The 24V DC 220W 280mm Backward Centrifugal Fan is a high-performance industrial-grade solution designed for applications requiring efficient airflow management and reliable operation in complex systems. Its backward-curved blade design is engineered to convert rotational energy into directed airflow with minimal energy loss, striking a precise balance between high static pressure and consistent airflow output. This makes it particularly effective for systems with moderate to high air resistance, such as ducted HVAC systems, industrial ventilation units, and heat exchange equipment. The 24V DC motor not only ensures compatibility with low-voltage power systems commonly found in industrial settings but also contributes to lower energy consumption compared to traditional AC motors. With a 280mm diameter, the fan offers a compact footprint that fits seamlessly into space-constrained installations while maintaining robust performance.
The backward-curved impeller features aerodynamically optimized blade angles that reduce air turbulence, enabling the fan to maintain stable airflow even when pushing air through filters, long duct runs, or heat exchangers with high resistance .
The 24V DC motor incorporates brushless technology, which eliminates friction from moving contacts, reducing energy loss and extending operational life. This design cuts energy consumption by up to 30% compared to equivalent AC fans, making it suitable for continuous-operation environments .
The fan housing is constructed from galvanized steel, while the impeller uses glass-reinforced plastic (GRP) to resist corrosion and mechanical stress. Precision-balanced components minimize vibration, reducing wear on bearings and extending maintenance intervals.
Advanced aerodynamic modeling during design reduces airflow turbulence, resulting in noise levels as low as 67 dB(A)—equivalent to the sound of a typical office conversation—even at maximum operating speed .
Tested to perform reliably in ambient temperatures from -20°C to 60°C, the fan withstands extreme thermal fluctuations, making it suitable for both indoor industrial spaces and outdoor enclosures with climate control.
HVAC Systems: Integrates seamlessly into air handling units (AHUs) and variable air volume (VAV) systems, where it efficiently circulates conditioned air through multi-zone ductwork.
Industrial Equipment: Used in plastic molding machines, metal processing units, and packaging lines to dissipate heat generated by motors and hydraulic systems.
Data Centers: Deployed in server rack cooling systems to maintain optimal operating temperatures for high-density computing equipment, where consistent airflow prevents hotspots.
Agriculture: Employed in greenhouse climate control systems to circulate air through misting systems and CO₂ enrichment setups, promoting uniform plant growth.
Q: What is the maximum airflow capacity?
A: The fan delivers a maximum airflow of 1,130 m³/h at 2,700 RPM, with adjustable output via PWM control to match varying system demands .
Q: Can this fan be used in outdoor environments?
A: Yes, its IP55-rated enclosure provides protection against dust ingress and low-pressure water jets, making it suitable for outdoor installations such as rooftop HVAC units and industrial cooling towers.
Q: How do I install the fan?
A: The fan features a flange-mounted design with pre-drilled holes for compatibility with standard mounting brackets. Installation requires alignment with ductwork to minimize air leakage, and secure fastening to reduce vibration transfer to surrounding structures.
Q: What is the expected lifespan?
A: With regular maintenance (including bearing lubrication every 12 months), the fan’s ball bearings and motor are rated for 50,000+ hours of continuous operation.
