FG3G450-48PL-2L Axial Fan, 24VDC, 450mm, 4735 m3/h

When your ventilation system must deliver industrial-scale airflow without sacrificing acoustic comfort, the FANOVA FG3G450-48PL-2L axial fan emerges as the definitive solution. This 450 mm powerhouse moves up to 4735 m3/h of air while operating at a whisper-quiet 61.2 dB(A), a level below normal conversation that makes it ideal for noise-sensitive medical, laboratory, and office environments. Engineered around a 24 VDC brushless DC motor (BLDCDC102), this fan combines the safety of low-voltage operation with the flexibility of solar, new energy, and off-grid power systems. The large-diameter impeller, crafted from glass-fiber-reinforced polypropylene, delivers high airflow at a modest 1050 RPM, ensuring extended bearing life and reduced wear. With a maximum static pressure of 137 Pa, it handles moderately restrictive ducting and filters with ease. The die-cast aluminum housing provides robust structural integrity, while the 20 AWG, 500 mm cable simplifies installation. This single fan can replace multiple smaller units, cutting system cost and complexity. Backed by FANOVA's OEM/ODM expertise and standard certifications, the FG3G450-48PL-2L is the intelligent choice for engineers demanding performance, longevity, and low-voltage safety.

The FG3G450-48PL-2L is a testament to FANOVA's advanced axial fan engineering, purpose-built for applications where high volumetric flow and low acoustic signature are non-negotiable. At its core lies a 24 VDC brushless DC motor (model BLDCDC102) with a rotor diameter of 102 mm, delivering a rated power of 168 W at a current draw of 7.0 A. The motor operates across a wide input voltage range of 16 to 28 VDC, providing compatibility with fluctuating DC supplies typical of battery and solar installations. Speed is governed at 1050 RPM, a deliberate low-speed design that minimizes noise and maximizes operational lifespan while still generating a maximum airflow of 4735 m3/h (2786.5 CFM) and a static pressure of 137 Pa (0.55 in.wg). The impeller, with a substantial 450 mm diameter, is molded from polypropylene reinforced with glass fiber, offering an excellent strength-to-weight ratio, inherent chemical resistance, and lightweight characteristics that reduce strain on mounting structures. The end caps and housing are constructed from die-cast aluminum, ensuring excellent heat dissipation and mechanical rigidity in demanding environments. Bearing life is extended through the low-speed, high-volume design philosophy, reducing thermal and mechanical stress. The fan incorporates electronic speed control interfaces compatible with PWM or analog voltage signals, allowing precise airflow modulation for dynamic system requirements. Protection features include reverse polarity and locked-rotor safeguards, alongside standard insulation for low-voltage DC applications. The electrical interface consists of a 20 AWG cable with a 500 mm length, sufficient for direct connection to control boards or power distribution units. This model is manufactured under FANOVA's rigorous quality management systems, meeting CE and RoHS directives, and is available for OEM/ODM customization including special connectors, coating options, and tailored performance curves. Its combination of high airflow, low noise, and 24 VDC safety makes it a superior choice for HVAC, agricultural ventilation, battery cooling, and renewable energy systems.

DC Axial Fan
Type	FG3G450-48PL-2L
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 FG3G450-48PL-2L delivers 4735 m3/h at 137 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 450mm 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.

5. Easy Installation and Maintenance: Compact 450mm footprint, 0-10VDC/PWM speed control, FG tach output and standard cable make the fan simple to wire, control and service.
