Direct answer: When evaluating FFU manufacturers, attention should be paid to the R&D and manufacturing capabilities of fans and motors, control systems, sheet metal boxes, HEPA/ULPA filters, and complete machine testing. At the same time, check non-standard responses, batch configuration consistency, and delivery packages. The key is not how many parts the manufacturer can provide, but whether these parts can match the agreed working conditions of the project.
FFU is used for local air supply in clean rooms, clean sheds and equipment. Projects vary in size, air volume, filtration efficiency and control requirements. chooseWhen FFU is a manufacturer , it can check its capabilities along the path of 'component design, complete machine assembly, working condition testing, and batch delivery'.
The fan and motor should be matched according to the target air volume, filter resistance, operating gear and power consumption requirements. The maximum air volume in the product information cannot directly represent the design air volume of the FFU after installing the filter. The project also needs to see the performance data corresponding to the target air volume under the specified filter and operating gear.
For projects that operate continuously or require speed adjustment, the air volume, power consumption, noise and electrical conditions of commonly used gears should also be checked. After the fan or motor configuration is changed, the operating point of the entire machine should be re-confirmed.
Batch FFU projects may require single unit speed regulation, regional control, centralized monitoring and different working modes. The manufacturer should be able to explain the controller capacity, communication interface, address planning, status feedback and capacity expansion methods, and verify the correspondence between the control gear and the actual air supply volume.
Aili Industrial's self-developed control system can configure the control scheme based on the number of project units, process partitions and operating modes. When centralized management is required, you can learn more aboutFFU group control system . The control scheme should be verified at the prototype stage, rather than judging suitability based solely on a feature list.
The box determines whether the FFU can be installed in the ceiling or equipment interface, and is also related to the air inlet position, air flow channel, filter sealing and maintenance direction. For standard clean rooms, the ceiling modulus should be checked; for semiconductor equipment, SMT equipment or projects with limited space, the height, openings or wiring positions may need to be adjusted.
After the sheet metal structure is adjusted, the air supply path may change accordingly. Therefore, the non-standard cabinet should be confirmed simultaneously with the fan, filter and complete machine testing, and the selection cannot be completed based on the structure diagram alone.
HEPA/ULPA air filters should be selected based on cleanliness goals and particle control requirements, and the resistance, testing requirements and replacement methods under the design air volume should be noted. When increasing the filtration level, it is necessary to recheck the fan operating point and the overall air volume.
The sealing of the filter and box is equally important. The test data of the filter itself, post-installation sealing inspection and on-site cleanliness verification should be implemented into the project requirements respectively.
Production capabilities should ultimately be reflected in testing and delivery documents under agreed working conditions. Projects can focus on checking:
stage |
What should be confirmed |
|---|---|
prototype |
Size, filter configuration, performance at target air volume, control and maintenance conditions |
mass production |
Consistency requirements for component and complete machine configuration, testing methods, and key performance |
On-site installation |
Actual air volume, air flow distribution, sealing and cleaning effect |
Clean room performance testing methods should be developed according to the project airflow type and operating status; ISO 14644-3 provides a framework of relevant test methods. Specific test items, allowable deviations and judgment methods should be written into the technical agreement.
Aili Industrial's motors, fans, control systems, sheet metal and filters are all produced and developed in-house. For standard clean rooms, the entire machine can be configured around the ceiling module, target air volume, and control zones; for equipment or non-standard projects, the structure, air supply, filtration, and control conditions can be adjusted simultaneously, and the matching results can be confirmed through the prototype.
This ability to cover key components to the entire machine helps project parties discuss specifications, quantities, testing and delivery around the same technical requirements. Specific product configuration and performance should be subject to the project technical agreement and actual working condition test data.
Question: Can the FFU manufacturer produce a single component and complete the whole machine customization?
Answer: It is also necessary to check the matching and test results of the fan, motor, filter, box and control system under the project conditions.
Q: How to compare different FFU solutions for batch projects?
Answer: First unify the filter, operating gear, target air volume and test conditions, and then compare the overall machine performance, configuration and delivery scope.
