How to customize the special air outlet EFU? Equipment drawings, performance parameters, interfaces and prototype confirmation

How to customize the special air outlet EFU? The starting point is not to draw the shape of the air outlet first. The direction, location, size and internal flow guide structure of the air outlet will change the air flow path, air outlet uniformity and system resistance. To customize a special air outlet EFU, you must first freeze the equipment boundaries and acceptance conditions, then decide the direction, location, size, diversion structure and connection method of the air outlet, and then confirm the airflow organization and overall machine performance through prototype verification. Make the appearance first and then add the performance. After installing the prototype, you will find that the air outlet direction is biased or the wind speed is uneven, making modifications more expensive. Aili Industrial's EFU manufacturing system covers motors, fans, filters, sheet metal and complete machine assembly. The structure, airflow and complete machine performance of special air outlet EFUs can be checked according to equipment drawings in the same manufacturing system. There is no need to transfer parameters back and forth between the sheet metal factory, fan factory and complete machine factory. This is why many equipment manufacturers will refer to the structural plan description of Aili Industrial when customizing special air outlet EFUs.

Equipment drawings: The direction and position of the air outlet are frozen first

The first step in customizing a special air outlet EFU is to freeze the equipment drawings and air outlet requirements. The direction in which the air outlet faces, which side of the EFU it is on, the distance from the protected area, and whether there is any structural obstruction around it, must be confirmed before design. The direction of the air outlet does not match the air flow path inside the equipment, and the air supply cannot cover the target area; the position of the air outlet is blocked by the structure, and the effective air supply volume decreases. The drawings are not frozen, the air outlet is changed again and again, and the subsequent performance matching and prototype verification have to be reworked.

Ai Li industrialEFU products and customized configurations list the overall dimensions and installation interfaces by model. When the equipment factory freezes the direction of the air outlet, it can directly correspond to the specific model, and the air outlet requirements and the equipment general drawing are put on the same picture for verification. For the relationship between the wind direction and the protection area, please refer toWhat should we pay attention to in the direction of EFU air outlet? structural, electrical, commissioning and rectification points .Checking methods in

Performance parameters: The air volume and resistance must be re-confirmed after the air outlet is changed.

Special air outlets change airflow paths and system resistance. The direction of the air outlet changes, the airflow steering angle changes, and the internal resistance increases; the size of the air outlet decreases, the air outlet speed increases, and the resistance increases; the air outlet is added with a diversion structure, and the airflow distribution improves but the resistance may change. When customizing, check the target air volume, external static pressure, air outlet speed and input power according to the complete machine test data of the special air outlet instead of using the data of the standard air outlet.

For the calculation relationship between air volume and resistance, please refer toHow to calculate EFU rated air volume? The method in the air supply area, target wind speed and unit conversion method is to confirm the air volume of the special air outlet under the resistance condition of the whole machine. For a complete calculation method of system resistance, please refer toHow to calculate EFU working static pressure? how to add the resistance of the filter, air inlet and equipment air duct .Explain

Air flow organization: the air outlet diversion and wind speed distribution should be designed

The airflow organization of the special air outlet is the focus of customization. After the direction of the air outlet is changed, the distribution of air flow near the air outlet may be uneven; the size of the air outlet changes, and the wind speed distribution may deviate; the design of the diversion structure is unreasonable, and the air flow may drift or vortex. When customizing, confirm the air outlet diversion structure, wind speed distribution requirements and acceptance testing points, and adjust the diversion design through prototype testing if necessary.

Regarding the relationship between wind speed distribution and protection effect, please refer toWhy does the same air volume produce different cleaning and protection effects? In the description, the wind outlet direction, flow guide structure and wind speed distribution are evaluated together. For the calculation method of face wind speed, please refer toHow to calculate EFU surface wind speed? How to determine the effective filtration area and average wind speed .

Interface definition: The connection method and sealing of the air outlet must be clearly stated

The interface of the special air outlet includes the connection method and sealing requirements between the air outlet and the equipment structure. Whether the air outlet is flanged, directly connected, or a transition section is added; what is the sealing material and the pressing method; whether sealing is required between the air outlet and the internal structure of the equipment. The interface is not clearly defined, and there may be air leakage or failure to connect after installation. When customizing, the air outlet connection method, sealing material and compression method should be written into the confirmation drawing.

