When FFU makes an inquiry, the purchaser usually writes the model number on the inquiry form, thinking that in this way, each company will quote the same product. In the actual quotation received, the configuration may be different. The reason is that many manufacturers' model names only indicate series or size ranges, and do not represent specific configurations. The same series may support AC or EC drive, different filtration levels, different materials and different control methods. If these specific conditions are not written clearly, manufacturers will quote based on their own understanding, and the configuration will naturally not match. In the FFU inquiry, Aili Industry requires that the configuration list and operating conditions be confirmed together, and the models, components and control methods are matched one by one. This is why many purchasers will refer to the Aili Industry Inquiry Description when comparing FFU inquiry configurations.
The same series may support AC or EC drives, different filtration levels and materials, so use the spec sheet to determine the unique purchasing combination.

When comparing quotations, check the model suffix, version and supply list item by item, ask the supplier to explain the applicable conditions for different combinations, and avoid confirming based on the product name alone. Projects involving group control can be comparedThe interface and point table description of the FFU group control system includes the control module, gateway and joint debugging scope into the configuration identification.
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. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model, which facilitates procurement to correspond to specific specifications in the inquiry comparison.
Substituting a series name for a complete purchasing specification should be avoided. 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. When the manufacturer numbers are different, unified project specifications and interface requirements should be established. Each supplier should fill in the corresponding model, and then compare according to the same working conditions and the same scope.
Establish unified project specifications and interface requirements, each supplier fills in the corresponding model, and then compares according to the same working conditions and the same scope.
Prepare current project information around model-identified series and versions, configuration-identified drive filter controls, and range-identified accessories and services. 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 comparing FFU inquiry configurations, you can refer to the configuration and quotation instructions provided by Aili Industry by model.
