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

The FG3G450-48PL-2L axial fan is engineered to deliver industrial-grade airflow without the noise penalty typically associated with large-diameter fans. Boasting a maximum airflow of 4735 m³/h and a sound level of just 61.2 dB(A), this 450 mm unit replaces multiple smaller fans in ventilation systems while operating below conversational noise thresholds. Powered by a 24 VDC brushless DC motor (model BLDCDC102), it offers a safe low-voltage solution ideal for solar-powered, off-grid, and new energy installations. The fan draws only 7.0 A at a rated speed of 1050 RPM, consuming 168 W while generating a static pressure of up to 137 Pa. Its glass-fiber-reinforced polypropylene impeller ensures lightweight durability and chemical resistance, while the die-cast aluminum housing provides robust structural integrity. With a wide voltage range of 16 to 28 VDC, this model adapts to fluctuating power supplies common in renewable energy systems. The fan is equipped with protection features and insulation suited for demanding environments, and its 102 mm rotor uses long-life bearings for extended service intervals. Typical applications include HVAC equipment, battery cooling, solar inverters, and industrial ventilation cabinets. The FG3G450-48PL-2L carries relevant certifications, ensuring compliance with international standards for safety and performance. Choose FANOVA for a reliable, high-efficiency axial fan that combines low noise, massive airflow, and 24V flexibility in one compact package.

The FG3G450-48PL-2L represents a sophisticated convergence of aerodynamic design and electronic commutation, purpose-built for applications demanding high volumetric flow at low acoustic output. The impeller, constructed from polypropylene reinforced with glass fibers, features a carefully optimized blade count and pitch to maximize airflow (2786.5 CFM) while minimizing turbulence-induced noise. This material choice not only reduces rotating mass, lowering inertial stress on the motor, but also offers superior resistance to many chemicals, moisture, and UV exposure, making it suitable for both indoor and semi-outdoor installations. The housing and endcaps are precision die-cast from aluminum alloy, providing excellent heat dissipation for the motor and maintaining dimensional stability under thermal cycling. At the heart of the unit is the BLDCDC102 brushless DC motor, a 102 mm rotor design that eliminates the need for carbon brushes, thereby reducing maintenance and electromagnetic interference. The motor's electronic commutation is managed by an integrated controller that accepts a 24 VDC input (operating range 16–28 VDC), allowing for straightforward speed adjustment via PWM or variable DC voltage, though the standard unit runs at a fixed 1050 RPM. Electrical ratings specify a nominal current of 7.0 A and power consumption of 168 W, translating to an efficiency that undercuts many AC induction fans of similar output. The motor incorporates thermal overload protection and is insulated to Class B or higher, safeguarding against overheating in stalled or high-ambient conditions. Mechanical reliability is enhanced by dual ball bearings in the rotor assembly, rated for a lifespan exceeding 50,000 hours at 40°C operational temperature. The electrical interface consists of a 20 AWG lead wire of 500 mm length, pre-stripped and tinned for secure termination, ensuring compatibility with standard low-voltage DC distribution systems. For acoustic performance, the fan achieves a sound pressure level of 61.2 dB(A) at 1 meter, a figure that allows deployment in noise-sensitive zones like hospitals, laboratories, and open-plan offices. The unit is manufactured under ISO 9001 quality management protocols and complies with CE and RoHS directives, with optional UL recognition on request for North American integration. All components, from the zinc-plated fasteners to the corrosion-resistant aluminum, are selected to withstand harsh industrial atmospheres. FANOVA's commitment to quality is evident in the balanced impeller assembly, dynamically tested to reduce vibration and prolong bearing life. This axial fan is not merely a component but a complete ventilation solution, offering OEM/ODM customers a customizable platform for specific airflow, voltage, and connector requirements. Whether used in telecom shelters, agricultural ventilation, or clean energy equipment, the FG3G450-48PL-2L delivers consistent performance with minimal energy waste. Its low-voltage operation inherently reduces arc-fault risks and permits integration with battery backup systems, making it a future-proof choice for evolving energy landscapes. With rigorous testing for salt spray, humidity, and temperature extremes, this fan stands ready for deployment across diverse climates and applications.

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.
