In the industrial field, the protection level is usually expressed by IP followed by two numbers, and the first number indicates the range of dust resistance of equipment or the degree of people's protection from hazards in a sealed environment.Represents the level of preventing solid foreign bodies from entering, and the highest level is 6; The second digit indicates how waterproof the equipment is.Represents the level of preventing water ingress, with the highest level being 9.

IP is a protection grade system, and the numbers are used to specify the protection grade.the first digit indicates the range of dust resistance of the equipment, and the second digit indicates the waterproof degree of the equipment.this IP55 motor can completely prevent the intrusion of foreign objects.although it cannot completely prevent the intrusion of dust, the intrusion of dust will not affect the normal operation of electrical appliances, and it can also prevent the injection of water and low-pressure water spray lasting at least 3 minutes.

The electronic part of the cooling fan is coated with parylene nano-film, which can achieve the insulation effects of moisture-proof, water-proof, dust-proof, acid and alkali resistance and high voltage resistance, and can meet the relevant requirements of international IP grade.It is the best waterproof and moisture-proof treatment method so far.Perrin nano waterproof, compact and pinhole-free, and the protective effect is completely solved.Perrin protective coating is widely used in cooling fans in automobile, control electrical, military equipment, outdoor household appliances and other fields.
