What are the common primary materials used in cabinet-type smoke exhaust centrifugal fans?

The primary materials for cabinet-type smoke exhaust centrifugal fans refer to the main components used in manufacturing the equipment. For instance, the materials for the fan's casing, impeller, and inlet. Currently, numerous material options exist. To meet diverse operational requirements, material analysis is essential during the selection and manufacturing of centrifugal fan equipment. Traditionally, carbon steel—commonly referred to as carbon steel—has been the primary material for manufacturing cabinet-type centrifugal exhaust fans. This specifically denotes iron-carbon alloy steel with a carbon content below 2.11%. Among these, Q235B is widely used due to its ease of processing and cost-effectiveness. It suits most applications involving ambient-temperature media that are dust-free and non-corrosive. Two common materials are fiberglass reinforced plastic (FRP), commonly known as fiberglass. This material is typically used for corrosion-resistant centrifugal fans. Essentially a type of fiberglass, it consists of a matrix reinforced with glass fibers, such as unsaturated phenolic resin. This material exhibits excellent corrosion resistance, withstanding various acids, alkalis, and salts. The third common material is stainless steel. In fact, stainless steel is widely used in our daily lives. It encompasses different categories, such as martensitic, austenitic, ferritic, and duplex stainless steel materials. These materials are commonly used as primary components in cabinet-type smoke exhaust centrifugal fans, offering both corrosion resistance and high-temperature tolerance. Beyond these three common materials, specialized and composite options exist, including plastics, titanium alloys, steel-lined plastics, and steel-lined fiberglass. In summary, numerous materials serve as primary components for cabinet-type centrifugal exhaust fans. Selection should be determined based on specific application requirements.
