Centrifugal fan impellerCharacteristics:
Working Principle: The kinetic energy is transferred to the gas by rotating the impeller so that the gas flows out in the radial direction.
Applications: Widely used in air-conditioning systems, industrial ventilation, dust removal systems and other applications that require high pressure head.
Design form:
Front curved blades: Suitable for low pressure and high flow conditions.
Backward curved vane: Suitable for medium pressure and medium flow conditions with high efficiency.
Radial blades: For handling airflow containing particulate matter, such as dust extraction or material conveying systems.
Axial Fan Impellers
Features:
Principle of operation: Airflow enters and exits through the impeller in a direction parallel to the shaft, mainly used for high-flow, low-pressure applications.
Applications: Commonly used in cooling towers, large building ventilation, household appliance fans and other areas.
Design form:
Fixed pitch: Simple structure, low cost.
Adjustable pitch: Able to adjust the blade angle according to the actual demand to optimise performance.
