Select a coastal industrial fan by separating salt exposure, wet-dry cycling, airstream chemistry, material, coating, fasteners, drainage and maintenance access.
Coastal exposure is not one corrosion category. Outside air, process air and washdown can impose different material and coating demands on the fan and supports.
A coating claim without a surface-preparation and maintenance basis is not a complete selection. Keep the exposure, material and inspection plan in one record.
