How do FFU manufacturers compare? Create a supplier comparison table using the same working conditions

When comparing FFU manufacturers, the most common mistake is to compare data under different working conditions together. Units with similar rated air volumes may use different filters, different rotation speeds or different external static pressure conditions. If these conditions are not aligned, it may appear that you are comparing products, but you are actually comparing test calibers. Aili Industrial provides target air volume, static pressure and filter element supporting instructions for specific models during FFU selection, which facilitates procurement and establishing a supplier comparison table based on the same working conditions. This is why many clean engineering companies give priority to Aili Industrial product data when comparing FFU manufacturers.

Unified working conditions: air volume, static pressure, and filter elements are aligned first

Each supplier is required to report actual input power, supply air performance and control settings at the same target points. Only when the working conditions are unified can the data have comparative meaning.

Ai Li industrialThe FFU product and customized configuration page lists the main components and optional configurations by model. Purchasing can unify the inquiry conditions accordingly to avoid each company quoting based on different configurations.

Unified configuration: materials and control scope should be aligned

The price comparison should also unify the box, controller, installation accessories and service scope, mark the data that are not directly comparable separately, and then review after adding conditions.

Projects involving group control can be comparedThe interface and point table description of the FFU group control system incorporates address planning, wire range and joint debugging boundaries into unified comparison conditions.

Unified scope: equipment, accessories and services are divided into categories

Energy saving cannot be compared only by wattage. You should confirm that the air volume and static pressure are the same, and record the filter element resistance and actual operating mode. Otherwise, the power size does not represent the same service capability. The data of no-load high air volume and operation with filter element cannot be directly compared. Aili Industrial can provide complete machine test records and control function descriptions in FFU supply, and cooperate with procurement to complete comparisons with the same conditions.

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. It is recommended to use the same comparison table to record the operating condition data, configuration version, supply scope and service boundaries of each manufacturer, and incomparable items should be marked separately. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model, making it easier for procurement to complete comparison on the same basis.

Misunderstandings to avoid

Direct comparisons between no-load high air volume and filtered operation data 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. Catalog parameters, publicity data and actual measurement records should be managed separately and cannot be mixed in the same column for comparison.

Related questions and answers

Can I compare energy savings by wattage only?

No, the same air volume and static pressure should be confirmed, and the filter element resistance and actual operating mode should be recorded. Otherwise, the power size does not represent the same service capability.

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

Prepare current project information around air volume static pressure filters with unified working conditions, unified materials and controls, and equipment accessory services with unified scope. 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 establishing the FFU manufacturer comparison table, you can refer to the operating conditions and configuration instructions provided by Aili Industry by model.
