The 230V EC 280mm 370W Backward Centrifugal Fan combines energy efficiency and high performance to meet the demands of heavy-duty industrial applications. Equipped with an electronically commutated (EC) motor, this fan integrates AC power input with DC motor efficiency, offering precise speed control and significant energy savings compared to traditional AC fans. Its 280mm backward-curved impeller is designed to generate high static pressure, making it suitable for systems with high air resistance, such as commercial HVAC units, industrial fume extraction systems, and cleanroom ventilation. The EC motor's built-in electronics enable seamless integration with building management systems, enhancing operational flexibility.
The EC motor combines the efficiency of DC motors with the convenience of AC power, delivering 30-50% higher efficiency than traditional AC induction motors across a wide range of operating speeds. This reduces energy consumption and lowers carbon emissions .
The backward-curved impeller generates 635 Pa of static pressure at 2,700 RPM, making it capable of pushing air through long duct runs, high-efficiency filters, and heat exchangers with minimal airflow loss .
Supports multiple control protocols, including 0-10V, PWM, and Modbus RTU, allowing integration with smart building systems for automated speed adjustment based on real-time demand.
Advanced aerodynamic design of the impeller and motor housing reduces airflow turbulence, while the EC motor’s smooth operation minimizes electromagnetic noise, resulting in levels as low as 67 dB(A) .
The fan features double-sealed ball bearings rated for 50,000+ hours of operation, while the IP55-rated enclosure protects internal components from dust and water jets, ensuring reliability in harsh environments.
HVAC Systems: Used in rooftop packaged units, commercial kitchen exhaust systems, and cleanrooms (ISO 7-8 classification), where precise airflow control is critical.
Industrial Ventilation: Deployed in chemical processing plants, paint booths, and metalworking facilities to extract fumes, particulate matter, and excess heat.
Data Centers: Integrated into precision cooling systems for high-density server rooms, where variable speed operation matches cooling output to heat load.
Agriculture: Employed in large-scale greenhouse climate control systems to circulate air through CO₂ injection systems and evaporative coolers.
Q: What is the EC motor's lifespan?
A: The EC motor is rated for 100,000+ hours of operation under normal conditions, with minimal performance degradation over time due to its brushless design.
Q: Can it be used in explosive environments?
A: No, the fan is not certified for hazardous locations (ATEX or UL Class I/II). For explosive environments, consider specialized explosion-proof models with sealed motor enclosures.
Q: How does the EC motor compare to AC motors?
A: EC motors maintain high efficiency across a wider speed range (30-100% of rated speed), whereas AC motors often lose efficiency at partial loads. This makes EC motors more energy-efficient in applications with variable airflow demands .
Q: Does the fan include a speed controller?
A: The fan includes a built-in motor controller with basic speed adjustment, but advanced features (such as remote monitoring or BMS integration) require a compatible external controller (sold separately).
