Industrial Cooling Fan is widely used, and its application environment is also different. In outdoor, humid, dusty and other harsh environments, the General Cooling Fan has a waterproof level, namely IPxx, the so-called Ip is the abbreviation of Ingress Protection, Ip level is against foreign invasion, dust, waterproof and collision Protection level. The level of protection is usually expressed in terms of intellectual property rights and two numbers, which are used to specify the level of protection. The first number indicates the dust-proof range of the equipment. I stands for the level of prevention of the entry of solid foreign bodies, the highest level being 6. The second number indicates the degree of water resistance. P stands for waterproof grade, the highest grade being 8. For example, the heat sink fan is rated IP54. IP54 is the most basic cooling fan waterproof grade, referred to as the three anti-paint. The process is to impregnate the entire printed circuit board. The highest waterproof rating a fan can achieve is IP68, which is vacuum coated or filled with glue to completely insulate it from the outside world. Dust level digital protection is defined as no protection, no special protection 1 to prevent the intrusion of objects larger than 50 mm, to prevent accidental human contact with the fan interior, to prevent the intrusion of objects larger than 50 mm diameter. 2 avoid the intrusion of objects larger than 12 mm, avoid fingers touching the inside of the fan, 3 avoid the intrusion of all objects larger than 2.5 mm, and avoid the intrusion of special tools, wires or objects larger than 2.5 mm directly. 4 to prevent the invasion of objects larger than 1.0 mm, to prevent mosquitoes, flies, insects or objects larger than 1.0 mm in diameter. Anti-dust can not completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of power. The dust completely prevents the dust from invading the waterproof grade number, the degree of protection, the definition does not have the protection, does not have the special protection 1 to prevent the water drop from invading and falling vertically 2 when the fan tilts 15 degrees, can still prevent the water drop from invading. 3 avoid the intrusion of Sprinkler Water, avoid precipitation or water at a vertical intersection angle of less than 50 degrees from the direction of the sprinkler. Avoid Water SPLASHES, avoid water splashes to invade in all directions 5 in order to prevent the big waves into the water, prevent the big waves or the spout to quickly invade the water. In order to avoid the leakage of water in strong wind and waves, the fan may leak water in a certain time or under the pressure standard, but it can still ensure the normal operation of the fan And can guarantee the fan normal operation 8.
