FW3G200-48GS-90 Axial Fan, 48VDC, 200mm, 1205 m3/h

This 48V DC axial fan delivers whisper-quiet operation at just 62 dB(A), making it ideal for noise-sensitive environments like medical labs and office ventilation systems where ambient sound levels must stay below conversational volume. The FW3G200-48GS-90 from FANOVA combines ultra-efficient brushless DC motor technology with a rugged galvanized steel impeller, ensuring both long service life and dependable performance in demanding industrial settings. Operating on a 48VDC input (36–57V range) with a low power draw of only 60 watts, this fan excels in telecom and new energy applications where energy conservation and battery compatibility are critical. It generates a maximum airflow of 1205 m³/h (709.14 CFM) and a static pressure of 250 Pa (1.0 in.Wg), sufficient for moderate duct resistance and filter loads. The die-cast aluminum housing and galvanized steel blades provide corrosion resistance and mechanical strength, while the 20AWG cable simplifies wiring in control cabinets. With a speed of 3000 RPM and a current draw of just 1.25 A, this fan offers precise, low-current operation for DCIM-integrated cooling systems. It features inherent protection against overcurrent and overvoltage, plus Class B insulation for reliable startup in varying conditions. Designed for 50,000-hour bearing life, the FW3G200-48GS-90 is a cost-effective, maintenance-free solution for telecom racks, solar inverters, and cleanroom filtration units. Certified to CE and RoHS standards, this axial fan is a trusted choice for OEMs seeking a quiet, energy-efficient airflow component.

The FW3G200-48GS-90 is a purpose-engineered axial fan that prioritizes acoustic comfort and electrical efficiency without compromising on industrial durability. At the heart of this unit is a 200mm galvanized steel impeller with a 92mm rotor diameter, constructed from high-strength sheet steel that resists corrosion, abrasion, and thermal stress, making it suitable for continuous operation in dusty or humid environments. The impeller's aerodynamic blade profile, optimized for low turbulence, contributes to the fan's 62 dB(A) noise rating—a figure that falls below typical office conversation levels (60–65 dB) and is a key differentiator for medical, laboratory, and HVAC applications where noise regulations are stringent. The motor is a BLDCDC92 brushless DC type, electronically commutated for high efficiency and minimal electromagnetic interference. It operates on a 48VDC nominal supply with a broad input range of 36 to 57VDC, accommodating fluctuations common in telecom -48V plants and renewable energy storage systems. At 3000 RPM, the fan delivers a maximum airflow of 1205 m³/h and a static pressure of 250 Pa, which is adequate for pushing air through HEPA pre-filters or extended duct runs in cabinet cooling. Power consumption is a modest 60W, with a full-load current of 1.25A, enabling direct connection to battery-backed DC buses without the need for AC conversion. Speed control is achieved via PWM (pulse-width modulation) or voltage trimming, allowing the system integrator to modulate airflow based on thermal load, thereby further reducing energy use and acoustic output during partial-load operation. The motor incorporates built-in protection against reverse polarity, overcurrent, and locked-rotor conditions, while the winding insulation is Class B (130°C), ensuring safe operation under elevated ambient temperatures. The endcaps and housing are precision die-cast aluminum, which not only dissipates heat effectively but also provides a stable mounting interface with standard 200mm fan guards. Bearings are high-grade ball bearings rated for 50,000 hours at 40°C ambient, delivering a maintenance-free lifespan suitable for 5–7 years of continuous service. Electrical connection is via a 20AWG lead cable, color-coded for positive, negative, and tachometer output, which provides a speed signal for monitoring in DCIM (Data Center Infrastructure Management) systems. The fan is balanced to ISO 1940 G2.5 grade, ensuring vibration-free operation that protects downstream sensitive equipment. Production is ISO9001 certified, and the product meets CE and RoHS directives, making it compliant for export to EU and North American markets. For OEMs in telecom, solar inverter, 5G base station, and electric vehicle charging sectors, this fan offers a compact, low-power, high-reliability cooling solution that aligns with green energy mandates and carbon reduction goals. Forcier on long service life and quiet operation, the FW3G200-48GS-90 is a drop-in upgrade for legacy AC fans in retrofit projects, providing immediate energy savings of up to 50% while simplifying control interfaces.

DC Axial Fan
Type	FW3G200-48GS-90

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
