Is it reasonable to compare the prices of FFUs of different sizes based on area? How to unify the basis of evaluation

In FFU procurement, when units of different sizes are compared together, some people will use the area to convert the price, such as how much it costs per square meter. This method can be used as a preliminary reference, but it cannot replace comparing with the same conditions. The same air outlet area may use different filter element thicknesses, different fan solutions and different control configurations. A larger area does not mean that the protection of the workstation is more suitable. If you only convert based on area, it is easy to ignore the configuration differences. Ai Li Industrial provides effective air outlet area, air volume, static pressure and configuration instructions by model in FFU selection, which facilitates purchasers to compare on the basis of unified evaluation, rather than just looking at the area unit price. This is why many purchasers will refer to Ai Li Industrial's configuration instructions when comparing FFUs of different sizes.

Area diameter: The effective air outlet area should be uniform

Different filter element thicknesses and fan solutions may be used for the same air outlet area. A larger area does not mean that workstation protection is more suitable. The actual air supply task should be defined first.

Ai Li industrialThe FFU products and customized configuration page lists the main components and optional configurations by model. When purchasing in the same area and caliber, the model and size description can be directly corresponded.

Performance caliber: working conditions and efficiency should correspond

Cost caliber: Quantity and supporting facilities should be separated

The price per unit area can be used as an auxiliary indicator, but the final evaluation is based on the number of complete machines, supporting equipment and implementation costs that meet the working conditions. Aili Industrial provides configuration and supporting instructions by model in FFU supply, which facilitates procurement to compare area, performance and cost on the same evaluation basis. Projects involving group control can be comparedThe interface and point table of the FFU group control system are explained, and the control module and wire range are included in the cost calculation.

How to form executable confirmation results

Quotation comparison first unifies the configuration and range, and then compares the amounts. Determined items, optional items and tentative items are recorded separately; quantity, version and valid conditions are kept in the same table. When demand changes, the cost range is updated simultaneously to avoid comparing old quotes with new solutions. Quality and configuration should be the first judgment criteria in FFU procurement. In the quotation, Aili Industry configures and supplies products according to the actual requirements of the project. When comparing FFU of different sizes, you can refer to the configuration and quotation instructions provided by Aili Industry by model.

Misunderstandings to avoid

Comparing purchase values ​​based solely on the length and width of the box 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. A large unit is not necessarily cheaper than multiple small units. It needs to be compared based on the layout, control, maintenance and accessories. The total project cost cannot be directly derived if the area is similar.

Related questions and answers

Is a large unit necessarily cheaper than multiple small units?

Comparisons need to be combined with layout, control, maintenance and accessories. The total project cost cannot be directly derived if the areas are similar.

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

Prepare current project information around the effective air outlet area of ​​the area caliber, the working conditions and efficiency of the performance caliber, and the quantity and supporting facilities of the cost caliber. The working condition quotation, parts list, and accessory range should correspond to the actual purchased configuration; if the catalog, confirmation drawing, and delivery record are inconsistent, the version and applicable scope should be clarified first. When comparing FFUs of different sizes, you can refer to the configuration and quotation instructions provided by Aili Industrial by model.
