FG3G500-48PL-20 Axial Fan, 48VDC, 500mm, 5250 m3/h

Introducing the FANOVA FG3G500-48PL-20, a high-performance axial fan engineered to deliver exceptional airflow while maintaining whisper-quiet operation, making it the ideal choice for modern HVAC and ventilation systems. This 48VDC model, part of the FG3G series, produces a massive maximum airflow of 5250 m3/h (3089.6 CFM), allowing a single fan to replace multiple smaller units, thereby reducing system complexity and installation costs. Despite its powerful output, the fan operates at just 59 dB(A), quieter than a normal conversation, which is perfect for noise-sensitive environments like medical facilities, laboratories, and open-office spaces. The fan achieves this efficiency through its large 500 mm impeller, constructed from glass-fiber reinforced polypropylene, offering a lightweight yet durable solution that resists chemical corrosion. At a low speed of 900 RPM, this design ensures minimal vibration and extended operational life for the die-cast aluminum housing and BLDC motor. The motor, rated at 168W with a 48V DC input (operating range 36-57V), aligns perfectly with telecom industry standards, enabling seamless integration into DCIM systems and battery-backed power architectures. Speed control is fully variable, allowing precise air volume regulation to match dynamic load requirements, while the motor features advanced protection against over-voltage, under-voltage, and over-temperature. The fan is equipped with high-quality bearings rated for long life, ensuring reliability in continuous-duty applications. Typical applications include data center cooling, telecom shelters, ventilation for industrial equipment, and battery energy storage systems. The FG3G500-48PL-20 is certified to meet international standards, ensuring safe and compliant operation, and represents a premium OEM/ODM solution from FANOVA for clients seeking energy-efficient, low-noise air movement.

The FANOVA FG3G500-48PL-20 is a sophisticated axial fan designed for demanding airflow applications where high volume, low noise, and DC power compatibility are critical. At its core, the fan features a 500 mm diameter impeller composed of polypropylene reinforced with glass fibers, a material choice that provides an excellent strength-to-weight ratio, inherent corrosion resistance, and dimensional stability even under varying humidity and temperature conditions. The impeller is aerodynamically optimized with a specific blade count and pitch to maximize static pressure generation and airflow efficiency at a moderate rotational speed of 900 RPM, which significantly lowers acoustic emissions and mechanical wear. This large-diameter, low-speed design philosophy allows the fan to move an impressive 5250 m3/h (3089.6 CFM) of air while maintaining a static pressure capability of 70 Pa (0.28 in.wg), making it suitable for systems with moderate duct resistance or filter loads. The drive system is a brushless DC motor (BLDCDC102) with a rotor diameter of 102 mm, delivering 168 W of shaft power with a nominal current draw of 3.5 A. The motor operates on a 48 VDC supply with a wide input voltage range of 36 to 57 VDC, which is fully compatible with standard telecom -48V rails, industrial DC buses, and battery banks, allowing for direct integration without additional power conversion stages. The motor is electronically commutated and features a built-in controller that provides variable speed control via a PWM input signal or a 0-10 V analog interface (wiring options available), enabling precise airflow modulation for demand-based ventilation strategies. For protection, the motor includes reverse polarity, over-current, over-voltage, and over-temperature safeguards, and the complete assembly is sealed to an IP55 rating, guarding against dust ingress and water splashes, which qualifies it for use in outdoor or wash-down environments. The housing is precision die-cast from aluminum alloy, offering superior heat dissipation, structural rigidity, and resistance to environmental degradation, while the end caps are designed for easy mounting in various orientations. The fan is wired with an 18 AWG cable of 135 mm length, terminated for straightforward connection to a controlled power source. The bearing system employs dual ball bearings, which are pre-lubricated and sealed to provide an operational life of over 50,000 hours at rated conditions, minimizing maintenance intervals. Each fan undergoes rigorous testing for performance, vibration, and noise to ensure compliance with quality standards, and the unit is certified under CE and RoHS directives, with options for UL recognition upon request. With FANOVA's OEM/ODM expertise, the FG3G500-48PL-20 can be customized for specific cable lengths, connectors, or control protocols to meet unique integration needs, delivering a reliable, high-efficiency fan solution for telecom, data center, and industrial ventilation applications.

DC Axial Fan
Type	FG3G500-48PL-20
Model	BLDCDC102

Ⅰ.When taking out the fan, do not directly lift the fan lead wire. If the lead wire is excessively stressed, the internal welding part may fall off

Ⅱ.Do not plug or unplug the fan lead plug when the fan is running

Ⅲ.If the fan does not work after starting, do not touch the impeller, rotor, or other parts, professional technical personnel are required to inspect the fan to prevent sudden start of the fan from causing hand or other personal injury

Ⅳ.The power line and control line of the fan cannot be connected in reverse, otherwise it will burn out

Ⅴ.Because of the soft start characteristics of the fan, to prevent personal injury, do not touch the impeller or other parts of the fan during powered on or running at low speeds

Ⅵ.The fan needs to be operated and used under the guidance of professional personnel to prevent children from coming into touch this product

Ⅶ.If the power line is worn or damaged, it needs to be returned to the manufacturer for repair or be replaced under the guidance of the manufacturer

Ⅷ.As a part of the fan, it is not recommended to use the motor alone when there is no impeller or loading

1. High Efficiency: The FG3G500-48PL-20 delivers 5250 m3/h at 70 Pa while drawing only 168W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 500mm galvanized steel sheet impeller resists corrosion, wear and high temperatures, making the fan suitable for harsh industrial environments and corrosive gas streams.

3. Wide Application Range: Suitable for industrial ventilation, dust extraction, HVAC units, agricultural ventilation and new-energy equipment, offering flexible customized solutions (OEM/ODM).

4. Sustainable Development: Low-voltage DC operation enables direct solar and battery integration; recyclable steel impeller and optimized BLDC drive meet eco-friendly requirements with long-term reliability.
