FD3G146-24GL-92 Dual Inlet Centrifugal Blower, 24VDC, 146mm, 1220.6 m3/h

The FD3G146-24GL-92 dual inlet centrifugal blower redefines quiet operation for 24V DC systems, delivering a mere 63 dB(A) at full speed—quieter than a normal conversation—making it an invisible workhorse for noise-sensitive environments like medical devices, laboratory equipment, and office ventilation. This compact blower pairs whisper-level acoustics with a powerful airflow of 1220.6 m³/h and a static pressure of 544 Pa, ensuring efficient air movement through ductwork or filters without the need for multiple smaller fans. Engineered around a robust galvanized steel impeller with a 146 mm diameter, the FD3G146-24GL-92 offers industrial-grade durability and corrosion resistance, perfect for continuous-duty applications in challenging conditions. The 24 VDC motor operates across a wide 16–28 V input range, allowing flexible integration with solar power, battery backup, and off-grid new energy systems while maintaining low-voltage safety. With a power draw of only 110.4 W and a current rating of 4.6 A, this blower delivers high performance with exceptional energy efficiency, reducing operational costs over its long service life. The die-cast aluminum housing and endcaps provide structural rigidity and effective heat dissipation, ensuring reliable operation even under sustained load. Protected by standard insulation and designed for long bearing life, the FD3G146-24GL-92 is built for maintenance-free operation in OEM equipment. Certified to CE and RoHS standards, this blower is an ideal choice for HVAC, air purification, and industrial ventilation applications that demand both silence and strength. Choose FANOVA's FD3G146-24GL-92 to upgrade your system with a low-noise, high-efficiency air-moving solution that fits seamlessly into modern low-voltage power architectures.

The FD3G146-24GL-92 is a dual inlet centrifugal blower engineered for applications where acoustic comfort and low-voltage DC power converge. At the heart of this unit lies a galvanized steel sheet impeller with a 146 mm diameter and backward-curved blades, precisely balanced to minimize vibration and aerodynamic noise. The use of galvanized steel ensures excellent resistance to corrosion, moisture, and wear, making the blower suitable for industrial air handling, spray booths, and other semi-harsh environments. The impeller is driven by a brushless DC motor (BLDCDC92) with a rotor diameter of 92 mm, delivering 1350 RPM at the rated 24 VDC input. The motor's electronic commutation eliminates brush wear and reduces electromagnetic interference, contributing to the unit's remarkably low noise signature of 63 dB(A). The wide voltage range of 16–28 VDC accommodates fluctuations common in battery or solar-powered systems, while the motor control interface supports PWM speed regulation for precise airflow modulation. This enables the blower to adapt to varying demand, optimizing energy consumption and extending component lifespan. Electrically, the unit draws 4.6 A at full load, consuming 110.4 W to generate up to 1220.6 m³/h of airflow and 544 Pa of static pressure—figures that position it as a high-efficiency replacement for multiple smaller fans in space-constrained equipment. The housing and endcaps are manufactured from die-cast aluminum, offering superior thermal conductivity and mechanical strength, which aids in motor cooling and protects internal components from impact. The blower integrates a 20AWG cable of 209 mm length, providing a secure and standard electrical interface for OEM integration. For mechanical reliability, the unit employs dual ball bearings rated for long life at elevated temperatures, ensuring stable performance over thousands of operating hours. The motor is protected with automatic thermal cutoff and current limiting, preventing damage under stall or overvoltage conditions. The FD3G146-24GL-92 is designed to meet CE and RoHS directives, underscoring FANOVA's commitment to safety and environmental compliance. Its compact footprint and versatile mounting options make it a preferred choice for medical ventilators, laboratory fume hoods, telecom enclosures, and energy-efficient ventilation systems. By combining low-voltage safety, steel-impeller toughness, and ultra-quiet operation, this blower offers OEMs a reliable, future-ready air-moving platform.

DC Dual Inlet Centrifugal Blower
Type	FD3G146-24GL-92
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 FD3G146-24GL-92 delivers 1220.6 m3/h at 544 Pa while drawing only 110.4W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 146mm galvanized steel sheet impeller resists corrosion, wear and high temperatures, making the fan suitable for harsh industrial environments and corrosive gas streams.
