Waterproof cooling fan IP protection grade and salt spray test
: salt mist salt spray corrosion resistance experiment of metal surface treatment.
waterproof cooling fans are highest IP68 protection grade, such as fan doesn't work of flooding, choose IP55 ( Even from multiple directions of flow direct injection under the bad environment of steady operation) Can, can meet the waterproof moisture-proof/dustproof function.
restricted by cooling fan structure, Japanese fan, table fan, domestic fan is the highest level IP68 fan is only in view of the fan electronics; Fan structure metal magnetic field device, core shaft, bearing no IP protection.
/ bearing/axial magnetic box unprotected IP68 protection only for electronic devices do
a cooling fan to resistance to salt fog, except the stator magnetic field, bearing are required to do special craft processing, at present, do not make special craft processing, 4 - salt spray test When 8 hours, not bad, but the stator magnetic field, bearing special selection and processing, can be more than 14 consecutive days.
chi auto focus a cooling fan field, to provide professional technical support, product collaborative design according to user needs, provide the overall cooling solutions.
