Whether the cooling fan can pass the salt spray test is mainly related to the structure and process of the cooling fan. The final goal is the structure or the process to protect the motor and resist the interference of water mist and salt spray.
It is better to seal the entire motor so that the salt mist cannot enter the inner motor, and the plastic outer frame and leaves are okay to pass the salt mist. For larger specifications, such as a cooling fan above 8025, it is possible to deal with the structure in this way. However, it is much more difficult for a cooling fan with a thin size such as 10MM or less.
For thin cooling fans, the current better way to resist salt spray is motor vacuum coating, PCB boards, copper wires, electronic components, etc., using higher quality, silicon steel sheets, magnetic strips, shaft cores, etc. themselves. Salt spray test. Generally, it is divided into parts for special treatment
