Fan filter units (FFUs) are high-efficiency air filters used to provide clean and particle-free air in controlled environments such as clean rooms, laboratories, and manufacturing facilities. An FFU consists of a fan, a filter, and a housing that can be mounted on a ceiling or a wall. The fan draws in air from the room, passes it through the filter, and then discharges it out of the unit. This ensures that the air in the controlled environment is free from airborne particles that could damage delicate equipment or contaminate products.
The features of FFUs include high airflow rates, low noise levels, and low power consumption. They are designed to operate continuously, ensuring a constant supply of clean air to the controlled environment. Some FFUs come equipped with HEPA or ULPA filters that can remove particles as small as 0.3 microns, ensuring a clean environment. FFUs can be used in conjunction with other air filtration systems such as HVAC systems to provide additional filtration and improve the air quality.
FFUs are used in various applications, including clean rooms for manufacturing semiconductors, pharmaceuticals, and medical equipment. They are also used in hospitals, laboratories, and research facilities where clean air is critical. FFUs can also be used in food processing facilities, automotive manufacturing plants, and aerospace facilities. They are suitable wherever there is a need for clean air.
