How does the FFU manufacturer's self-developed control system help project customization?

Direct answer: The self-developed control system helps FFU manufacturers adjust the overall machine solution based on the number of projects, control partitions, operating modes and communication requirements, and verify whether speed regulation, status feedback and actual air volume are consistent during the prototype stage. For batch or non-standard projects, whether the control system can be synchronized with fans, motors, filters and cabinets is more important than adding a separate control function.

Clean room projects often require dozens or even more FFUs to operate by area; equipment-side projects may require FFUs to start and stop with the production equipment, use designated interfaces, or be installed in a limited space. If the control plan is determined separately from the overall machine design, it is easy to have a situation where the speed adjustment command has been issued but the actual air supply does not meet the process requirements.

Project customization, the first thing to customize is the running logic

Different areas may require different working and duty speeds, and may also require single unit adjustment, zone control or centralized monitoring. The manufacturer's self-developed control system can implement these requirements into control partitions, address planning, communication interfaces, status feedback and expansion plans during model selection.

For example, when a clean room is expanded and a new FFU is added, it is not just about adding a control address. It is also necessary to confirm whether the motor control methods of the new and old equipment are compatible, whether the original controller has capacity margin, and whether the new air supply will change the original air flow balance. Projects that require centralized management can be planned simultaneously during the design phaseFFU group control system。

The control gear should correspond to the real air supply performance

The control system displays 'high speed' or 'low speed', which does not directly prove that the work area has obtained the required air volume. For each operating gear to be used, the air volume, static pressure and wind speed uniformity under project resistance conditions should be checked after the FFU is equipped with the specified filter.

When the filter resistance changes, the air volume at the fixed gear may change; if the project requires maintaining the target air supply, the control strategy must also be checked together with the fan capacity and maintenance conditions. Therefore, control system customization should be based on complete machine test data, not just on interface functions.

What are the advantages of Aili Industrial’s self-research?

Aili Industrial's motors, fans,The control system , sheet metal and filters are all produced and developed in-house. When the project proposes special communication interfaces, operating modes or installation structures, the control plan can be combined with the fan motor performance, box wiring and maintenance space,HEPA/ULPA filter resistance is matched simultaneously.

This whole industry chain collaboration is suitable for batch partition management of standard clean rooms, as well as for non-standard semiconductor equipment, SMT equipment and space-limited projects.FFU configuration . The value of customization should ultimately be verified by the prototype: whether the control instructions can be executed correctly, whether status and fault information can be fed back as agreed, and whether the actual air supply in each mode meets the project goals.

Before batch delivery, it is recommended to specify the number of FFU, partition and address rules, communication interface, working mode, expansion requirements and test methods in the technical agreement. The specific control functions and overall machine performance are subject to the project technical agreement and actual working condition test results.

To judge whether the control system is truly suitable for a customized project, you can ask: 'After adding or changing an operating mode, can the manufacturer simultaneously provide the complete air volume data and control verification results of the corresponding gear?' This can better explain whether the system and FFU match the control interface than just looking at the control interface.
