What is EFU (Equipment Fan Filter Unit)？

The EFU, or Equipment Fan Filter Unit, is a device specifically designed for air filtration and ventilation in equipment applications, particularly in cleanrooms. EFUs are used to maintain the cleanliness and particle-free environment required for sensitive equipment found in industries such as semiconductor manufacturing, biotechnology, pharmaceuticals, and other technology-driven fields.

EFUs are typically installed on or near the equipment itself, rather than on the cleanroom ceiling like traditional FFUs (Fan Filter Units). They are designed to be compact, easily attached to the equipment, and provide localized air filtration and circulation.

The EFU consists of a fan and a filter section. The fan helps to create airflow, which draws in ambient air from the surrounding environment and passes it through the filter section. The filter section is responsible for removing particles, pollutants, and contaminants from the incoming air, ensuring that only clean, filtered air is delivered to the equipment.

The filters used in EFUs are high-efficiency filters, such as HEPA (High-Efficiency Particulate Air) or ULPA (Ultra-Low Penetration Air) filters. These filters are capable of capturing particles as small as 0.3 micrometers with high efficiency, ensuring the desired level of cleanliness is maintained.

EFUs are also equipped with control systems that allow for variable airflow and fan speed adjustments, enabling precise control of air quality and flow rates to meet the specific requirements of the equipment being served.

Overall, the EFU plays a crucial role in maintaining the cleanliness and performance of sensitive equipment in cleanroom environments, ensuring the production of high-quality products and minimizing the risk of contamination.
