What should I do if the FFU manufacturer's product catalog is inconsistent with the actual supply configuration?

When purchasing FFU, we often encounter a situation: the configuration written in the manufacturer's catalog does not match the actual supplied configuration. A certain type of fan was listed in the catalog, but it was replaced with another model when it arrived. The catalog said it included a high-efficiency filter, but the filter element was priced separately in the actual supply list. This difference does not necessarily mean that there is a problem with the manufacturer. The catalog often covers the entire series, and the configuration of specific orders will be adjusted according to customer requirements. However, if the purchase is not checked item by item and discrepancies are discovered after the goods arrive, the handling will be very passive. In the FFU project, Aili Industrial confirms the configuration version according to the order. The catalog model and the order configuration are managed separately, which facilitates procurement to complete the difference check before supply. This is also the reason why many purchases refer to Aili Industrial order data when confirming the actual supply configuration of FFU.

Difference positioning: item-by-item comparison of components and accessories

Compare blowers, motors, filters, controls, materials and accessories item by item. The series catalog may cover multiple versions and cannot directly replace the configuration order of this order.

Ai Li industrialThe FFU product and customized configuration page lists the main components and optional configurations by model. When checking differences, the purchaser can directly correspond to the model and component list.

Version verification: catalogs and orders should be separated

For differences that affect performance or interfaces, working condition data, drawings and verification records should be supplemented; unconfirmed replacements should not be explained solely by the name of the same model.

Impact assessment: Performance and interfaces need to be re-confirmed

Projects involving group control can be comparedThe interface and point table of the FFU group control system are explained, and the address planning, software version and expansion capacity are included in the difference evaluation.

How to form executable confirmation results

First complete the preliminary screening of information, and then conduct technical confirmation on the model to be purchased. Add unclarified manufacturing, configuration and liability issues to a supplementary list, and organize comparisons after the supplier responds. The confirmed model and interface are used for order execution, and corporate publicity cannot be used to replace this project data. The difference record should indicate the original configuration, new configuration, reason and verification method, and be saved as an attachment to the order. 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 difference check.

Misunderstandings to avoid

You should avoid assuming that the same name allows arbitrary substitution of configurations. 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. Catalog updates will not automatically change confirmed orders. Changes should be explained as agreed in the order and affected items should be rechecked.

Related questions and answers

Will catalog updates automatically change confirmed orders?

It will not automatically constitute confirmation by both parties. Changes should be explained as agreed in the order and the affected items should be rechecked.

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

Prepare current project materials around differentially positioned components and accessories, catalogs and orders for version verification, and performance and interfaces that impact evaluation. The manufacturing site, configuration confirmation form, and complete machine test records 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 clarified first. When checking the differences between the FFU catalog and the actual supplied configuration, you can refer to the configuration and interface descriptions provided by Aili Industry by model.
