What installation dimensions are required for non-standard ULPA? Interface diagram and direction annotation

Non-standard ULPA filters need to provide dimensions such as shape, installation opening, sealing interface, fastening method and air flow direction. A clear interface diagram is more conducive to reducing rework than just reporting the width, height, and thickness. There is no standard sample to compare with for non-standard customization. If one direction or benchmark is missing on the drawing, the produced filter may not fit into the equipment. Aili Industry isULPA filters can provide drawing verification support to reduce rework at the interface level.The non-standard customization and sample matching of

1. Mark the complete interface information

Drawings should contain datums, units, view orientation, critical tolerances, and revisions. The positions of liquid tanks, flanges, gaskets and pressing parts need to be clear and cannot be confirmed with just an appearance photo.

If the benchmark is not written clearly, the dimensional data cannot be reviewed; if the version is not indicated, different batches may be produced according to different drawings. Please refer to the key points of interface labeling of the liquid tank structure.ULPA ultra-high efficiency filter FAQ and selection guide。

2. Supplementary equipment constraints

Describe the available depth, disassembly and assembly channels, air inlet space and test probe operating space. Thin equipment especially requires checking the assembly relationship between the fan and the filter element at the same time.

If only the size of the filter element is marked but not the equipment constraints, there will be a situation where 'the filter element size is correct and cannot be installed in the equipment'. Please refer to the space restrictions for internal installation of the equipment.the fan filter unit on the EFU equipment side .Instructions related to

3. Direction marking cannot be omitted

When there are mirror installations of the left and right modules of the same device, the air flow and interface directions should be marked on the drawing, and one model cannot be simply copied. If the direction is wrong, the filter and fan may be installed backwards, changing the airflow path.

The air flow direction, loading direction and sealing surface orientation should be marked separately. The direction requirements for ceiling installation can be combined withFFU fan filter unit .Structural verification of

4. Use samples to confirm the fit and then solidify the batch drawings

Check the trial assembly, sealing and test accessibility according to the confirmation drawing, and then solidify the batch drawing. Temporary modifications on site should be fed back simultaneously to avoid using separate sets of drawings and physical objects.

Aili Industry isFor non-standard ULPA filter projects, sample parts can be made first, and the batch can be arranged after confirming that loading, sealing and leak detection are possible.

5. Related questions and answers

What to do if you don’t have old drawings?
You can first measure and map the equipment interface and check the actual object, but the size information confirmed by both parties should be formed before production. When placing an order based solely on on-site descriptions, the risk of rework is high.

Can photos replace interface diagrams?
Photos help confirm the structure, but information such as datums, tolerances, directions and versions cannot be fully expressed through photos, and drawings are still needed for key matching dimensions.

Why are the direction markings emphasized separately?
Mirror installation and airflow direction errors will not be reflected in the dimensions, but will affect the installation and airflow path, which must be marked separately on the drawings.
