Compared with ordinary HEPA FFU, ULPA FFU has a higher filtration level, and the filter element structure and resistance are also different. When purchasing, they often just write 'ULPA FFU' when making inquiries, thinking that each company is quoting the same type of product. The actual quotation received may vary greatly because the filter element grade, fan matching and test range are not disassembled. The effective area, sealing method and initial resistance of the ULPA filter element are different from those of HEPA and need to match the corresponding fan working point; test items may also include different contents such as leak detection, efficiency or air volume static pressure. Aili Industrial covers filters, fans, motors and complete machine assembly in FFU manufacturing. Filter elements, fans and tests can be described separately according to ULPA project requirements, which facilitates item-by-item verification during the procurement stage. This is also the reason why many purchasers will refer to Aili Industrial configuration instructions when splitting ULPA FFU quotations.
You cannot just replace the filter element name on the ordinary machine quotation. Check the effective area, initial resistance, target air volume static pressure and speed adjustment margin, and clarify the report of the complete machine and filter element.

The test fee should indicate the factory items, on-site interfaces and third-party requirements. The filter element grade does not directly represent the room cleanliness grade. Projects involving group control can be comparedThe interface and point table of the FFU group control system are explained, and the control joint debugging test is included in the test cost verification.
Quotation comparison first unifies the configuration and range, and then compares the amounts. Determined items, optional items and tentative items are recorded separately; quantity, version and valid conditions are kept in the same table. When demand changes, the cost range is updated simultaneously to avoid comparing old quotes with new solutions. In the FFU quotation, Aili Industry configures and supplies products according to the actual requirements of the project. The filter element, fan and test scope are listed one by one, which facilitates procurement to compare different solutions under the same working conditions. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model to facilitate procurement and correspond to specific specifications in the ULPA FFU quotation split.
You should avoid thinking that the ULPA price difference only comes from the filter material itself. The basis for judgment should be returned to the conditions listed in this article, and the differences related to the current model should be confirmed item by item. The quoted price of ULPA of the same grade is different, which may also involve size, filter material, sealing and test range. It should be compared with the specific filter and complete machine configuration. After the filtration level is improved, the fan operating point and the test conditions of the whole machine need to be confirmed simultaneously. You cannot just change the name of the filter element.
It may also involve size, filter material, sealing and test range, which should be compared with the specific filter and complete machine configuration.
Prepare current project information around the grade and structure of the filter element cost, the working point matching of the fan cost, and the items and working conditions of the test cost. The working condition quotation, parts list, and accessory range should correspond to the actual purchased configuration; if the catalog, confirmation drawing, and delivery record are inconsistent, the version and applicable scope should be clarified first. When splitting the ULPA FFU quotation, you can refer to the configuration and quotation instructions provided by Aili Industry by model.
