Description

The ebm-papst R1G225-AF11-21 is a high-efficiency EC centrifugal fan engineered for precision air handling in industrial and commercial applications. Utilizing the advanced M1G074-BF GreenTech EC motor, this unit delivers a substantial airflow of 1130 m³/h while maintaining a compact footprint, making it ideal for integration into restricted spaces within air purification units and server cooling modules. The backward-curved impeller geometry is optimized to sustain high pressure, effectively overcoming system impedance caused by dense filtration media. This component features Original Engineering standards, ensuring robust performance with a wide voltage input range and integrated motor protection against reverse polarity and locked rotors. The maintenance-free ball bearing system ensures longevity even under continuous operation. We verify Technical Compatibility for seamless retrofitting and prioritize optimized Lead Time to minimize system downtime.

Industrial Application:
This specific EC fan is critical for high-performance Air Purification Systems requiring variable speed control and high static pressure. The 48V DC architecture allows for direct integration into telecom cooling cabinets and battery-backup ventilation systems where mains power may be unreliable or DC bus architecture is standard. Its high-pressure curve specifically addresses the pressure drop inherent in multi-stage HEPA and activated carbon filtration stacks, ensuring consistent air exchange rates without thermal overload.

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.
