dissipation solutions based on innovation. It has been working in the cooling fan field for more than 6 years. Fengwang has applied the latest dustproof and waterproof patented technology to IP68 series fans and achieved mass production. Our IP68 series fans can meet customer's cooling system in harsh environments such as desert, polar regions, mountains and seashores. Steady time operation, providing efficient heat dissipation.
The following will briefly introduce the knowledge of IP protection level:
IP is the abbreviation of Ingress Protection, and the IP rating is for the protection level of foreign materials in the enclosure of electrical equipment. The source is the standard of IEC 60529 of the International Electrotechnical Commission. This standard was also adopted as the US national standard in 2004. In this standard, for the protection of foreign objects on the outer shell of electrical equipment, the IP level format is IPXX, where XX is two Arabic numerals, the first marked number indicates the level of contact protection and foreign object protection, and the second marked number indicates the level of waterproof protection. IP is internationally used to identify the protection class. The code IP class consists of two digits. The first digit indicates dust, and the second digit indicates water resistance. The larger the digit, the better the protection and the like.
China's relevant test is based on the GB 4208-2008/IEC 60529-2001 "Enclosure Protection Level (IP code)" standard requirements, the conformity assessment of the shell protection grade for all types of products; the highest detection level IP68. Conventional product inspection levels include: IP23, IP44, IP54, IP55, IP65, IP66, IP67, IP68.
The first one indicates the dust prevention index:
A code system that indicates the degree of protection of the enclosure from human access to hazardous parts, prevention of the entry of solid foreign matter or water, and additional information related to these safeguards.

1 |
Prevent the invasion of solid foreign objects larger than 50mm |
Prevents the human body (such as the palm) from touching the parts inside the appliance due to accidents, preventing the intrusion of foreign objects of larger size (diameter greater than 50mm) |
2 |
Prevent the intrusion of solid foreign objects larger than 12.5mm |
Prevents human fingers from coming into contact with parts inside the appliance to prevent intrusion of foreign objects of medium size (>12.5mm in diameter) |
3 |
Prevent the intrusion of solid objects larger than 2.5mm |
Prevents intrusion of tools, wires, and similar small foreign objects with a diameter or thickness greater than 2.5 mm into contact with parts inside the appliance |
4 |
Prevent the penetration of solid foreign objects larger than 1.0mm |
Prevents intrusion of tools, wires, and similar small foreign objects with a diameter or thickness greater than 1.0 mm into contact with parts inside the appliance |
5 |
Prevent foreign objects and dust |
Completely prevent the intrusion of foreign objects, although not completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of electrical appliances |
6 |
Prevent foreign objects and dust |
Completely prevent the intrusion of foreign objects and dust |
The second position indicates the waterproof index:

No special protection against water or moisture |
1 |
Prevent water intrusion |
Dropped drops of water (condensed water, for example) will not cause damage to the appliance |
2 |
When tilted at 15 degrees, water droplets can still be prevented from intruding |
When the appliance inclines vertically to 15 degrees, the water will not damage the appliance |
3 |
Prevent the intrusion of sprayed water |
Prevents rain or water from intruding into appliances with a vertical angle less than 60 degrees to cause damage |
4 |
Prevent splash water intrusion |
Prevents splashing water in all directions from entering the appliance and causing damage |
5 |
Prevent the intrusion of sprayed water |
Prevents water from the nozzles from coming from all directions from entering the appliance and causing damage |
6 |
Prevent large waves from intruding |
Electric appliances installed on the deck prevent damage caused by large waves |
7 |
Prevent water ingress during flooding |
The electric appliance is immersed in water for a certain period of time or the water pressure is below a certain standard to ensure that it is not damaged due to flooding |
8 |
To prevent the intrusion of water when sunk |
The appliance sinks indefinitely under the specified water pressure, ensuring no damage due to flooding |
