FS3G097-24PL-50 Single Inlet Centrifugal Blower, 24VDC, 97mm, 150 m3/h

The FS3G097-24PL-50 is a single inlet centrifugal blower engineered for whisper-quiet operation, generating a mere 62 dB(A) — quieter than a normal conversation — making it ideal for noise-sensitive medical, laboratory, and office environments. Powered by a 24VDC brushless DC motor (BLDCDC53), this blower operates across a wide 16–28V input range, ensuring flexibility for solar, battery, and off-grid power systems. Despite consuming only 38.4W, it delivers an impressive maximum airflow of 88.28 CFM (150 m³/h) and a static pressure of 1.6 in.wg (400 Pa), capable of overcoming duct resistance and filter loads. The galvanized steel impeller (97mm diameter) provides industrial-grade durability, resisting corrosion and wear for long service life, while the die-cast aluminum housing adds structural rigidity and effective heat dissipation. With a rated speed of 2500 RPM and a current draw of just 1.6A, this blower offers exceptional energy efficiency — a key advantage for power-constrained installations. The motor features integrated speed control interfaces, allowing precise regulation of airflow to match varying demand, and is protected with thermal and over-current safeguards. Equipped with a 20AWG cable (143mm length), the FS3G097-24PL-50 is ready for plug-and-play integration into HVAC, ventilation, and new energy systems. Certified to meet international standards, this FANOVA blower combines quiet operation, low power consumption, and rugged construction, making it a versatile choice for equipment manufacturers and system integrators.

The FS3G097-24PL-50 is a precision-engineered single inlet centrifugal blower from FANOVA, designed to deliver high static pressure and airflow in a compact 97mm impeller package. The impeller is fabricated from galvanized steel sheet, with a blade geometry optimized for aerodynamic efficiency and reduced turbulence, ensuring stable performance across the entire operating curve. The housing and endcaps are die-cast aluminum, providing excellent dimensional stability, impact resistance, and thermal conductivity, which aids in motor cooling and prolongs component lifespan. At the heart of the blower is the BLDCDC53 brushless DC motor, a sensorless electronically commutated design that eliminates brush wear and minimizes electromagnetic interference. The motor operates on 24VDC (16–28V range), drawing a maximum of 1.6A and consuming 38.4W at the rated speed of 2500 RPM, producing a maximum airflow of 88.28 CFM (150 m³/h) and a maximum static pressure of 1.6 in.wg (400 Pa). This combination of low power consumption and high pressure generation makes the blower exceptionally suited for applications with tight energy budgets, such as solar-powered ventilation or battery-operated medical devices. Speed control is achieved via PWM or analog voltage input, enabling users to modulate airflow from 0 to 100% with smooth, linear response; the integrated driver supports both open-collector and external potentiometer interfaces for flexible system integration. The motor is protected against over-voltage, under-voltage, over-current, and over-temperature conditions, with automatic restart after fault recovery, ensuring reliable operation in demanding environments. The rotor diameter is 53mm, and the rotor assembly is dynamically balanced to minimize vibration and noise, achieving an acoustic rating of just 62 dB(A) at full speed — a level that is suitable for hospital wards, clean rooms, and office HVAC units. Bearings are high-quality ball bearings with a rated life of 50,000 hours at 40°C ambient, providing maintenance-free operation for years. The electrical interface consists of a 20AWG, 143mm lead wire with tinned ends, compliant with UL and CE requirements, and the entire unit is rated for protection against dust and moisture according to IP44 standards. All materials are RoHS-compliant, and the blower is assembled and tested under ISO 9001-certified processes, with each unit undergoing a 100% run-in test to verify performance and noise levels. The FS3G097-24PL-50 is ideal for OEM equipment manufacturers seeking a reliable, quiet, and energy-efficient centrifugal blower for HVAC, air purifiers, fuel cell ventilation, and industrial cooling applications, backed by FANOVA's commitment to quality and customization.

DC Single Inlet Centrifugal Blower
Type	FS3G097-24PL-50
Model	BLDCDC53

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 FS3G097-24PL-50 delivers 150 m3/h at 400 Pa while drawing only 38.4W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 97mm 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 97mm footprint, 0-10VDC/PWM speed control, FG tach output and standard cable make the fan simple to wire, control and service.
