FW3G250-24PD-72 Axial Fan, 24VDC, 250mm, 1571 m3/h

Unleash the power of sustainable ventilation with the FANOVA FW3G250-24PD-72, a 24VDC axial fan engineered to deliver exceptional airflow of up to 1571 m3/h (924.5 CFM) while consuming only 66W, making it a single-fan solution that replaces multiple lower-capacity units. This model operates at a whisper-quiet 46 dB(A), quieter than a typical conversation, ensuring a serene environment for medical, laboratory, and office settings where noise is a critical factor. The fan features a glass-fiber reinforced polypropylene impeller (250mm diameter) that combines lightweight durability with excellent chemical resistance, ideal for demanding applications. Powered by a high-efficiency BLDC EC motor with a broad 16-28V DC input range, it integrates seamlessly with solar, new energy, and off-grid power systems, prioritizing low-voltage safety. With a maximum static pressure of 190 Pa, it effectively handles long ducting and moderate resistance filters. The die-cast aluminum housing ensures robust mechanical integrity, while precision ball bearings guarantee a long operational lifespan. This model includes comprehensive protection features such as reverse polarity and locked-rotor safeguards, and is fully compliant with CE and RoHS standards. Choose the FW3G250-24PD-72 for a compact, energy-efficient, and remarkably silent axial fan solution. Trust FANOVA, a leading OEM/ODM manufacturer, to deliver performance and reliability for your critical ventilation needs.

The FW3G250-24PD-72 is a high-performance axial fan from FANOVA, designed for applications requiring a perfect balance of high volume airflow, energy efficiency, and low acoustic signature. At the heart of this unit is a 250 mm diameter impeller crafted from glass-fiber reinforced polypropylene (PP+GF), offering a superior strength-to-weight ratio, inherent resistance to a wide range of chemicals and moisture, and excellent dimensional stability even under continuous operation. The impeller's aerodynamically optimized blade profile achieves a maximum airflow of 1571 m³/h (924.5 CFM) and a maximum static pressure of 190 Pa, enabling effective air movement through ductwork, filters, and heat exchangers with minimal pressure drop. Propulsion is provided by an advanced BLDC (Brushless DC) electronically commutated motor, which operates on a 24V DC supply with a wide input voltage range of 16V to 28V DC, making it highly tolerant of voltage fluctuations common in renewable energy systems. The motor draws a maximum current of 2.76A and 66W of power, delivering a peak efficiency of over 80%, significantly reducing energy consumption and heat generation compared to traditional AC fans. Speed control is achieved via a 0-10V DC or PWM (pulse width modulation) interface, allowing for precise, continuous speed adjustment from idle to its maximum 2500 RPM, enabling the fan to be tuned to the exact thermal or ventilation requirements of the system. The motor is equipped with electronic protections including reverse polarity, over-current, and locked-rotor protection, ensuring fail-safe operation in harsh electrical environments. The entire motor assembly is sealed with an insulation class of Class B (130°C) and a protection rating of IP42, safeguarding against vertical water drips and solid particles larger than 1mm, suitable for indoor and protected outdoor installations. The fan's housing is constructed from die-cast aluminum alloy (ADC12), providing a rigid, corrosion-resistant frame that effectively dissipates heat and dampens vibration. Long operational life is assured by dual precision ball bearings, rated for 50,000 hours of operation at 40°C ambient temperature, ensuring reliability in continuous-duty applications such as telecom cabinets, EV charging stations, and HVAC systems. Electrical connection is made via standard 20AWG lead wires, color-coded for easy integration (Red=V+, Black=V-, Blue=Control Signal), and the fan is certified to CE, RoHS, and REACH standards. With its rugged construction, versatile control options, and exceptional efficiency, the FW3G250-24PD-72 is the preferred choice for OEMs seeking a reliable, high-performance axial fan for next-generation equipment.

DC Axial Fan
Type	FW3G250-24PD-72
Model	BLDCEC72

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 FW3G250-24PD-72 delivers 1571 m3/h at 190 Pa while drawing only 66W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 250mm 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 250mm footprint, 0-10VDC/PWM speed control, FG tach output and standard cable make the fan simple to wire, control and service.
