FFU manufacturers make their own filters. What supporting conditions should be checked when purchasing?

FFU manufacturers make their own filters, which is often seen as an advantage. 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, without the need to transfer data back and forth between the complete machine factory and the filter element factory. But homemade products also have another side: passing the filter element does not mean it will pass the test after being installed in the complete machine. The sealing, compression method, and replacement space of the filter element and box need to be confirmed separately. Procurement cannot skip these checks just because they are produced by the same manufacturer. Aili Industrial covers filters and complete machine assembly in FFU manufacturing. Filter information and complete machine test conditions can be put in the same document for verification by model. This is why many purchasers refer to Aili Industrial product data when evaluating the capabilities of FFU's self-made filters.

Filtration performance: efficiency and resistance should correspond to the working conditions of the whole machine

The filter element model is required to correspond to the complete machine model, and the effective filtration area, initial resistance, and installation and compression method must be checked. Just because the filter element is qualified does not mean that the installed seal is automatically qualified.

Ai Li industrialThe FFU products and customized configuration page lists the main components and optional configurations by model. When checking the filtration performance, the purchaser can directly correspond to the model and filter element configuration. For the difference between filtration level and efficiency, please refer toAs explained in What is the Difference between Cleanliness Level and Filtration Efficiency ? Record the space level and filter efficiency separately during maintenance.

Mechanical fit: Dimensions and compression must be confirmed item by item.

When the filter material or size changes, the fan operating point and maintenance structure should be evaluated. The delivery materials separately list the filter element information and complete machine test conditions to facilitate subsequent replacement.

Maintenance cooperation: replacement and spare parts must be compatible

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 the maintenance package.

How to form executable confirmation results

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 to facilitate procurement and corresponding specific specifications in self-made filter projects.

Misunderstandings to avoid

You should avoid thinking that interface confirmation is not required if the products are produced by the same manufacturer. 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. You can evaluate the use of filter elements from other manufacturers, but you must check the size, sealing, resistance and verification after replacement. You cannot buy based on appearance alone.

Related questions and answers

Can I use filters from other manufacturers?

Can be evaluated, but size, sealing, resistance and verification after replacement must be checked, not purchased based on appearance alone.

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

Prepare current project information around the efficiency and resistance of filtration performance, size and compression of mechanical fit, replacement and spare parts of maintenance fit. 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 the ability of FFU manufacturers to make their own filters, you can refer to the instructions provided by Aili Industrial for filter elements and complete machines by model.

Key points for selection and acceptance inspection

Aili Industrial FFU selection and procurement support

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.
