4-68 Series Centrifugal Fan
Backward-airfoil centrifugal fan for clean-air ventilation, dust removal and waste-gas treatment in factories and large buildings.
Yosinda manufactures industrial fans in Wuhu, China, supporting equipment buyers, engineering companies, distributors and project contractors. Our range covers centrifugal fans, axial fans, mixed flow fans, grain ventilation fans, fire smoke exhaust fans and industrial air circulators for industrial and commercial air movement.
We help match the fan configuration to the required airflow, pressure, temperature and installation conditions. OEM production can include motor and voltage customization, material selection, outlet direction, mounting and branding. Availability is confirmed for the selected model and operating point. Browse the published models below, review their technical specifications, or send your project requirements to our engineering team for selection support. Final performance and electrical specifications are confirmed before production.
