A FFU (Fan Filter Unit) is a combination of a fan and a filter, also known as a "filtering device with an integrated fan." When used in cleanrooms, FFUs are typically installed at the air supply end of the cleanroom and are commonly placed on a sealed grid frame system. The FFU is divided into two parts: the upper part contains the fan module, while the lower part houses the high-efficiency filter. Depending on the cleanliness requirements of the cleanroom, the filter can be a high-efficiency (HEPA) or ultra-high efficiency (ULPA) filter, ensuring a supply of clean air to the cleanroom environment.
In addition to overcoming the resistance of the lower high-efficiency filter, the FFU system also needs to overcome the resistance from all components within the airflow path in order to maintain the set operating air velocity. The FFU system offers several advantages, including easy design and construction, flexible air velocity adjustment, and easy modification of the clean zone. Due to these features, FFUs are extensively used in industrial cleanrooms. Experience the benefits of FFU systems in your cleanroom environment to achieve efficient and reliable air filtration.

A FFU (Fan Filter Unit) operates by drawing air (wind) into the internal fan, which then passes the absorbed air (wind) through the HEPA or ULPA filter located underneath the FFU. This filter effectively removes larger particles and dust particles from the air. Finally, the clean air is uniformly supplied to the cleanroom at a wind speed of 0.45m/s ± 10%.
The basic structure of a cleanroom involves the air first passing through the MAU (Make-Up Air Unit), which is equipped with a pre-filter filter. The clean air then enters the top of the cleanroom and proceeds to be further filtered by the FFU, which acts as a secondary filter with a HEPA or ULPA filter. The filtered air is then distributed throughout the cleanroom space. The air that has descended is collected by the raised floor and returns to the air handling unit through the return air plenum, completing the circulation.
By employing the FFU system, cleanroom environments can maintain high levels of air cleanliness, essential for various industries such as electronics manufacturing, pharmaceuticals, and biotechnology. The FFU plays a crucial role in ensuring the delivery of clean air and helping to maintain a controlled and sterile environment.

A Fan Filter Unit (FFU) works by using a combination of a fan and a filter to control and clean the air in a specific area, typically a cleanroom or controlled environment. The main components and working principle of a FFU are as follows：
1. Fan: The FFU contains an internal fan, usually a centrifugal fan, that is responsible for drawing in the surrounding air and creating airflow within the unit. The fan can be dynamically balanced to ensure smooth operation and minimize noise generation.
2. Air Filter: The FFU is equipped with a high-efficiency particulate air (HEPA) or ultra-low particulate air (ULPA) filter. These filters are designed to capture and remove small particles, such as dust, pollen, bacteria, and airborne contaminants, from the incoming air. HEPA filters typically remove particles as small as 0.3 micrometers with an efficiency of 99.99%, while ULPA filters can remove particles as small as 0.12 micrometers with efficiencies up to 99.9999%.
3. Airflow Control: The fan draws air into the FFU, and it passes through the HEPA or ULPA filter, where particles are trapped and retained. The clean, filtered air is then discharged uniformly and evenly from the FFU, creating a laminar airflow pattern. This controlled airflow helps to maintain the desired cleanliness level within the environment.
4. Uniform Distribution: FFUs are designed to supply air at a consistent and uniform velocity. The airflow velocity is typically set at 0.45 m/s (or specified as per requirements) to ensure adequate particle suspension and distribution within the controlled environment. The FFUs are strategically placed in the cleanroom ceiling or walls to achieve optimal airflow coverage.
5. Pressure Control: Some FFUs are equipped with a pressure control system that monitors and maintains the pressure differential between the cleanroom and the surrounding area. This helps prevent contamination from entering the cleanroom by ensuring that air flows from controlled areas to uncontrolled areas.
Overall, the main function of a FFU is to provide a controlled, clean, and sterile airflow within a specific environment. They are widely used in industries like semiconductor manufacturing, pharmaceuticals, biotechnology, and other cleanroom applications where maintaining a clean and particle-free environment is critical.
