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

Looking for a single fan that can replace multiple smaller units while keeping noise levels lower than a normal conversation? The FANOVA FG3G450-48PL-2L axial fan delivers a massive 4735 m³/h airflow at just 61.2 dB(A), making it the perfect choice for large-volume ventilation in commercial buildings, agricultural facilities, and industrial workshops. Operating on a safe 24 VDC supply (16–28 V range), this fan is ideal for solar-powered, off-grid, and new-energy applications where low-voltage safety and energy efficiency are paramount. The 450 mm impeller, crafted from glass-fiber-reinforced polypropylene, ensures exceptional durability and chemical resistance while keeping weight low—a boon for easy installation and reduced structural load. Powered by a brushless DC motor (BLDCDC102) with a rotor diameter of 102 mm, this model achieves 1050 RPM and delivers a maximum static pressure of 137 Pa, sufficient for moderate ductwork and filter resistance. The fan includes a 20 AWG cable (500 mm) and is built with a die-cast aluminum endcap for robust housing protection. Control is flexible via PWM or 0–10 V analog signals, allowing precise speed adjustment to match real-time demand, which further enhances energy savings. With a design life exceeding 70,000 hours and compliance with CE and RoHS standards, the FG3G450-48PL-2L is a reliable and eco-friendly solution for OEMs seeking high-performance axial fans. Whether you need to ventilate a greenhouse, cool an electrical cabinet, or support battery storage systems, this FANOVA axial fan offers the perfect blend of power, silence, and safety.

The FANOVA FG3G450-48PL-2L axial fan is engineered for high-capacity, low-noise ventilation in demanding environments where space and energy efficiency are critical. The 450 mm impeller is injection-molded from polypropylene reinforced with 30% glass fiber, providing excellent mechanical strength, thermal stability up to 80°C, and superior resistance to chemicals and moisture—a combination that ensures long service life even in corrosive atmospheres. The impeller features 9 aerodynamically optimized blades with a swept design that maximizes airflow (2786.5 CFM / 4735 m³/h) while minimizing turbulence and acoustic noise. At a rated speed of 1050 RPM, the fan produces a sound pressure level of only 61.2 dB(A), making it suitable for noise-sensitive areas such as medical device enclosures, laboratory ventilation, and office HVAC systems. The motor is a brushless DC unit (BLDCDC102) with a 102 mm rotor diameter, utilizing a sensorless design that eliminates wear-prone Hall sensors and reduces maintenance. The motor delivers 168 W of power at 24 VDC (input range 16–28 V), drawing a maximum current of 7.0 A, and achieves an efficiency of over 85%, translating to lower power consumption and reduced heat generation. Speed control is implemented via two standard interfaces: a 0–10 V analog input (impedance 10 kΩ) and a PWM input (frequency 1–10 kHz, duty cycle 10–100%), both of which provide linear speed adjustment from 20% to 100% of rated RPM. For safety, the motor includes locked-rotor protection, reverse-polarity protection, and soft-start functionality to prevent inrush current spikes. The endcap and housing are precision die-cast from aluminum alloy, offering excellent thermal conductivity to dissipate motor heat and protection against impact. The fan is rated IP44 for the motor and housing, with optional IP55 upgrade available for outdoor or wash-down environments. Bearings are dual ball-type, rated for a life of 70,000 hours at 40°C ambient temperature, ensuring reliable operation in continuous-duty cycles. The electrical interface consists of a 20 AWG, 500 mm long cable with stripped and tinned leads, clearly labeled for positive, negative, tachometer (open-collector output), and control signals. The fan is compliant with CE, UL, and RoHS directives, and each unit undergoes 100% run-in testing to verify performance and vibration levels. With its combination of large impeller, low voltage, and quiet operation, the FG3G450-48PL-2L is an ideal choice for OEMs integrating high-airflow axial fans into solar power systems, electric vehicle charging stations, and industrial cooling units.

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.
