Protection level:
For wet, corrosive (or outdoor), flammable and explosive, and other places, the use of cooling fans, should choose to have the corresponding protective measures to ensure that the system (including the fan itself) was destroyed. For example: for humid environment, should choose with moisture proof processing products; for the application environment of water or water, it should choose a IP55 level products; for inflammable and explosive places, to be elected in the use process, and can not produce sparks or product itself burst, combustion products.
A.Explosion-proof
The motor is sealed by a thermosetting plastic grease, the motor winding and the PCB with the electronic part is isolated from the Environment.
