FW3G250-12GS-90 Axial Fan, 12VDC, 250mm, 1921.5 m3/h

The FW3G250-12GS-90 is a 12 VDC axial fan engineered to deliver industrial-grade airflow without the power penalty, pushing up to 1921.5 m³/h at free air while consuming only 98.4 W—a performance-per-watt ratio that makes it the clear choice for replacing multiple smaller fans in space-constrained equipment. Its 250 mm impeller, forged from cold-rolled steel plate, provides the structural rigidity needed for continuous operation in demanding environments, from HVAC air handlers to battery energy storage systems. This model achieves a maximum static pressure of 295 Pa, enabling it to overcome moderate duct resistance and filtration media, while the brushless DC motor ensures whisper-quiet operation at just 70 dB(A). Built on a 12 VDC platform with a 9 V to 13.2 V operating range, it draws 8.2 A at peak load and can be speed-controlled via PWM or voltage tuning, offering flexible integration with existing control systems. The die-cast aluminum endcaps and housing not only dissipate heat effectively but also withstand corrosion and mechanical shock, extending service life even in semi-outdoor or washdown-prone installations. With dual-ball bearings rated for 50,000 hours at 60°C, this fan is built for long-term reliability in telecom cabinets, medical equipment, and renewable energy inverters. Certified to CE and RoHS, the FW3G250-12GS-90 from FANOVA combines steel-blade durability with low-voltage safety, making it a top-tier OEM choice for engineers prioritizing efficiency and lifespan.

The FW3G250-12GS-90 is a high-performance axial fan from FANOVA, designed for original equipment manufacturers requiring a robust, energy-efficient cooling solution at 12 VDC. The impeller is fabricated from cold-rolled steel plate, a material chosen for its high tensile strength and resistance to deformation under centrifugal load, ensuring stable airflow even after years of continuous duty. The blade profile is aerodynamically optimized to maximize volumetric flow, achieving 1130.8 CFM (1921.5 m³/h) at free air, while the shrouded design minimizes tip loss and noise. The motor is a brushless DC (BLDC) type, model BLDCDC92, with an internal electronic commutation circuit that eliminates brush wear and reduces electromagnetic interference. Rated at 98.4 W and 8.2 A, the motor operates across a 9 V to 13.2 V input window, with speed control achieved through PWM signal input or variable DC voltage, allowing precise thermal management in closed-loop systems. The fan delivers a maximum static pressure of 295 Pa (1.18 in.wg), sufficient for pushing air through HEPA pre-filters, heat sinks, or ductwork with moderate bends. The rotor diameter is 92 mm, and the entire rotating assembly is balanced to ISO 1940 G2.5 grade, reducing vibration and bearing stress. Dual ball bearings are employed, rated for 50,000 hours of life at 60°C ambient, and the bearing system is sealed to prevent lubricant leakage. The endcaps and housing are die-cast aluminum alloy, providing excellent thermal conductivity and structural integrity, while the surface is treated with a corrosion-resistant coating for humidity resistance. Electrical connection is via a 20 AWG lead wire, with polarity protection and reverse voltage protection built into the drive circuit. The fan is protected against overcurrent, overvoltage, and locked-rotor conditions, and the insulation class is B, with dielectric strength tested at 500 VAC for one minute. The unit complies with CE and RoHS directives, and is manufactured under ISO 9001 quality management systems. This axial fan is suitable for applications in HVAC systems, battery cooling, telecom shelters, medical devices, and industrial ventilation, where its combination of high airflow, low power draw, and steel impeller durability offers a compelling advantage over plastic-blade alternatives.

Type	FW3G250-12GS-90
Model	BLDCDC92

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 FW3G250-12GS-90 delivers 1921.5 m3/h at 295 Pa while drawing only 98.4W, 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.
