FW3G215-48GL-90 Axial Fan, 48VDC, 215mm, 1846.9 m3/h

The FW3G215-48GL-90 is a high-efficiency axial fan engineered to deliver exceptional airflow in a compact 215 mm footprint, making it the perfect solution for space-constrained ventilation and thermal management systems. With a maximum airflow of 1846.9 m³/h and a power consumption of just 90 W, this fan achieves a remarkable airflow-per-watt ratio, enabling you to replace multiple smaller fans with a single, energy-saving unit. Operating on a 48 VDC input (36–57 V range), it aligns perfectly with telecommunications -48 VDC power standards, simplifying integration into DCIM-monitored networks and battery-backup installations. The brushless DC motor, designated BLDCDC92, provides long service life and quiet operation at 3200 RPM, with a noise level of 72 dB(A) that suits industrial environments where continuous airflow is critical. Its cold-rolled steel impeller offers superior durability and wear resistance, while the die-cast aluminum housing ensures robust structural integrity in demanding applications. This fan is protected against overcurrent, overvoltage, and reverse polarity, and includes thermal protection and IP55-rated ingress protection for reliable performance in dusty or humid conditions. The 20AWG cable with 500 mm length simplifies wiring, and the unit is certified to CE and RoHS standards, ensuring global compliance for OEM and ODM deployments. Ideal for telecom cabinets, renewable energy inverters, and industrial ventilation, the FW3G215-48GL-90 delivers big airflow with minimal energy draw, making it a sustainable choice for modern system designers.

The FW3G215-48GL-90 is a precision-engineered axial fan that maximizes airflow density through a 215 mm impeller fabricated from cold-rolled steel, a material chosen for its high tensile strength and resistance to mechanical wear and corrosion in industrial settings. The impeller, with its aerodynamically optimized blade geometry, generates a maximum free-air flow of 1086.9 CFM (1846.9 m³/h) at a rated speed of 3200 RPM, while maintaining a low power envelope of 90 W at 1.9 A from a 48 VDC supply (operating range 36–57 V). This low power consumption makes the fan exceptionally suitable for battery-powered or solar-fed systems where every watt counts, and its compatibility with standard telecom -48 VDC rails enables direct integration into central office equipment, base stations, and edge computing racks without the need for additional power converters. The BLDCDC92 motor employs a sensorless brushless DC drive with a high-grade ferrite rotor (92 mm diameter) and precision-balanced rotating assembly, ensuring vibration levels below 2.5 mm/s and a service life exceeding 70,000 hours under nominal conditions (L10 bearing life, at 40°C ambient). Speed control is implemented via a standard PWM input (frequency 1–10 kHz) and a 0–10 V analog signal, allowing fine-tuned modulation of airflow to match real-time thermal loads, thereby reducing average energy consumption in variable-duty cycles. The fan incorporates comprehensive electronic protections including reverse polarity, overcurrent, overvoltage, and locked-rotor auto-restart, plus a built-in tachometer output (open-collector, 2 pulses per revolution) for real-time speed monitoring by a system controller. The die-cast aluminum endcaps and housing provide excellent thermal conductivity and EMI shielding, while the insulating class is Class F (155°C) for the motor winding, enabling operation in ambient temperatures up to 70°C without derating. Mechanical construction includes a sealed ball-bearing system with high-temperature grease, designed for axial and radial loads, and the housing mounts with standard 215 mm flange holes (M4). The electrical interface is a 20AWG, 500 mm lead cable with tinned ends, rated for 300 V and 105°C, and is strain-relieved against vibration. The fan is rated IP55, protecting against dust ingress and water jets, making it suitable for outdoor telecom enclosures, agricultural ventilation, and workshop exhaust where moisture and particulate exposure are common. Quality assurance follows ISO 9001:2015 processes, and the fan carries CE (LVD/EMC) and RoHS certifications, ensuring compliance with EU directives. With its combination of high airflow, ultra-low power, and robust steel construction, this model is engineered for long-term reliability in mission-critical applications, and FANOVA's OEM/ODM service offers custom connectors, harnesses, and speed-control profiles to meet specific project requirements.

DC Axial Fan
Type	FW3G215-48GL-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 FW3G215-48GL-90 delivers 1846.9 m3/h at 440 Pa while drawing only 90W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 215mm 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 215mm footprint, 0-10VDC/PWM speed control, FG tach output and standard cable make the fan simple to wire, control and service.
