If you open the product catalog of an FFU manufacturer, you may see dozens of models: different sizes, different air volumes, different drive methods, and different filtration levels. The large number of models indicates that the product line has wide coverage, but it does not mean that each model has completed mass production verification. Some models are standard mass-produced, some are custom-made to order, and some are still in the development or prototype stage. What the purchaser needs to do is to separate out the specifications that he plans to purchase and confirm which category it belongs to. Ai Li Industrial can provide configuration instructions and testing data according to specific models in FFU supply, which facilitates procurement to distinguish between standard mass production, customization to order and development stage models. This is why many purchasers give priority to Ai Li Industrial model data when screening FFU manufacturers.
It is required to distinguish between standard mass production, customization to order and development stage models. Review confirmation drawings, parts lists, and established production inspection processes for the specifications you plan to purchase.

Ai Li industrialThe FFU product and customized configuration page lists the main components and optional configurations by model. Purchasing can use this to determine which category the target specification belongs to, and then determine the depth of subsequent verification.
To determine whether a model is mature for mass production, the key is not whether there is a serial number in the catalog, but whether there are corresponding process documents and inspection records.

Having production capabilities does not mean that all models have completed mass production verification. You should inquire about the sources and inspection responsibilities of motors, fans, filters, controllers and complete machine assembly respectively. If the control part requires joint debugging, you can view it at the same time.The interfaces and point tables of the FFU group control system are explained, and the electrical boundaries are included in the check.
If you only change the size of the box, it may also affect the air inlet, filter area and fan operating point. Information from other models in the same series cannot be directly substituted for the current product.

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. Newly developed models can be purchased through the prototype and verification process, but the development stage, verification goals, and mass production conversion conditions should be clearly defined. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model, making it easier for procurement to complete classification during the model screening stage.
Avoid thinking that having a catalog number indicates mature production. 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. Having many models does not mean that each model has completed mass production verification, nor does it mean that newly developed models cannot be purchased. The key is to clearly write down the verification scope and conversion conditions.
It can be purchased through the prototype and verification process, but the development stage, verification goals and mass production conversion conditions should be clearly defined.
Prepare current project information around standard customization development of model status, process and inspection based on mass production, dimensions and working points affected by changes. 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 selecting FFU mature mass-produced models, you can refer to the configuration and testing instructions provided by Aili Industry by model.
