How does the FFU project divide the configuration requirements of key areas and auxiliary areas?
Partitioning is the prerequisite for configuration differences
In an FFU project, different areas may have different requirements for cleanliness, airflow and operational stability. Critical areas typically have direct contact with product exposure or high-risk processes, while auxiliary areas may be aisles, buffer zones, equipment maintenance areas, or low-risk operating areas.
If the entire project is dimensioned according to the same configuration, the critical areas may be insufficient and the auxiliary areas may be excessive. If the configuration is differentiated by region, it is necessary to clarify which areas are critical areas and which are auxiliary areas, and how to verify and manage the configuration differences in different areas.
Therefore, partitioning is the prerequisite for FFU configuration differences. If the partitioning is unclear, there is no basis for configuration differences. Aili Industrial has complete production capabilities in terms of FFU complete machines and project supporting equipment, and can provide different configuration solutions according to project zoning requirements.

How to identify key areas
Critical areas usually have several characteristics. The product is exposed directly to the air without packaging or protection. The process is sensitive to particles or microorganisms, and contamination can lead to defective products. There is frequent movement of people and materials, and the risk of contamination is high. The process equipment itself may generate particles or chemical gases. The project has clear requirements for cleanliness levels or airflow.
The location and scope of the critical area should be determined based on the process flow diagram, equipment layout and personnel movement lines. The critical area is not necessarily the entire room, it may be certain workstations, above certain equipment or certain operating areas.
Once critical areas are identified, their cleanliness levels, airflow patterns, target wind speeds or air changes, and the types of pollutants that need to be controlled should be recorded.
How to identify the auxiliary area
Auxiliary areas usually include personnel passages, material buffer areas, equipment maintenance areas, non-critical operating areas and partial return air areas. The cleanliness requirements of auxiliary areas are usually lower than those of critical areas, but a basic clean environment still needs to be maintained to avoid interference with critical areas.
The identification of auxiliary areas also requires a combination of process layout and personnel logistics. If the auxiliary area is adjacent to the critical area, the air flow direction and pressure difference need to be considered to prevent contaminated air from the auxiliary area from entering the critical area.
The configuration of the auxiliary area can be relatively simplified, but it still needs to meet basic air supply, return air and cleanliness requirements.
How to determine configuration differences
The difference in configuration between the key area and the auxiliary area can be reflected in several aspects. Filter efficiency rating, critical areas may use higher efficiency filters. With the number and arrangement of FFU, critical areas may require denser air supply coverage. Depending on the wind speed or number of air changes, critical areas may require higher air supply volumes. Control methods, critical areas may require independent control or constant air volume control. Maintenance requirements, critical areas may require more frequent inspections and tighter sealing.
Configuration differences should be determined based on regional risks and objectives rather than simply allocated by room area. For critical areas, configuration should prioritize ensuring protection effects. For auxiliary areas, the configuration can consider economy while meeting basic requirements.
How to manage boundaries
The boundary between critical and auxiliary areas needs to be managed. Boundaries can be partitions, soft curtains, differential pressure controls or airflow separations. If the boundary is unclear, air from the auxiliary area may enter the critical area, affecting the cleanliness of the critical area.
Boundary management should confirm the following: boundary location and form; whether the airflow direction flows from the critical area to the auxiliary area or vice versa; whether the pressure difference is maintained; whether personnel need to be buffered or changed when entering and exiting; whether materials need to be cleaned or replaced when entering and exiting.
For areas with strict requirements, boundaries may need to be confirmed through verification. Boundary verification includes differential pressure measurement, airflow direction observation and cleanliness testing.
How to verify configuration differences
The configuration differences between the critical area and the auxiliary area need to be verified during the installation, commissioning and operation stages. The verification content includes: wind speed, cleanliness and air flow direction in the critical area; air supply and cleanliness in the auxiliary area; air flow direction and pressure difference at the boundary; the impact of personnel operations and material entry and exit on the critical area.
If verification finds that critical areas are not up to standard, configuration or operational management may need to be adjusted. If the auxiliary zone is overprovisioned, consider optimization to reduce operating costs.
Issues that should be confirmed in advance during project communication
During the FFU project zoning and configuration design stage, it is recommended to confirm the following with the designer and FFU manufacturer: process flow and location of critical areas; product exposure and contamination risks; personnel and material flow paths; cleanliness levels and airflow requirements; boundaries between critical areas and auxiliary areas; configuration differences and verification methods; control methods and maintenance requirements; whether partition debugging and verification are required.

in conclusion
FFU project zoning should be determined based on product exposure, process risks, personnel logistics, and regional airflow connections. Critical areas and auxiliary areas can have different requirements, but configuration differences must be able to be verified and managed. Boundary management and partition verification are important links to ensure that configuration differences are valid.
