Description

The ebmpapst R3G400-AD23-24 is a high-performance backward-curved centrifugal fan engineered for precision air handling in critical industrial environments. Utilizing GreenTech EC (Electronically Commutated) motor technology, this 400 mm unit delivers superior aerodynamic performance with significantly reduced power consumption compared to traditional AC equivalents. Designed specifically for 48 VDC systems, it is an ideal solution for telecom infrastructure, data center cooling, and Fan Filter Units (FFU) requiring precise airflow modulation. The unit features a robust sheet aluminum impeller directly integrated onto the external rotor motor, ensuring compact dimensions and dynamic balancing. Its integrated electronics provide intelligent control via 0-10V or PWM interfaces, allowing for demand-based operation that extends service life and minimizes acoustic noise.

Industrial Application:
This specific 48 VDC configuration is critical for telecommunications base stations and uninterruptible power supply (UPS) ventilation systems where direct DC bus integration is required to bypass rectification losses. It is also extensively used in cleanroom Fan Filter Units (FFU) where precise speed control is necessary to maintain constant laminar flow despite increasing filter resistance over time. The unit ensures thermal stability in high-density electronic cabinets without introducing electromagnetic interference.

Fans Maintenance and upkeep

1. The use environment should always be kept clean and tidy, the surface of the fan should be kept clean, there should be no sundries in the inlet and outlet air outlets, and the dust and other sundries in the fan and pipes should be cleaned regularly;

2. The fan can only operate under the condition that it is completely normal, and at the same time, it is necessary to ensure that the capacity of the power supply facilities is sufficient and the voltage is stable.

3. During the operation of the fan, if it is found that the fan has abnormal sound, the motor is seriously heated, the shell is live, the switch trips, and cannot be started, it should be stopped immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the fan, and a test run should be carried out for about five minutes after the overhaul to confirm that there is no abnormal phenomenon before starting the operation;

4. The fan should be stored in a dry environment to avoid moisture on the motor. When the fan is stored in the open air, there should be defensive measures. In the process of storage and handling, the fan should be prevented from bumping to avoid damage to the fan.
