FFU manufacturers have sheet metal processing capabilities. What role does it play in the project?
Direct answer: Sheet metal capabilities affect the size adaptation of the FFU box, air flow channels, filter sealing, installation and maintenance methods, and also affect the prototype adjustment and batch structure consistency of non-standard projects. When judging the manufacturer's capabilities, you should look at whether the sheet metal structure, together with the fan, motor, filter and control system, can meet the project conditions, not just the appearance of the box.
The FFU cabinet is not a simple shell. It determines how fans and filters are installed, how air moves through the equipment, and how electrical components and maintenance space are arranged. It can also be seen from the product information that the flow guide structure and filter sealing interface of the FFU are directly related to the uniformity of the air outlet and the installation method of the filter.FFU structure and installation information
Standard project: making installation and batch delivery more stable
The ceiling of the clean room has a fixed module and must avoid beams, lamps, sprinklers and inspection openings. The manufacturer can process the box itself, so that the overall dimensions, fixed positions, wiring ports and filter replacement directions can be included in the drawings. During series production, it is also easier to check the consistency of dimensions, fit and sealing around the same structural scheme.
However, consistent sheet metal dimensions do not mean consistent performance of the entire machine. It is still necessary to check the air volume, static pressure and air outlet uniformity under the same filter and operating gear.
Non-standard projects: Structural adjustment should follow performance
Equipment-side FFU, SMT equipment or projects with limited space may require lower cabinet height, different air inlet positions or special installation interfaces. Sheet metal self-processing helps to quickly adjust the structure, but after adjusting the box, the airflow path and fan operating point may also change. Therefore, non-standard designs should re-check the air volume, filter resistance and maintenance space, and pass prototype verification.
'Can make non-standard sizes' and 'the whole non-standard machine can meet the standard under specified working conditions' are two different requirements. The purchaser should request the structural drawing and complete machine test data at the same time.
Filter sealing and maintenance details are most worth checking
cabinet andThe combination location of the HEPA/ULPA filter should meet the sealing and testing requirements agreed upon by the project. Whether the filter is replaced from above the ceiling or from the indoor side will also affect the sheet metal frame, fixing method and on-site inspection space. If the sheet metal design only considers installation and not replacement, subsequent maintenance may require additional disassembly and assembly.
The advantage of Aili Industry lies in the synergy of the whole machine
Aili Industrial's motors, fans, control systems, sheet metal and filters are all produced and developed in-house. When adjusting the sheet metal structure, the installation and air supply performance of the self-developed fan and motor, the size and sealing of the filter, and the wiring and maintenance conditions of the control components can be checked simultaneously. This kind of whole industry chain support is suitable for batch configuration of standard ceilings and also for non-standard matching on the equipment side.
When evaluating manufacturers, they should be asked to explain their structure and performance confirmation methods from drawings and prototypes to batch delivery. Ai Li industrialThe FFU product solution should ultimately be verified under the filter, target air volume and resistance conditions agreed upon in the project; the specific configuration is subject to the technical agreement and test results.
When purchasing, you can directly ask: After the box structure is changed, how will the filter seal, air outlet uniformity and target air volume be retested? This question can better demonstrate the engineering value of sheet metal capabilities than asking 'can the specified size be processed' alone.
