FW3G500-4AGC-30L Axial Fan, 380VAC, 500mm, 10350 m3/h

When your ventilation system must move massive volumes of air through long ducts or high-resistance filters, the FW3G500-4AGC-30L axial fan delivers industrial-grade performance without the need for multiple smaller units. This 380VAC three-phase fan generates up to 10,350 m3/h of airflow at 1750 RPM, making it a true workhorse for demanding HVAC, agricultural, and manufacturing applications. The 500mm cold-rolled steel impeller is engineered for durability and corrosion resistance, ensuring reliable operation in harsh environments where plastic fans would fail prematurely. Powering this unit is a BLDCEC138 electronic commutated motor that delivers 900W of output while maintaining efficient operation across a wide voltage range of 304 to 456VAC. The EC motor technology enables precise speed control and superior energy savings compared to traditional AC induction motors. With a noise rating of just 79 dB(A), this fan balances high airflow with acceptable acoustic performance for industrial settings. The die-cast aluminum housing and endcaps provide excellent structural integrity and heat dissipation, extending the fan's service life. This model supports multiple control interfaces, including 0-10V PWM and Modbus RTU, allowing seamless integration into building management systems. Certified to CE and UL standards, the FW3G500-4AGC-30L is the capital equipment choice for heavy-duty ventilation projects requiring both power and longevity. Choose FANOVA for OEM/ODM axial fan solutions that meet your exact specifications and exceed performance expectations.

The FW3G500-4AGC-30L is a 500mm axial fan from FANOVA's FW3G series, specifically engineered for high-volume air movement in industrial and commercial ventilation systems. At the heart of this unit is a BLDCEC138 electronically commutated motor with a 138mm rotor diameter, operating on a three-phase 380VAC supply with an input range of 304 to 456VAC. The motor draws 1.6 amperes and consumes 900 watts at its rated speed of 1750 RPM, delivering a maximum airflow of 6090.98 CFM (10,350 m3/h). This performance enables the fan to replace multiple smaller axial fans in applications such as greenhouse ventilation, warehouse air circulation, and industrial exhaust systems.

The impeller is fabricated from cold-rolled steel sheet, a material chosen for its exceptional strength-to-weight ratio and resistance to deformation under high centrifugal loads. The 500mm diameter impeller features a carefully optimized blade geometry with a swept design that maximizes aerodynamic efficiency while minimizing turbulence-induced noise. The blade count and pitch angle are tuned to achieve the best trade-off between static pressure capability and volumetric flow, ensuring the fan can overcome resistance from ducts, louvers, and dirty filters. The steel construction provides inherent durability against abrasive particulates and incidental impacts, making it suitable for dusty environments such as grain handling, cement plants, and woodworking facilities.

The motor technology employed is FANOVA's proprietary BLDCEC (Brushless DC with Electronic Commutation) design, which replaces conventional AC induction motors with a permanent-magnet synchronous rotor and electronic driver. This architecture allows for variable speed operation through multiple control interfaces, including a 0-10V analog signal, PWM input, and Modbus RTU communication for remote monitoring and automation. The integrated speed controller enables the fan to modulate airflow based on real-time demand, achieving energy savings of up to 50% compared to fixed-speed AC fans in part-load conditions. The motor is equipped with thermal overload protection and automatic restart functionality, safeguarding against overheating and voltage transients. Insulation class H is standard, allowing continuous operation at ambient temperatures up to 60°C.

Mechanically, the fan uses a double-ball-bearing system with a design life of 50,000 hours at rated load, ensuring long-term reliability in continuous-duty applications. The bearings are sealed and pre-lubricated, requiring no maintenance during the fan's operational lifetime. The rotor and stator are balanced to ISO 1940 Grade 6.3, minimizing vibration and extending bearing service life. The housing and endcaps are manufactured from die-cast aluminum alloy, providing excellent dimensional stability, corrosion resistance, and heat dissipation. The fan is designed for either horizontal or vertical mounting, with integrated mounting flanges that accept standard fasteners. The electrical interface consists of an 18AWG cable with a length of 1000mm, terminated with a standard connector that simplifies field wiring. The cable is rated for high-flex applications and features a protective outer jacket resistant to oil and UV exposure.

Environmental robustness is a key attribute, with the fan housing sealed to IP55 standards, protecting the motor and electrical components from dust ingress and water jets. This makes the FW3G500-4AGC-30L suitable for outdoor installations, washdown environments, and coastal applications. The fan is certified to CE and UL standards, complying with the latest efficiency regulations for EC fans, including ErP 2015 and IEC 60034-30-1. Each unit undergoes 100% run-in testing to verify airflow, current draw, and vibration levels before shipment. For OEM customers, FANOVA offers customized versions of this model, including alternative voltages (e.g., 400VAC, 415VAC), different cable lengths, specialized coatings for corrosive environments, and custom connector options. The FW3G500-4AGC-30L is also available with an optional integrated tachometer output, enabling closed-loop speed feedback for precision control systems. With its combination of high airflow, industrial-grade materials, and advanced EC motor technology, this axial fan represents a superior choice for engineers designing robust ventilation solutions.
