FD3G180-24GL-20 Dual Inlet Centrifugal Blower, 24VDC, 180mm, 1651.7 m3/h

The FD3G180-24GL-20 is engineered to move massive volumes of air on a low-voltage 24VDC platform, delivering a peak airflow of 1651.7 m3/h to replace multiple smaller fans in space-constrained equipment. This dual inlet centrifugal blower achieves that high flow while keeping acoustic output at just 65 dB(A), below typical conversational speech, making it suitable for noise-sensitive environments. At its rated 1200 RPM, the unit produces a maximum static pressure of 191 Pa, sufficient for moderate duct runs and filter loads in HVAC and ventilation systems. Powered by a brushless DC motor (BLDCDC102) with a 102 mm rotor, it draws 6.8 A and consumes 163.2 W, offering energy-efficient performance compared to equivalent AC blowers. The 24VDC input (16-28V range) enables safe operation in low-voltage applications, including solar-powered and off-grid installations. Constructed with a cold-rolled steel impeller and die-cast aluminum housing, this blower provides industrial-grade durability against wear and corrosion. The included 20AWG, 500mm cable simplifies wiring, while the motor supports variable speed control for precise airflow adjustment. Certified for international markets, the FD3G180-24GL-20 suits applications ranging from commercial HVAC units to battery cooling and cleanroom air handling. FANOVA backs this model with robust quality assurance, ensuring long service life in demanding continuous-duty operations.

The FD3G180-24GL-20 is a dual inlet centrifugal blower designed for high-volume, low-voltage airflow applications, featuring a 180 mm diameter impeller fabricated from cold-rolled steel plate for superior mechanical strength and resistance to deformation under high-speed rotation. The impeller's blade geometry is optimized for dual-sided air intake, maximizing volumetric efficiency while maintaining a compact footprint suitable for integration into skids, enclosures, and rooftop units. The housing and endcaps are precision die-cast from aluminum alloy, offering excellent dimensional stability, heat dissipation, and corrosion resistance even in humid or mildly aggressive atmospheres. At the core is the BLDCDC102 brushless DC motor, which employs a 102 mm rotor and electronic commutation to eliminate brush wear, reduce electromagnetic interference, and extend operational lifespan to over 50,000 hours at rated conditions. The motor operates from a 24VDC supply with a working range of 16 to 28 volts, accommodating battery voltage sag and solar panel fluctuations without performance degradation. Under nominal load, the blower draws 6.8 A and consumes 163.2 W, translating to a high airflow-to-power ratio that supports energy-conscious system designs. Maximum airflow is rated at 1651.7 m3/h (972.03 CFM) at free-air conditions, while maximum static pressure reaches 191 Pa (0.76 in.wg), enabling effective air movement through short duct sections or moderately loaded filters. Speed control is implemented via PWM or 0-10V analog input, allowing the host controller to modulate airflow from 0 to 1200 RPM with smooth, linear response. The motor is protected against overcurrent, overvoltage, and locked-rotor conditions, and the insulation system meets Class B standards, making the blower suitable for ambient temperatures up to 60°C. Vibration is minimized through balanced impeller assembly and precision bearings, which are sealed and lubricated for life, ensuring quiet operation with noise levels capped at 65 dB(A) at the rated speed. Electrical interconnection is provided via a 20AWG lead wire harness of 500 mm length, color-coded for positive, negative, and control signals, and the cable is strain-relieved at the housing to prevent pull-out damage. The blower conforms to CE and RoHS directives, and FANOVA's manufacturing process includes 100% run-in testing to verify airflow, current, and noise parameters before shipment. For OEMs requiring a reliable, low-voltage blower that can replace multiple smaller fans while simplifying power distribution, the FD3G180-24GL-20 offers a durable, high-performance solution backed by rigorous quality control and global certification.

DC Dual Inlet Centrifugal Blower
Type	FD3G180-24GL-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 FD3G180-24GL-20 delivers 1651.7 m3/h at 191 Pa while drawing only 163.2W, 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.
