Internal Structure of FFU

The internal structure of an FFU consists of several key components that work together to achieve efficient air filtration and circulation. At its core, the unit includes a fan, a filter, and a housing structure. These elements are designed to optimize airflow while minimizing resistance, ensuring that clean air is effectively distributed throughout the environment.

The FFU's internal structure can be broken down into the following key components:

• Fan:The fan is responsible for drawing in ambient air and pushing it through the filter. Typically, it is a high-efficiency, low-noise fan designed to provide a constant airflow.

• Filter:The filter, which can be a HEPA or ULPA type, captures particles and contaminants from the air, ensuring that the air released back into the environment meets the required cleanliness standards. According to iso 14644-1, HEPA filters can achieve an efficiency of 99.97% for particles as small as 0.3 microns.

• Housing:The housing encloses the fan and filter, providing structural integrity and supporting easy installation. It is often made from materials such as galvanized steel or aluminum, which are resistant to corrosion and easy to clean.

• Control System:Many FFUs are equipped with control systems that allow for monitoring and adjusting airflow rates, ensuring optimal performance based on real-time conditions.

The combination of these components ensures that FFUs can effectively maintain cleanroom conditions, as demonstrated in Deiiang’s cleanroom solutions.

Working Principle of FFU

The working principle of an FFU revolves around the process of air filtration and circulation. The unit draws in ambient air through its intake, passing it through a high-efficiency filter. The fan then pushes the filtered air back into the cleanroom environment. This continuous cycle ensures that the air remains clean and free from contaminants, which is crucial for sensitive applications.

The FFU operates based on the following steps:

• Air Intake:Ambient air is drawn into the FFU through the intake grille. This air may contain various particulates and contaminants that need to be filtered out.

• Filtration:The air passes through a HEPA or ULPA filter, which effectively captures particles, bacteria, and other pollutants present in the air. HEPA filters can remove 99.97% of particles that are 0.3 microns in size, ensuring high air quality.

• Air Circulation:After filtration, the fan within the FFU pushes the clean, filtered air back into the cleanroom or controlled environment. This process helps maintain a constant airflow, which is essential for preventing the accumulation of contaminants.

• Pressure Maintenance:The FFU also aids in maintaining a slight positive pressure in the cleanroom, which is crucial for preventing outside air infiltration and ensuring that contaminants are kept at bay.

• Monitoring Control:Many modern FFUs are equipped with monitoring systems that can provide real-time data on airflow rates, filter status, and overall performance. This allows for proactive maintenance and ensures compliance with cleanliness standards.

Companies like Deiiang utilize advanced FFU technologies that enhance performance and reliability, ensuring that their cleanrooms remain compliant with ISO standards.

In summary, the FFU’s working principle is grounded in its ability to filter and circulate air efficiently. The integration of the fan and filter creates a system that continuously purifies the air in controlled environments. The effective filtration process ensures that contaminants are removed, while the circulation of clean air helps maintain the necessary cleanliness levels required for sensitive operations. Additionally, the ability to monitor airflow and filter performance allows for timely maintenance and operational efficiency.
