IP55-rated AC fans from Orion Fans are designed for dusty or moist environments, enabling their use in several applications including certain HVAC equipment, blowers, medical, industrial machinery, wind power devices, and remote antenna installations. The IP55-rating indicates protection from dust and water-jet spray from all directions. This rating is achieved by applying special sealing to wires, joints, and control circuitry, giving these fans a high degree of water resistance allowing outdoor use for many fans that could previously only be specified for an indoor environment. The IP55-rated AC fans also utilize a dual ball-bearing design that maximizes air flow while minimizing noise levels.