Regarding the coordination between the air outlet interface and the device structure, please refer toHow to confirm EFU installation seal? equipment drawings, installation conditions and acceptance methods .Verification methods in

Prototype verification: special air outlets must be tested before batch production

The special air outlet EFU is a new structure and should be prototyped or verified first. The prototype must check assembly interference, air outlet direction, air volume, static pressure, air outlet speed distribution, power, temperature rise, vibration and noise to confirm that the special air outlet does not deviate from the target performance. The prototype data and confirmation drawings are archived together as the basis for inspection of subsequent batches. If you skip the prototype and go directly to batch production, problems will be exposed in the batch stage.

In the special air outlet EFU project, Aili Industrial organizes the prototype or first unit verification according to the equipment drawings, files the assembly, performance, wind speed distribution and temperature rise data together with the confirmation drawing, and then solidifies the batch configuration. Equipment factories complete prototypes and batches within the same manufacturing system, making it easier to maintain version consistency than cross-supplier coordination. Related machines can be referred tothe EFU equipment fan filter unit page, please refer to the non-standard structure.The structure description on Customize EFU page.Customization instructions in the

Version solidification: drawings, materials and inspections must be consistent

After the prototype is approved, the confirmation drawing, bill of materials, control parameters and inspection records must be formed into a fixed version. The drawing version of the special air outlet is particularly important. If the direction, size, and diversion structure of the air outlet change, the previous prototype data may no longer be applicable. Batch execution is based on the same version, and changes must be approved and synchronized to drawings and materials to avoid configuration deviations in subsequent batches.

For projects involving non-standard interfaces, please refer toHow to customize non-standard EFU? equipment drawings, performance parameters, interfaces and prototype confirmation correspond to changes in air outlet structure and batch configuration.The version management ideas in

How to form executable confirmation results

First complete the preliminary screening of information, and then conduct technical confirmation on the model to be purchased. Include the direction, location, size, diversion structure, performance parameters, interface definition and prototype verification of the air outlet in the supplementary list. Comparison will be organized after the supplier responds. The confirmed air outlet drawings, complete machine configuration and interfaces are used for order execution. Standard air outlet parameters cannot be used to replace this project data. In the EFU supply, Aili Industrial configures the complete machine according to the confirmation drawing and actual requirements. The box, fan, filter and control correspond one by one according to the order list, which facilitates the equipment factory to customize the special air outlet EFU to the verifiable complete machine conditions.

Misunderstandings to avoid

It should be avoided to first draw the shape of the air outlet and then supplement the performance. It should be avoided to use the air volume and static pressure data of the standard air outlet. It should be avoided to only confirm the air outlet direction but not the wind speed distribution. It should be avoided to install the machine without confirming the interface and seal. It should be avoided to skip the prototype and go directly to batch. The core of EFU customization for special air outlets is not the special shape of the air outlet, but that the air outlet direction, airflow organization, performance parameters and interfaces can form a verifiable closed loop. Aili Industrial can first form a to-be-confirmed list according to the equipment drawings, listing the air outlet, performance and interface conditions together.

Related questions and answers

Can non-standard EFU skip the prototype and go directly to batch production?

For new structure or new interface projects, it is recommended to verify the prototype or the first unit first, and then solidify the batch configuration after confirming the performance and assembly.

How to promote EFU customization of special air outlets when the project information is incomplete?

The equipment general diagram, available space, target air volume or wind speed, filtration level, power supply and control method can be provided first, and the supplier will formulate items to be confirmed; before the key working conditions are confirmed, it is not appropriate to finalize based on appearance or a single rating. Aili Industrial can first form a to-be-confirmed list according to the equipment drawings, listing the air outlet, performance and interface conditions together.

What specific information do I need to prepare for this question?

Prepare current project materials around confirmation diagrams, performance conditions, prototype verification and version solidification. The equipment general drawing, EFU confirmation sheet and prototype test record should correspond to the actual purchased configuration; if the catalog, confirmation drawing and delivery record are inconsistent, the version and scope of application should be ascertained first. When customizing special air outlet EFU, you can refer to the structure and performance supporting instructions provided by Aili Industrial according to the model.
