FW3G200-24GS-90 Axial Fan, 24VDC, 200mm, 1205 m3/h

The FW3G200-24GS-90 axial fan redefines quiet efficiency for battery-powered and off-grid ventilation systems, delivering a remarkable 1205 m³/h airflow at just 62 dB(A)—quieter than normal conversation. This 24VDC unit, with a wide 16–28V input range, is engineered for solar, telecom, and new energy applications where low-voltage safety and energy conservation are paramount. The galvanized steel impeller, with its 200mm diameter and precision-balanced blade design, ensures exceptional durability against industrial wear, moisture, and corrosive environments. Running at 3000 RPM, the fan generates 250 Pa static pressure, making it capable of overcoming moderate duct resistance while consuming only 60W—ideal for long-duration battery operation. The sensorless brushless DC motor (BLDCDC92) offers high efficiency and a lifespan exceeding 50,000 hours, supported by dual ball bearings for reliable continuous service. Speed control via PWM or 0-10V analog input allows precise tuning to match dynamic ventilation demands, while reverse polarity and locked-rotor protection safeguard the electronics. The die-cast aluminum housing dissipates heat effectively and withstands harsh industrial conditions, meeting IP54 ingress protection for semi-outdoor use. Applications include telecom cabinets, energy storage systems, medical equipment, and cleanroom ventilation, backed by CE, RoHS, and UL certifications. FANOVA’s OEM/ODM expertise ensures this model can be customized for voltage, connectors, and performance to suit your exact specifications.

The FW3G200-24GS-90 is a 24VDC axial fan engineered for environments where acoustic comfort and low power consumption are non-negotiable. Its impeller, fabricated from galvanized steel sheet, resists corrosion, abrasion, and high temperatures, making it a robust choice for continuous industrial service. The impeller diameter of 200mm, combined with a 92mm rotor, achieves an optimal balance between airflow (709.14 CFM or 1205 m³/h) and static pressure (1.0 in.wg or 250 Pa) at a rated speed of 3000 RPM. This pressure capability supports ducted installations with moderate bends and filters, ensuring consistent ventilation without performance degradation.

The core of the fan is the BLDCDC92 sensorless brushless DC motor, which delivers up to 60W of shaft power with efficiency exceeding 80% across the operating range. The motor is electronically commutated, eliminating brush wear and reducing electromagnetic interference, while its digital control architecture enables smooth speed regulation. Users can interface via PWM (frequency 25kHz) or 0-10V analog signals, allowing seamless integration with building management systems, battery charge controllers, or custom IoT platforms. The wide voltage tolerance (16–28VDC) ensures stable operation even with fluctuating solar panel output or discharging battery banks.

Protection features include reverse polarity, overcurrent, locked-rotor detection, and soft-start, all managed by an onboard microcontroller. The motor windings are insulated to Class B (130°C), and the entire assembly is protected to IP54, guarding against dust and water splashes from any direction. Dual ball bearings, rated for 50,000 hours at 40°C ambient, provide long maintenance-free life, while the die-cast aluminum endcaps and housing enhance heat dissipation and structural rigidity—critical for mounting in vibrating equipment.

Electrical connection is via a 20AWG lead wire, 300mm long, with stripped and tinned ends (or optional connector kits), rated for 300V. The fan weighs approximately 1.8kg and operates over a temperature range of -20°C to +70°C (storage -40°C to +85°C). It meets CE, RoHS, and UL standards, and production is ISO9001-certified. FANOVA offers full customization: speed settings, cable length, connectors, and performance curves can be tailored to OEM requirements, making this model ideal for medical devices, clean benches, telecom shelters, and renewable energy inverters.

DC Axial Fan
Type	FW3G200-24GS-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 FW3G200-24GS-90 delivers 1205 m3/h at 250 Pa while drawing only 60W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 200mm 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 200mm footprint, 0-10VDC/PWM speed control, FG tach output and standard cable make the fan simple to wire, control and service.
