Cabinet-Type Centrifugal Exhaust Fans for Material Handling

Cabinet-Type Centrifugal Exhaust Fans for Material HandlingCabinet-type centrifugal exhaust fans for material processing handle materials with high static pressure in the air. Their robust design does not compromise wheel integrity but shifts the weight of the air onto the viscous grinding material. Currently, two distinct impeller types are available for centrifugal fans used in material processing. One features an open radial blade design. The second type also employs a radial blade configuration but incorporates a backplate. This design prevents direct motor drive to the fan, facilitating smooth airflow and material entry into the fan. Below is a brief overview of the characteristics of cabinet-style exhaust centrifugal fans for material handling. First, from a performance and design analysis perspective, the material handling airflow capacity of this specialized cabinet-style exhaust centrifugal fan can reach 80,000 cfm (higher output and custom designs are available). Maximum 45-inch WG static pressure (custom designs for higher pressure); temperatures up to 1200°F; open rod design. Second, cabinet-style exhaust centrifugal fans are primarily applied in material handling for the following areas: General material handling equipment, dust collection systems, air conveying systems. Anti-pollution equipment; boiler ash removal systems; cyclones; Skeleton Bar; dryers; heat exchangers; drum dryers; gas and odor control systems; bulk material conveying systems; air classifiers; hammer mills; Material Analysis of Material Handling Cabinet-Style Exhaust Centrifugal Fan Structures: Currently, when manufacturing cabinet-type exhaust centrifugal fans, impellers can be fabricated from various materials encompassing either a portion of the airflow path or the entire centrifugal fan assembly. Materials suitable for applications involving high operating temperatures, corrosive contaminants, or explosive environments include carbon steel grades, all-stainless steel, nickel-based alloys (e.g., 625, C22, C276), and titanium.
