Sheet metal processing
Whole machine assembly
Product testing
Finished product area
Quality control, starting from core components
A truly stable product does not just rely on final inspection, but controls every key link starting from the manufacturing of core components. Aili Industrial incorporates motors, fans, control systems and filters into its own quality management system, and continuously controls product performance and consistency through component testing and complete machine testing.
Motor performance testing
Test the motor's operating performance, electrical parameters and operating status to ensure that the power system meets the long-term operation requirements of FFU.
Fan performance testing
Test the operating status, air volume and related performance of the centrifugal fan to provide stable aerodynamic performance for the entire equipment.
Control system function test
Test the control board, speed control function, communication function and control logic to ensure that the FFU can respond stably to different control instructions.
Filter performance testing
Conduct relevant performance testing of HEPA and ULPA filters according to product requirements to ensure that the filters meet design and application requirements.
Overall machine comprehensive performance test
After completing the assembly of core components, the FFU will be tested for complete machine operation and comprehensive performance to confirm that the coordinated operation of each system is normal.
From parts to finished products, how is each step inspected?
Through whole-process quality control, we can reduce the performance fluctuations of the entire machine caused by differences in the performance of parts and components, and ensure that purification equipment such as EFU has stable operating performance and good batch consistency.
When the motor, fan, control system, filter and complete machine are all controlled by its own manufacturing system, when performance deviations occur in the product, the problem can be quickly located and optimized, rather than relying on repeated coordination with multiple external suppliers.
Aili Industrial has verified product performance at all levels through full-process quality management and multiple performance tests. We are not only concerned about whether the EFU can operate normally, but also whether it can operate stably for a long time in a clean environment.
From manufacturing capabilities to customer value
Independent research and development, full industry chain manufacturing and engineering customization capabilities are not only different production methods, but also directly affect the performance, customization, quality and project delivery of EFU.
01｜Performance is more controllable— starting from core components to master FFU performance
Core links such as motors, fans, control systems and filters are manufactured independently, allowing each component to be matched around the needs of the entire machine and reducing performance differences between different suppliers.
Motor｜Fan｜Filter｜Control system
02｜Customization is more flexible - not restricted by standard products
Aili Industry can adjust the structure, power, filtration and control to provide customized solutions for special applications.
Size | Structure | Air volume | Wind speed | Filtration | Control
03｜More stable quality - from parts to complete machine, layer-by-layer control
Aili Industrial combines core component testing, production process control and complete machine performance testing, not only focusing on the final product, but also controlling the performance and consistency of the EFU from the source.
Component inspection｜Process control｜Complete machine testing
04｜More reliable delivery - complete manufacturing system supports project delivery
The 30,000-square-meter modern production base covers core component manufacturing, sheet metal, filters and FFU complete machine assembly, providing stable production and delivery support for standard products and mass customization projects.
Independent production | Mass manufacturing | Stable delivery
Only when core capabilities are in your own hands can you truly achieve controllable performance, flexible solutions, stable quality, and reliable delivery.
This is also the basis for Aili Industries to continue to provide solutions from standard high-efficiency air supply outlets to customization for special applications.
