FFU (Fan Filter Unit) is a device used to provide a highly clean environment, often used in semiconductor manufacturing, biopharmaceuticals, hospitals and food processing where a strictly clean environment is required.
The use of FFU
FFU is widely used in a variety of environments requiring high cleanliness. The most common use is in semiconductor manufacturing, where tiny dust particles can have an impact on subtle circuits. In the biotechnology and pharmaceutical industries, FFU is often used in the manufacturing process to prevent microorganisms and other contaminants from affecting the product. In hospital operating rooms, FFUs are used to provide a clean air environment to reduce the risk of infection. In addition, FFU is also used in food processing and precision instrument manufacturing.
The principle of FFU
The working principle of the FFU is relatively simple, and it mainly works through the internal fan and filter. First, the fan draws air from the environment into the device. The air then passes through one or more layers of filters that trap and remove dust particles from the air. Finally, the filtered air is released back into the environment.
The equipment is capable of continuous operation to maintain the stability of a clean environment. In most applications, the FFU is set to continuous operation to ensure that the cleanliness of the environment is always maintained at the desired level.
Structure and classification of FFU
FFU is mainly composed of four parts: enclosure, fan, filter and control system. The housing is usually made of aluminum alloy or other lightweight materials for easy installation and maintenance. The fan is the power source of the FFU and is responsible for the intake and expulsion of air. The filter is the core part of the FFU and is responsible for removing dust particles from the air. The control system is used to adjust the speed and filtration efficiency of the fan to adapt to different environmental requirements.
Ffus can be divided into several types according to filtration efficiency and application environment. For example, the HEPA (High Efficiency Particulate Air) FFU is suitable for environments where particulate filtration above 0.3 microns is required. Ultra Low Penetration Air (ULPA) FFU is suitable for environments requiring particle filtration above 0.1 micron.
