The FS3G180-48GL-20 is a 48 VDC single inlet centrifugal blower engineered for high-static-pressure applications in telecommunications, data centers, and industrial ventilation systems. With a maximum static pressure of 840 Pa and airflow up to 1360 m³/h, this blower delivers robust performance through long duct runs, high-resistance filters, and multi-outlet configurations. Powered by a brushless DC motor operating across a 36–57 VDC range, it draws 8.75 A at 420 W and spins at 2050 RPM, producing 78 dB(A) of noise. The galvanized steel impeller and die-cast aluminum housing ensure industrial-grade durability and corrosion resistance, while the 102 mm rotor diameter contributes to efficient, quiet operation. Built-in protection features and Class B insulation enhance reliability in demanding environments. The blower is designed for 48 VDC telecom buses, enabling direct integration with DCIM systems without additional converters. Its high power (>200 W) allows a single fan to replace multiple smaller units, reducing complexity and energy losses. Bearing life is extended for continuous duty, and the unit meets CE and RoHS certifications. Ideal for HVAC, new energy, and industrial air handling, the FS3G180-48GL-20 is a versatile solution from FANOVA, a trusted OEM/ODM manufacturer.
The FS3G180-48GL-20 is a high-performance single inlet centrifugal blower from FANOVA, designed to excel in high-static-pressure environments. The impeller, with a 180 mm diameter, is fabricated from galvanized steel sheet, offering excellent mechanical strength, corrosion resistance, and wear tolerance—ideal for industrial and semi-outdoor conditions. The housing is die-cast aluminum, providing a lightweight yet rigid structure that dissipates heat effectively. The motor is a brushless DC type (model BLDCDC102) with a rotor diameter of 102 mm, ensuring high efficiency and long service life. It operates on a 48 VDC supply (range 36–57 VDC), drawing 8.75 A and consuming up to 420 W at the rated speed of 2050 RPM. The blower delivers a maximum airflow of 1360 m³/h (800.4 CFM) and a maximum static pressure of 840 Pa (3.36 in.wg), making it suitable for overcoming duct resistance, HEPA filters, and multi-branch distribution. Speed control is achieved via PWM or 0–10 V analog input, allowing precise modulation of airflow and pressure. The motor features electronic commutation with Hall sensors, ensuring smooth startup and quiet operation at 78 dB(A). Protection includes overcurrent, overvoltage, and over-temperature safeguards, while the insulation class is B. Bearings are high-quality ball bearings rated for a lifetime of 50,000 hours at 40°C ambient. The electrical interface uses a 20 AWG cable of 262 mm length, pre-terminated for easy connection. The blower is compliant with CE and RoHS, reflecting FANOVA's commitment to quality and environmental standards. With its high static pressure, high power (>200 W), and galvanized steel construction, the FS3G180-48GL-20 is engineered for reliable, continuous operation in telecom shelters, battery rooms, industrial ovens, and clean-air applications. Its 48 VDC compatibility aligns with standard telecom power buses, enabling direct DCIM integration and reducing conversion losses.

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 FS3G180-48GL-20 delivers 1360 m3/h at 840 Pa while drawing only 420W, 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.
