FS3G180-24GL-20 Single Inlet Centrifugal Blower, 24VDC, 180mm, 1254 m3/h

The FS3G180-24GL-20 is a high-pressure single inlet centrifugal blower engineered for demanding 24VDC applications where low-voltage safety meets industrial-grade performance. This model delivers a maximum airflow of 737.98 CFM (1254 m3/h) and a peak static pressure of 2.85 in.wg (712 Pa), making it ideal for long duct runs, high-resistance filters, and multi-outlet distribution systems. Powered by a brushless DC motor (BLDCDC102), it consumes 324 W at 1800 RPM and operates on a wide 16–28V input range, ensuring stable operation in solar, new energy, and off-grid environments. The galvanized steel impeller (180 mm diameter) provides superior corrosion resistance and mechanical durability, while the die-cast aluminum endcaps add rigidity and heat dissipation. Equipped with a 20AWG cable (262 mm), the fan offers simple integration into battery or renewable energy systems, with low-voltage safety eliminating shock hazards. Advanced electronic protection includes overcurrent, overvoltage, and thermal cutoff, complemented by high-temperature insulation and long-life bearings rated for continuous heavy-duty service. Noise output is a moderate 76 dB(A), acceptable for industrial settings such as HVAC booster stations, cleanroom pre-filters, and agricultural ventilation. The FS3G180-24GL-20 meets CE and RoHS standards, positioning it as a reliable choice for OEMs needing a powerful yet safe blower. FANOVA's engineering ensures this unit replaces multiple smaller fans, reducing system complexity and energy losses.

The FS3G180-24GL-20 represents a convergence of high static pressure capability and low-voltage DC architecture, tailored for modern renewable-energy and industrial ventilation systems. At its core lies a brushless DC motor (BLDCDC102) with a rotor diameter of 102 mm, electronically commutated for high efficiency and long service life. The motor operates on 24VDC nominal (accepting 16–28V input) and draws a maximum current of 13.5 A, delivering 324 W of shaft power at a rated speed of 1800 RPM. This configuration generates a maximum airflow of 737.98 CFM (1254 m3/h) and a maximum static pressure of 712 Pa (2.85 in.wg), enabling the blower to overcome resistance from HEPA filters, long ducts, or multiple branch outlets without sacrificing volumetric delivery. The impeller is fabricated from galvanized steel sheet, with a diameter of 180 mm, providing excellent resistance to corrosion, moisture, and abrasive particles common in industrial air streams. The blade geometry is optimized for backward-curved performance, reducing turbulence and improving aerodynamic efficiency across the operating envelope. The housing and endcaps are precision die-cast from aluminum alloy, offering high strength-to-weight ratio and enhanced thermal conductivity to dissipate motor heat effectively. Speed control is implemented via a 0–10V analog or PWM interface, allowing seamless integration with building management systems or custom controllers; the motor driver supports closed-loop speed regulation to maintain consistent airflow despite voltage fluctuations. Electrical protection includes overcurrent limiting, reverse polarity protection, and undervoltage lockout, while the insulation system is rated Class B, suitable for ambient temperatures up to 60°C. The fan employs dual ball bearings with a design life exceeding 50,000 hours at rated load, ensuring reliable operation in continuous-duty applications. The electrical interface is a 262 mm cable with 20AWG conductors, terminating in bare leads or optional connectors for flexible wiring. Vibration is minimized through dynamic balancing of the impeller assembly, keeping noise to 76 dB(A) at the maximum operating point. The unit is certified to CE and RoHS standards, with production following ISO 9001 quality management protocols. This blower is ideally suited for battery-powered equipment, solar ventilation systems, telecom shelter cooling, and industrial process air movement where 24VDC safety and high static pressure are critical.

DC Single Inlet Centrifugal Blower
Type	FS3G180-24GL-20
Model	BLDCDC102

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 FS3G180-24GL-20 delivers 1254 m3/h at 712 Pa while drawing only 324W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 180mm 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 180mm footprint, 0-10VDC/PWM speed control, FG tach output and standard cable make the fan simple to wire, control and service.
