Coordinate the filtration, fans, structure and control configuration around the fresh air, humidity treatment and supplementary air needs of the clean room.
Aili Industrial Clean Room Fresh Air Treatment Unit (MAU) is used to filter and treat the outdoor air with temperature and humidity according to the design requirements, and then send it into the clean room air system to provide support for process exhaust and supplementary air, personnel fresh air and system air volume balance.
Compared with general fresh air equipment, clean room MAU selection requires more attention to the target air supply status, filtration division, exhaust changes, and cooperation with the circulation system. The control of supply air and exhaust air will affect the pressure difference, humidity and clean operating conditions of the clean room.
Aili Industrial can determine the functional sections, filters, fans and control plans based on the designed fresh air volume, external static pressure, outdoor air conditions, supply air temperature and humidity requirements, and cold and heat source conditions, and carry out non-standard customization based on the installation space.
→ Check the fresh air and supplementary air requirements together → The air supply status is determined according to the system requirements
→ Collaborative matching of hierarchical filtration and fans → Support the complete machine and terminal equipment matching
The clean room MAU should first clarify the fresh air volume, moisture load and air supply processing tasks it undertakes, and then determine the equipment configuration. The fresh air volume cannot be directly equated to the clean room circulating air volume.

Aili Industrial has the capabilities of motor manufacturing and independent research and development and production of fans. It can match the fan working point based on the design air volume, filter and coil resistance, external static pressure and speed regulation requirements.
For fresh air systems that need to be adjusted according to the exhaust air or operating mode, the fan adjustment range, low-load operation and control mode can be checked simultaneously to align component selection with project operation requirements.
Relying on its air filter manufacturing capabilities, Aili Industrial can jointly confirm the filtration level, rated air volume, installation size, sealing and replacement space with the overall machine structure, and check the impact of changes in filter resistance on the fan.
When it comes to the control of gaseous pollutants, chemical filtration solutions can be communicated separately. Evaluation should be based on target pollutants, concentration, temperature and humidity, and treatment air volume. Particulate matter filtering configuration cannot be used to replace gaseous pollutant control.
Aili Industrial has sheet metal processing and complete machine assembly capabilities. It can combine the size of the machine room, transportation channels, functional section layout and maintenance requirements to communicate the box segmentation, air outlet position, connection direction and maintenance side.
For multiple unit projects, the structure, interfaces and spare parts specifications can be uniformly checked to facilitate on-site installation and subsequent maintenance management.
Aili Industrial has the ability to develop control system software and hardware, and can communicate fan speed adjustment, damper linkage, temperature and humidity adjustment, filter pressure difference prompts and abnormal alarms as needed.
When it is necessary to connect to exhaust, cold and heat sources or project monitoring systems, the sensor location, control logic, signal type and communication interface can be clarified during the planning stage, and the specific functions will be implemented according to the confirmed configuration.
Aili industrial products cover MAU matching air conditioning boxes, fan boxes, FFU, EFU, HEPA/ULPA filters, chemical filters and high-efficiency air supply outlets. Fresh air treatment and terminal equipment can be checked under the same project conditions.
Relying on the R&D and manufacturing collaboration between Suzhou and Guangde, it can cooperate with solution confirmation, component production, sheet metal processing, complete machine assembly and testing, and support project customization and batch delivery.
In a system using MAU + FFU + dry coil, the following division of labor can be understood; the specific load distribution and air path should be subject to the project design.

Circulating air volume, filtration efficiency and system resistance |
Dry Coil (DCC) |

The FFU fan filter unit
combines the circulating air volume, filtration requirements and control method selection of the clean area, and checks the operation tasks with the MAU respectively.
HEPA/ULPA air filters
determine efficiency, air volume, resistance and sealing structure according to the installation location, taking into account filtration performance and maintenance requirements.
The high-efficiency air supply port
is used in the corresponding duct-type terminal filter air supply system, and the single-port air volume, interface and installation form can be confirmed simultaneously.
MAU is also an air handling equipment. Clean room projects pay more attention to the balance of supply air, the moisture content or dew point of the supply air, the division of filtration and the linkage with the circulation system. The specific differences depend on the technical requirements and configuration.
It is usually necessary to distinguish between fresh air volume and circulating air volume. The MAU undertakes the fresh air treatment tasks assigned by the design, and the circulating filtered air supply can be undertaken by the FFU or other equipment.
Humidity-related requirements need to be clarified at the same time. Especially when there is a dehumidification task, the moisture content, dew point or temperature and humidity conditions that can be used for calculation should be provided, and the cold source capacity should be checked.
The pressure difference needs to be coordinated by air supply, exhaust, leakage and control strategies. The MAU is part of the system and should be designed and commissioned together with other equipment and building conditions.
The filtration level and location are determined by the system design and need to be selected based on the back-end FFU or terminal filtration equipment, outdoor air conditions, system resistance and maintenance methods.
The air volume, filtration, structure and control requirements of the unit and FFU can be checked simultaneously according to project requirements. The specific scope of supply and interfaces are specified in the technical plan.
Provide fresh air volume, exhaust conditions, external static pressure, outdoor design conditions, target air supply status, cold and heat sources and installation dimensions to facilitate further determination of equipment configuration. If you already have FFU, dry coil or circulation system data, you can submit it for verification together.
