Fan: The fan is the core component of the FFU, responsible for providing power and generating airflow. It draws in ambient air and pushes it into the filter for purification.
Filter: FFUs are typically equipped with high-efficiency air filters such as HEPA (High Efficiency Particulate Air) filters or ULPA (Ultra-Low Particulate Air) filters. These filters can effectively remove particles, bacteria, viruses, and other harmful substances from the air, providing clean air output.
Housing: The housing of an FFU is a closed structure, usually made of metal. Its purpose is to protect internal components, ensure the direction of airflow, and provide structural support.
Control System: Some advanced FFUs may be equipped with a control system for monitoring and controlling the fan's speed, operating mode, alarms, and other functions. The control system can ensure the stable operation of the FFU and provide a user-friendly operating interface.
Airflow Regulation Device: Some FFUs come with airflow regulation devices such as adjustable dampers or louvers, which can also be set through the controller. These devices can adjust the airflow direction and speed at the outlet to meet the requirements of different cleanrooms.
These components work together to provide efficient and stable clean air for cleanrooms.
The working principle of FFU (Fan Filter Unit) is to generate airflow through a fan, the air is sucked in and filtered through a high-efficiency filter, and then evenly distributed into the clean room through the outlet to provide a continuous supply of clean air for the working environment. At the same time, the independent air circulation system and adjustable airflow control function of FFU allow it to adapt to different clean requirements and application scenarios. The detailed description is as follows:
1. Start-up and airflow generation:
When the FFU is started, the internal fan begins to rotate. The fan is usually designed in a centrifugal style, generating negative pressure through rotation to suck in surrounding air. The airflow generated by the fan is the basis of FFU operation, providing the necessary power for subsequent filtering and air distribution.
2. Air filtration:
The sucked-in air passes through the filter inside the FFU. These filters are usually high-efficiency filters (HEPA) or ultra-high-efficiency filters (ULPA), capable of capturing and removing tiny particles, dust, bacteria, viruses, and other pollutants in the air. The core function of the filter is to improve air quality, ensuring that only clean air is discharged through the FFU outlet.
3. Air distribution:
The purified air passing through the filter is evenly distributed into the clean room through the outlet at the bottom of the FFU. This uniform distribution is achieved through the airflow design inside the FFU and the outlet design, ensuring that the air covers the entire working area evenly. FFUs usually have adjustable airflow control functions to adjust the air volume as needed to meet the cleanliness requirements of different working environments.
4. Independent air circulation system:
FFU has an independent air circulation system, which means it can be flexibly arranged and adjusted to adapt to different clean room layouts and requirements. The independent circulation system of FFU also means that it can be controlled separately, not affected by other equipment or systems, ensuring its stability and reliability.
5. Maintenance and replacement:
Over time, the filters will gradually become saturated and need to be replaced regularly to ensure filtering effectiveness.
When selecting FFU configurations, it is important to consider factors such as air purification level, air volume and static pressure, fan type, control method, power requirements, noise levels, maintenance, and replacement. These factors collectively impact the performance, energy efficiency, and long-term operational effectiveness of the FFU.
