Axial fans are the most common type of industrial ventilation equipment, with blades that rotate to move air parallel to the axis of rotation. This design makes axial fans ideal for applications requiring high airflow rates at relatively low static pressures — including general factory ventilation, condenser cooling for refrigeration and air conditioning systems, data center hot-aisle containment cooling, industrial process exhaust, and air supply for combustion equipment. Axial fans are available in both AC and EC (Electronically Commutated) versions, with EC technology providing up to 70 percent energy savings. Frame sizes range from 200mm for compact applications to over 2000mm for heavy-duty industrial use. Key specification parameters include airflow rate (m3/h or CFM), static pressure capability (Pa), noise level (dBA), and blade material (galvanized steel, aluminum, or composite plastic). Leading manufacturers include ebm-papst, ZIEHL-ABEGG, Rosenberg, and SODECA. Hengrui is authorized distributor for all major brands, offering competitive pricing, original spare parts, and engineering consultation for axial fan selection and system integration.
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.
