Brief Description
The FS3G133-48GL-70 is a DC single-inlet centrifugal fan with a compact design, suitable for applications with limited installation space. Operating at 48VDC, it delivers an airflow of 220 m³/h and a static pressure of 310 Pa, supports flexible speed control and signal feedback, and is ideal for built-in ventilation and cooling in various small to medium-sized equipment.
Product Specification
The FS3G133-48GL-70 is a DC single-inlet centrifugal fan equipped with a BLDC72 external rotor brushless motor, rated for 48VDC operation with an input range of 36–57VDC. It provides a maximum airflow of 220 m³/h and a maximum static pressure of 310 Pa, operating at 2000±5% RPM with a power consumption of 58W and a sound pressure level of 64 dB(A), balancing ventilation performance with energy efficiency and noise control. Featuring a single-inlet design, it delivers airflow directly from the outlet, making it suitable for directional ventilation applications. The electrical system offers a dielectric withstand voltage of 600VAC and integrates multiple protections including soft start, over/under voltage detection, locked-rotor protection, and thermal overload protection, with an operating temperature range of -25℃ to 60℃ for reliable performance in diverse environments. Its mechanical construction uses a galvanized steel sheet impeller and a die-cast aluminum end cover, with a 133mm diameter impeller featuring 38 blades to enhance airflow efficiency, a total weight of approximately 3600g (including inlet), supports installation in any orientation, and carries an IP44 protection rating. Control interfaces support both 0–10VDC analog and PWM (1–10kHz) digital speed adjustment, along with an FG tachometer output (2 pulses per revolution). The product is certified to CE, RoHS, ISO9001, and ErP standards, and is well-suited for electronics cabinet cooling, small instrument ventilation, telecommunications equipment cooling, and other applications requiring a compact structure and moderate static pressure.

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.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
Ⅴ.The fan needs to be operated and used under the guidance of professional personnel to prevent children from coming into touch this product
Ⅵ.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
Ⅶ.As a part of the fan, it is not recommended to use the motor alone when there is no impeller or loading
