FS3G108-1AGL-70 Single Inlet Centrifugal Blower, 115VAC, 108mm, 281.8 m3/h

The FS3G108-1AGL-70 is a single inlet centrifugal blower engineered for applications where acoustic comfort and energy efficiency are paramount. Operating at just 64 dB(A), this blower runs quieter than a normal conversation, making it ideal for medical devices, laboratory equipment, and office ventilation systems. Powered by a highly efficient BLDC EC motor, it consumes only 50 W while delivering a maximum airflow of 281.8 m³/h and a static pressure of 390 Pa, ensuring reliable performance even in compact installations. This model is designed for direct connection to 115 VAC power supplies (92–138 V range), eliminating the need for external transformers in North American and Japanese markets. The galvanized steel impeller provides excellent durability and corrosion resistance, while the die-cast aluminum housing ensures robust mechanical integrity. With a 20AWG cable (159 mm) and integrated speed control, the FS3G108-1AGL-70 offers flexible installation and precise airflow management. It is certified to CE and RoHS standards and is built for long service life with high-quality bearings. Choose the FS3G108-1AGL-70 for a whisper-quiet, low-power blower that fits seamlessly into space-constrained, noise-sensitive equipment. FANOVA's OEM/ODM capabilities allow for customizations to meet your exact performance and interface requirements.

The FS3G108-1AGL-70 is a compact single inlet centrifugal blower that combines low noise emission, high efficiency, and robust construction for demanding HVAC and industrial applications. Its impeller is fabricated from galvanized steel sheet, a material chosen for its excellent resistance to corrosion, wear, and moderate heat, ensuring long-term reliability in harsh environments. The impeller has a diameter of 108 mm and is dynamically balanced to minimize vibration and acoustic noise, contributing to the blower's quiet 64 dB(A) noise level at full speed. The housing and endcap are made of die-cast aluminum alloy, providing a lightweight yet rigid frame that protects the internal components and facilitates heat dissipation. The blower is driven by a brushless DC (BLDC) motor with an electronically commutated (EC) design, operating at a nominal voltage of 115 VAC with a wide input range of 92 to 138 VAC, making it directly compatible with standard North American and Japanese power grids without the need for a step-down transformer. The motor delivers 50 W of power at a rated speed of 2800 RPM, achieving a maximum airflow of 281.8 m³/h and a maximum static pressure of 390 Pa, which is sufficient for short to medium duct runs and moderate filtration loads. The motor is equipped with a built-in control interface that allows for speed modulation via PWM or 0-10V analog signals, enabling precise airflow adjustments for variable-demand applications. Electrically, the blower draws a maximum current of 1.0 A and is protected against overcurrent and thermal overload, with motor insulation Class B. The rotor diameter is 72 mm, and the unit is fitted with high-quality ball bearings that are rated for a service life exceeding 50,000 hours at 40°C ambient temperature, reducing maintenance needs. The electrical connection is provided by a 20 AWG cable with a length of 159 mm, terminated to match standard connectors for quick and secure wiring. The FS3G108-1AGL-70 is designed to operate in a temperature range from -10°C to +60°C and is suitable for installations where space is at a premium. It meets CE and RoHS requirements, and FANOVA performs 100% final testing to ensure performance consistency. For OEM projects, the blower can be customized with alternative cable lengths, connector types, and speed control interfaces. With its ultra-low power consumption and quiet operation, the FS3G108-1AGL-70 is an excellent choice for medical equipment, analytical instruments, energy-efficient ventilation systems, and telecommunications enclosures where noise and energy use are critical factors.

AC Single Inlet Centrifugal Blower
Type	FS3G108-1AGL-70
Model	BLDCEC72

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 FS3G108-1AGL-70 delivers 281.8 m3/h at 390 Pa while drawing only 50W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 108mm 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 108mm footprint, 0-10VDC/PWM speed control, FG tach output and standard cable make the fan simple to wire, control and service.
