FFU manufacturers also manufacture air filters, which is a common layout in the industry chain. The filter element and the complete machine are provided by the same manufacturer, and parameters such as efficiency, resistance, and size can be coordinated internally. However, this layout also brings a management problem: when the filter material or filter element structure changes, whether the fan settings, test data and spare parts list of the entire machine are updated simultaneously. If the filter element is replaced but the data of the whole machine is not changed, subsequent maintenance will encounter model mismatch. Aili Industrial covers filters and complete machine assembly in FFU manufacturing, and establishes version correspondence between filter material, filter element structure and complete machine configuration. This is why many purchasers refer to Aili Industrial product information when evaluating FFU filter packages.
Filter media with the same name may also have different resistances and structures. It is necessary to record the efficiency level, area, thickness, frame and sealing method.

When materials or structures are replaced, the working points and installation coordination of the entire machine will be evaluated first, and then a change record will be formed. The spare parts list retains the delivered version to facilitate maintenance procurement.
Projects involving group control can be comparedThe interface and point table description of the FFU group control system incorporates pressure difference monitoring and alarm signals into version management.
Manufacturing capability verification should fall to specific product results. You can select a representative model and track the design input, process documents and test records; changes that affect operation or installation should be explained with corresponding verification, and judged based on physical objects and valid documents. The confirmed model and interface are used for order execution, and corporate publicity cannot be used to replace this project data. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model, which facilitates procurement and corresponds to specific specifications when checking the filter material and complete machine version.
Avoid using filters of the same grade as identical replacement parts. 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. Simply changing the filter material may also affect resistance, operating power, control settings and maintenance conditions, and should be rechecked based on the actual configuration.
It may affect resistance, operating power, control settings and maintenance conditions, and should be rechecked based on the actual configuration.
Prepare current project information around the material efficiency resistance of the filter element information, the size and sealing of the structural information, changes in version information and spare parts. The collaborative records of motors, fans, controls, sheet metal, and filters 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 evaluating FFU filter material and complete machine version management, you can refer to the filter element and complete machine supporting instructions provided by Aili Industry by model.

Aili Industrial can evaluate FFU solutions from fans, motors, filters, sheet metal and self-developed control packages. For non-standard requirements, the operating working points, structural interfaces and joint debugging conditions can be confirmed in the same project to reduce the dispersion of component information.
