About AC Centrifugal Fan

AC centrifugal fans (also called AC centrifugal blowers) use AC induction motors to drive impellers that accelerate air radially outward, creating significantly higher static pressures than axial fans can achieve. This makes them essential for applications requiring air to be pushed through ductwork, filters, or heat exchangers with substantial pressure drop. AC centrifugal fans come in two primary configurations: forward-curved impellers for high airflow at moderate pressure, and backward-curved impellers for higher efficiency and pressure capability. They are used extensively in HVAC air handling units with long duct runs, industrial dust collection systems, fume extraction, combustion air supply for boilers and furnaces, and air curtain systems. Important selection parameters include fan curve matching to system resistance, motor power rating, impeller diameter, and construction material (galvanized steel, stainless steel, or plastic). Hengrui supplies AC centrifugal fans from all major global brands including ebm-papst, ZIEHL-ABEGG, Rosenberg, Nicotra Gebhardt and SODECA, with full product specification sheets and engineering support.

Bag

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.
