What information do I need to provide for non-standard EFU customization? Size, performance and interface list
Direct answer: Non-standard EFU usually matches directly with the customer's equipment structure. In order to avoid 'the size can be installed but the performance is not enough' or 'the performance is satisfactory but cannot be repaired', the customization data must also include mechanical, electrical, air flow, filtration and acceptance information. It is recommended to use the same version of the confirmation diagram and parameter table as the technical benchmark for both parties.
Mechanical and spatial information
Provide equipment assembly or related area drawings, marking the available length, width and height, installation reference plane, hole positions, flanges or buckles, peripheral interference parts, structural load-bearing and allowable protrusion range. If the drawings need to be kept confidential, an interface diagram with irrelevant information removed can be provided.
air performance data
Describe the target total air volume, average wind speed, working static pressure, wind speed uniformity, operating gear and allowable noise. If the static pressure cannot be directly given, the air inlet grille, air outlet structure, filter and internal air flow path of the equipment should be described for program evaluation.
Filtration and cleaning requirements
Clarify H13, H14, U15 or other efficiency levels, rated air volume, filter size, sealing method, leak detection or particle detection requirements, and replacement directions. Don't just write 'high efficiency filtering', otherwise the acceptance boundary will not be clear.
Electrical and communication interfaces
Confirm the voltage, frequency, terminal blocks, cable length, speed control method, RS485 and other communication requirements, device address, status feedback and fault handling logic. When linking with the main device, the control rights and status after power outage should also be clarified.
Materials, Surface Treatment and Maintenance
Explain the box material, surface treatment, anti-static requirements, cleaning restrictions, maintenance directions of fans and filters, available tool space and replacement methods of wearing parts.
Prototype and acceptance data
Agree on the number of prototypes, test conditions, measurement methods, measurement points, instrument requirements and data recording formats. The drawings, parts list and program version after confirmation of the prototype should be solidified as the basis for mass production.

FAQ
Can I quote only the overall dimensions of the equipment?
A preliminary assessment can be made, but an accurate plan will also require air volume, filtration, interfaces and maintenance requirements.
Do all components have to be changed for non-standard EFU?
uncertain. Mature fan, motor, control and filter platforms can be reused first, and only necessary structures can be adjusted.
How to reduce post-production changes?
Complete a joint review of mechanical, electrical, airflow and maintenance aspects before placing an order, and clarify the acceptance conditions.
How does Aili Industry cooperate with equipment-side EFU projects?
Aili Industry carries out R&D and production around EFU complete machines, fans and motors, control systems, sheet metal structures and air filters. For equipment-side projects, configuration can be carried out based on equipment drawings, target air volume, static pressure, filtration efficiency, installation interface and control logic. When it comes to ultra-thin, small size or special interfaces, it is recommended to confirm the drawings and agreed working conditions first, and then test the curing parameters through the prototype so that the configuration can be consistent in subsequent mass production.
During project consultation, the available internal length, width and height of the equipment, target cleanliness, air supply area, air volume or wind speed requirements, filtration efficiency, power supply and communication methods can be provided to facilitate quick judgment of whether standard products are suitable or whether non-standard design is required.

Conclusion: Non-standard EFU customized data should cover equipment space, air supply area, air volume and static pressure, filtration efficiency, power supply control, installation, maintenance and acceptance methods. The more complete the data, the easier it is to detect interference and performance risks during the prototype phase.
