Forward centrifugal fans
Forward centrifugal fans have a blade exit angle of more than 90°. When working, the impeller rotates at high speed to generate centrifugal force, which throws the air from the center to the edge, and discharges it through the pressurization of the worm casing, and at the same time, negative pressure is formed inside the impeller to continuously absorb the air. Widely used in ventilation and air conditioning, industrial gas transportation, dust removal and equipment supporting and other fields, especially in the high-pressure, small air volume scenarios with outstanding advantages, can meet the needs of multi-industry gas treatment.
Backward centrifugal fans
Backward centrifugal fan in the work, the airflow from the fan axial into the blade space, and then driven by the impeller on the one hand with the impeller rotation; on the other hand in the role of inertia to improve the energy, along the radius of the direction of the impeller to leave the fan, relying on the centrifugal force generated to do the work of the fan is called centrifugal fan.
Axial Fans
Axial fan is a kind of ventilation equipment which conveys gas through axial flow, and its core impeller is composed of hub and twisted blades. When working, the motor drives the impeller to rotate, and the blades push the gas to flow along the axial direction (parallel to the direction of the rotating axis), and the gas flows directly from the inlet end to the outlet end of the fan, and the flow direction is basically unchanged, which is similar to the principle of propeller propulsion.
Duct Fans
Duct fan is a ventilation equipment designed for installation in ducts, which is composed of core components such as motor, impeller and casing. Through the centrifugal force or axial thrust generated by the rotating impeller, the air is sucked in and transported directionally along the pipeline to realize the efficient ventilation, air exchange or air conditioning function in the confined space.
Pump
Pump is a mechanical energy through mechanical energy will fluid energy (kinetic or potential energy) to enhance the mechanical device, the use of impeller rotation, piston reciprocation and other principles to change the pump volume or produce centrifugal force, drive the fluid flow, to achieve the transmission, pressurization or circulation function. According to the working principle can be divided into volumetric pumps (such as piston pumps) and vane pumps (such as centrifugal pumps) and other types.

Air Handling Unit Fan Improves Ventilation Efficiency for Modern HVAC Systems
Release time:
2026-08-20
Newest air handling unit fan spots offer efficient ventilation solutions with reliable performance, advanced design, and OEM options.
Air handling unit fan is a key component in HVAC systems designed to provide efficient air circulation, ventilation, and indoor climate control. It plays an important role in moving conditioned air through air handling units and distributing fresh, comfortable air across residential, commercial, and industrial buildings. With reliable airflow performance, energy-efficient operation, and flexible configurations, air handling unit fans help maintain stable indoor environments while supporting modern building ventilation requirements.
As buildings become more focused on energy efficiency and indoor air quality, HVAC systems need components that can deliver consistent airflow while reducing operational costs. Traditional ventilation solutions may struggle with changing airflow demands, noise control, and energy consumption. Air handling unit fans provide an effective solution by improving air movement, supporting temperature regulation, and enhancing the overall performance of air management systems.
Working Principle and Structure of Air Handling Unit Fans
An air handling unit fan works by using mechanical power to move air through the HVAC system. The fan draws air into the air handling unit, passes it through filters, cooling or heating components, and then distributes the conditioned air through duct systems.
The main structure of an air handling unit fan typically includes an impeller, motor, housing, drive system, and control components. Each part works together to generate stable airflow and maintain efficient operation.
Different fan designs are selected based on system requirements. Centrifugal fans are commonly used in air handling units because they provide strong pressure capability and stable airflow performance. Other designs may be chosen depending on installation space, airflow volume, and energy efficiency targets.
Modern air handling unit fans often use advanced motor technologies and intelligent control systems. Variable speed operation allows the fan to adjust airflow according to actual demand, improving comfort while reducing unnecessary energy consumption.
Key Advantages of Air Handling Unit Fans
One of the main advantages of air handling unit fans is reliable airflow control. They help HVAC systems maintain consistent air distribution, ensuring comfortable temperatures and improved indoor air quality.
