Air handling units (AHUs) are an essential part of modern HVAC systems. They regulate and circulate air in commercial buildings, factories, and clean environments, ensuring that indoor air quality and comfort are maintained at optimal levels. At the heart of most AHUs lies the AC centrifugal fan—a reliable component responsible for delivering stable airflow under varying operating conditions.
Key Reasons for Using AC Centrifugal Fans in AHUs
Stable and High Airflow
AC centrifugal fans are designed to generate consistent airflow even when operating against resistance in ducts and filters. This makes them well-suited for AHUs, where airflow stability is crucial to maintain temperature and humidity control.
Strong Pressure Capability
Unlike axial fans, centrifugal fans are capable of producing higher static pressure. This feature allows them to overcome pressure drops caused by filters, coils, and dampers inside AHUs, ensuring efficient air distribution throughout the system.
Reliable Performance and Long Service Life
AC centrifugal fans have a proven track record of durability. With robust impeller designs and stable AC motors, they provide long-term operation with minimal maintenance—an important consideration for large-scale HVAC systems where downtime can be costly.
Energy Efficiency
Modern AC centrifugal fans are designed with aerodynamic impellers and optimized housings to reduce energy losses. This not only lowers operating costs but also supports the growing demand for sustainable building solutions.
Wide Range of Applications
From office buildings and shopping malls to hospitals and industrial facilities, AHUs equipped with AC centrifugal fans can adapt to different air quality requirements. Their versatility makes them a preferred choice for HVAC system designers and contractors worldwide.

FAQ: AC Centrifugal Fans in Air Handling Units (AHUs)
- Q: Why are AC centrifugal fans better for AHUs compared to axial fans?
A: AC centrifugal fans can generate higher static pressure, which allows them to handle resistance from filters, coils, and ductwork inside AHUs. Axial fans are good for free-flow ventilation, but centrifugal fans ensure stable airflow in complex HVAC systems.
- Q: How do AC centrifugal fans improve air quality in AHUs?
A: By maintaining constant airflow through filters and cooling/heating coils, AC centrifugal fans help remove dust, control humidity, and deliver clean, conditioned air to indoor spaces.
- Q: Are AC centrifugal fans energy-efficient?
A: Yes. Modern AC centrifugal fans are designed with optimized impellers and housings that minimize energy loss, making them efficient and cost-effective for long-term operation.
- Q: What maintenance do AC centrifugal fans require in AHUs?
A: Regular cleaning of the impeller and housing, checking for motor wear, and ensuring that filters in the AHU are not clogged will help extend the fan’s lifespan and maintain performance.
- Q: Does LONGWELL provide customized AC centrifugal fans for AHUs?
A: Yes. LONGWELL offers a wide range of models and can provide tailored solutions based on airflow, pressure, and installation requirements. Learn more: https://www.longwellfans.com
