Small centrifugal fans are compact, high-static-pressure air-moving devices, and their main application scenarios cover the following fields: ‌Agricultural & Material Conveying‌ They are widely used in grain drying, grain storage aeration, and the pneumatic conveying of light bulk materials such as grains, raw cotton, sawdust and plastic pellets. In cotton ginneries, they can extend the effective working range of pneumatic conveying systems to transport raw cotton over long distances between workshops, while preventing grain spoilage and maintaining crop quality. ‌Industrial Manufacturing & Ventilation‌ They serve for fume extraction in workshops, dust removal in dust collectors, supplying combustion air for industrial furnaces, and propelling abrasive media in blasting equipment. These functions help improve on-site air quality, reduce fire risks, boost processing efficiency and meet OSHA safety compliance requirements. ‌HVAC & Building Air Systems‌ They are integrated into air handlers, fan coil units and rooftop units, efficiently pushing conditioned air through ductwork and filters. They can reduce indoor humidity buildup, optimize air circulation, and are suitable for ventilation scenarios in homes, offices and medical facilities.
