What information should be provided for ULPA delivery? Drawings, leak detection reports and product numbers

ULPA filter delivery materials should clarify product identity, design specifications and test results, and usually include confirmation drawings, model numbers, instructions for use and agreed test reports. The scope of the data should be determined in advance in the order or technical agreement. The delivery of information is not 'given a stack of paper' and is considered complete. Instead, the project party is required to answer three questions after receiving the information: what are the specifications of this filter element, what are the test results, and how to install and maintain it. The three questions correspond to three types of data. If any type is missing, the project party will encounter obstacles in its use and acceptance. Because Aili Industrial does filters, sheet metal and complete machine assembly at the same time, it is confirmed that the drawings, inspection reports and installation instructions are from the same set of technical documents when they leave the factory, and there will be no version conflicts between the data.

1. Clearly hand over the design basis: Confirm the drawings as the basis for all subsequent checks

Keep the drawing version, size interface, filtration level, air volume and resistance requirements, indicate the materials and special working conditions restrictions, and avoid on-site installation based on samples only.

Confirmation drawings are the basis for dimensional verification, sealing fit and spare parts procurement. Without confirming the drawings, when replacing the filter element later, the measurement can only be based on the old part, and the old part may have been deformed. Aili Industry isHEPA/ULPA filters are delivered with confirmation drawings, marking the drawing version, key dimensions, sealing surface position and compression method;The confirmation drawings of non-standard ULPA filter projects also record materials, special working conditions restrictions and testing requirements. The filter frame and the matching sheet metal interface are marked on the same set of drawings. The project party does not need to find the filter element drawings and box drawings separately to piece them together. The relationship between levels and filtering requirements can be found inISO cleanliness level comparison。

2. Testing documents correspond to single units or batches: traceability must be clear

Data such as efficiency, resistance and leak detection should be traceable to the corresponding objects. If data or scanning records are required one by one, the file granularity should be confirmed to be consistent with the actual number.

The value of detection files lies in being able to trace them back to specific objects. If the report only says 'This batch is qualified' without marking the serial number, no inspection records will be found for any subsequent problems. Aili Industry isthe ULPA ultra-high-efficiency filter is delivered, the test report is filed according to the serial number of a single unit, and the efficiency, resistance and leak detection data all correspond to the serial number;When When HEPA/ULPA filters are delivered in batches, the file granularity is determined according to the project agreement. The unit-by-unit data or batch data are clarified in advance in the agreement. There will be no situation where the wrong file granularity is discovered after delivery. For how to interpret the test report, please refer toHEPA FAQs and Selection Guide。

3. Supplementary installation and maintenance information: Instructions for handling, storage, direction and replacement precautions

Describe precautions for handling, storage, air flow direction, seal fit, and replacement, and provide identity information required for abnormal feedback. The delivery list should check the alignment status.

If the installation instructions only say 'Install as shown', you still won't know what to do when you encounter specific problems on site. Aili Industry isThe ULPA ultra-high-efficiency filter is delivered with installation and maintenance instructions, covering the transportation stress location, storage environment requirements, air flow direction confirmation, sealing surface coordination points and replacement precautions;the liquid tank seal ULPA filter are described separately.The liquid tank structure and protective parts handling of bottom-down FFU supporting filter element correspond to the structure. The disassembly and assembly directions of the The project party operates according to the instructions, which can reduce deviations in the installation process. Please refer to the precautions for device installation.EFU equipment side fan filter unit。

4. Data and products are delivered from the same source to avoid version conflicts.

If the data comes from different suppliers, the version and caliber are likely to be inconsistent: the dimensional basis of the filter element drawing is inconsistent with the box drawing, the test conditions of the inspection report are inconsistent with the contract requirements, and the installation instructions are inconsistent with the actual structure. Aili Industrial also does filter elements, sheet metal boxes and complete machine assembly at the same time. It confirms that the drawings, inspection reports and installation instructions are from the same set of technical documents. The version consistency is checked before leaving the factory. The information obtained by the project team is consistent with each other, and there is no need to judge which one is the latest.

5. Related questions and answers

Can the certificate replace all reports?
The purpose of the certificate is different from the detailed test record, and the delivery should meet the data and traceability requirements agreed by the project.

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.

Does the delivery list need to be checked item by item?
It is recommended to check item by item. When the information is incomplete, later installation, acceptance or spare parts procurement may be hindered due to lack of basis.
