Air Handling Units (AHU)

As the core power component of the air handling unit (AHU), the EBST DC backward centrifugal fan drives the mixing, heat exchange and delivery of fresh and return air. Through efficient air flow organization, it ensures the unit stably outputs clean and constant-temperature air under different loads. It is widely used in large central air conditioning systems such as commercial buildings, hotels and hospitals.

Fan Filter Units (FFU)

Suitable for scenarios with extremely high air cleanliness requirements such as clean rooms, laboratories and electronic workshops, the EBST DC backward centrifugal fan provides stable and low-disturbance clean air flow for FFUs. Combined with high-efficiency filters, it effectively intercepts micron-level particles, ensuring the dust-free environment and product quality in workshops/laboratories.

Internet date center

Aiming at the high-density heat dissipation demand of small data center (IDC) cabinets, this fan quickly dissipates a large amount of heat generated by the operation of core equipment such as servers and switches in the cabinet through efficient centrifugal pressure output. It maintains the equipment in the optimal working temperature range, avoids performance degradation or failure caused by overheating, and ensures the continuity of data transmission and storage.

High-Voltage Inverter Cabinets

The IGBT modules, inverters and other components in the high-voltage inverter cabinet release a lot of heat during operation. The EBST DC backward centrifugal fan forces the air circulation in the cabinet with precise air volume and pressure, quickly dissipates the heat and keeps the temperature in the cabinet uniform. It prevents components from aging and breakdown due to high temperature, ensuring the stable operation and long service life of the inverter system.

Q5：What precautions should be taken when installing the DC backward centrifugal fan?

A5: There are 3 core precautions for installation: ① The installation position must be flat and firm to avoid vibration during fan operation, which affects the service life; ② The air duct connection must be tightly sealed to prevent air leakage, and the weight of the air duct should not directly act on the fan casing; ③ Sufficient maintenance space should be reserved during installation for subsequent maintenance, and ensure that the air inlet and outlet of the fan are not blocked to ensure smooth air flow.

Q6：What work should be done for the daily maintenance of the DC backward centrifugal fan?

A6: The key points of daily maintenance are 3 points: ① Regularly clean the dust and debris on the fan impeller and casing to avoid dust accumulation affecting air volume and operation efficiency; ② Regularly check the motor operation status, check for abnormal noise, overheating, etc., and troubleshoot in time; ③ After long-term shutdown, first check whether the fan components are intact, and put them into use after normal trial operation to avoid faults caused by component aging.
