Centrifugal fans are the workhorse of high-pressure industrial ventilation, using curved impellers to accelerate air radially outward and convert velocity to pressure. This operating principle enables centrifugal fans to overcome substantial system resistance — making them essential for ducted HVAC systems, dust collection and fume extraction systems, combustion air supply, and industrial process ventilation. Centrifugal fans are classified by impeller geometry: forward curved (high airflow, moderate pressure), backward curved (high pressure, maximum efficiency), or radial blade (rugged construction for particulate-laden airflow). They are also available in direct-driven or belt-driven configurations. Centrifugal fans operate across a wide range of motor types and speeds — from 1500 RPM standard AC motors to high-speed EC drives. Key manufacturers include ebm-papst, ZIEHL-ABEGG, Nicotra Gebhardt, Rosenberg, and SODECA. Hengrui supplies centrifugal fans from all major brands with complete performance curves, competitive pricing, and engineering consultation for system design. When selecting centrifugal fans, engineers must match fan performance curves to calculated system curves for optimal efficiency and reliability.

Bag packaging indicates that a specified quantity of product is packaged by the manufacturer in a bag, sealed pouch, or similar container and sold as a unit without repackaging. It is also used to describe kits/assortments where components are packaged in separate bags according to part number or parametric value, rather than in a compartmentalized box or similar rigid container.
