IP Rating introduction
Usually, the waterproof cooling fan on the market refers to the cooling fan with protection level IP53 and above. Normally the protection level basically does not exceed IP56, because, excluding foreign manufacturers, there are only a few domestic manufacturers who have the technical ability to achieve IP68 protection for cooling fans. We, Mega Tech, are proud of being one of them，Our DC fans can undergo a rigorous vacuum sealing process, enabling them to operate during submersion. Here we will briefly introduce the knowledge of IP protection level as follows.

What is waterproof axial flow fans？
Generally, we believe that the waterproof fan is divided into IP55 and IP68. The waterproof fan or waterproof motor with IP55 waterproof rating has only moisture-proof function. The manufacturing method generally uses the three-proof paint on the outer surface of the motor, which has the ability of publication oxidation.
IP68 waterproof fans are generally manufactured by vacuum coating or epoxy filling.
Frist, Vacuum coating
The vacuum coating process is similar to semiconductor lithography. In a vacuum environment, atoms of the material are separated from the heating source . The material is plasticized on the surface of the object to be coated. It is also injected into the metal motor body and a layer of nanomaterial is deposited on the surface of the object. The thickness of the film layer is typically 5 to 30 microns. The electroplating process has advantages such as good heat dissipation efficiency and rapid batch manufacturing. However, nanomaterials are generally not resistant to corrosion. The film layer will peel off over time.
Second，Epoxy Resin filling
For the high requirements of waterproof products, even the requirements of the possibility of soaking in water, which is required to isolate the entire motor, so that water can not interfere with the motor, a more reliable practice is PCB plus epoxy resin. seal the motor, that can not see the motor. In the motor internal glue protects the important heart of the fan. At the same time, the fan rotor, and metal frame leaves for anti-rust treatment, so as to ensure that the fan can be dustproof, waterproof, and anti-corrosion so that it can adapt to a variety of working environments.
Comparison
The epoxy resin-sealed waterproof fan can resist corrosion, and this kind of waterproof fan needs a special mold to add waterproof function, the internal structure is well designed to do gluing, and the motor adds a special mold to protect the cover. It is also necessary to have a special mold to be able to. To do this process is to put the waterproof fan in the water work, which also does not affect the performance of the fan. Therefore, the effect of sealing the motor by grouting resin is better and makes the process more responsible, but the production speed is slower, the center motor cooling effect is a little worse, and the price is more expensive than the coating process.
The IP68 rating is important to ensure that the electronics inside the enclosure have the highest level of protection against foreign objects and water, while also protecting the user from potentially harmful exposure. Equipment installed outdoors faces high temperatures and cold, wind and sun, and other harsh weather corrosion and rust, cooling fans play a role in cooling the equipment under difficult conditions. IP68 series fans, can comfortably cope with a variety of working conditions of long-term stable work, to protect the normal operation of equipment.
