Industrial cooling fans are widely used, and the application environment is also different.
In harsh environments, such as outdoor, humid, dusty and other places, general cooling fans have a waterproof rating, which is IPxx.
The so-called IP is Ingress Protection.
The abbreviation for IP rating is the degree of protection against the intrusion of foreign objects in the enclosure of electrical equipment, dustproof, waterproof and anti-collision.
The protection level is usually expressed by two numbers followed by IP, and the numbers are used to clarify the protection level.
The first number indicates the anti-dust range of the equipment.
I represents the level of preventing solid foreign objects from entering, and the highest level is 6;
The second number indicates the degree of waterproofing.
P represents the level of preventing water ingress, and the highest level is 8. For example, the protection level of the cooling fan is IP54.
Among the cooling fans, IP54 is the most basic waterproof level, referred to as the three-proof paint. The process is to impregnate the entire PCB board.
The highest waterproof level that the cooling fan can achieve is IP68, which is vacuum coating or the glue is completely isolated from the outside world.
Protection Degree Definition No protection No special protection Prevent the intrusion of objects larger than 50mm.
Prevent the human body from accidentally touching the internal parts of the fan.
Prevent the intrusion of objects larger than 50mm in diameter.
Prevent the intrusion of objects larger than 12mm and prevent fingers from touching the internal parts of the fan.
Prevent all intrusion of objects larger than 2.5mm
Prevent the intrusion of tools, wires or objects larger than 2.5mm in diameter Prevent the invasion of objects larger than 1.0mm.
Prevent the invasion of mosquitoes, insects or objects larger than 1.0 Dust-proof can not completely prevent the intrusion of dust, but the amount of dust invaded will not affect the normal operation of the electrical.
Dustproof Completely prevent dust intrusion Waterproof rating Number Protection Degree Definition No protection No special protection.
Prevent the intrusion of drips and prevent vertical dripping.
Prevent dripping when tilted 15 degrees.
When the fan is tilted 15 degrees, dripping can still be prevented.
Prevent the intrusion of sprayed water, prevent rain, or the water sprayed in the direction where the vertical angle is less than 50 degrees.
Prevent the intrusion of splashing water and prevent the intrusion of splashing water from all directions.
Prevent the intrusion of water from large waves, and prevent the intrusion of water from large waves or water jets rapidly.
Prevent the water intrusion of big waves. The fan can still operate normally when the fan penetrates into the water for a certain period of time or under water pressure conditions.
To prevent the intrusion of water intrusion, the fan can be submerged indefinitely in the water under certain water pressure, and can ensure the normal operation of the fan.Prevent the effects of sinking.
