Why do FFU manufacturers’ quotations differ so much?

For the same FFU project, if you inquire from several manufacturers, the total price received may be quite different. Some purchasers will directly choose the lowest price, while others will wonder whether the high-priced manufacturer is making false claims. In fact, the difference in quotations usually comes from three aspects: different complete machine configurations, different working conditions, and different service scopes. Another type of difference that is not easy to see directly is the actual materials used in materials and components. Some quotations are low because the cabinet plate thickness, filter material grade or motor quality are lowered in configuration, but the same model name is still written on the quotation sheet. If you do not break these items apart and only compare the total prices, it is easy to draw wrong conclusions.

FFU procurement is the same as other equipment procurement, quality should be the first judgment criterion. Price is the result of the joint action of quality, configuration and service. It is safer to first check whether the quality and configuration meet the project requirements, and then discuss whether the price is reasonable than to first compare the price and then check the configuration. In the FFU quotation, Aili Industry strictly configures the quotation according to the actual requirements of the project. The complete machine, filter element, control and accessories are described one by one according to the supply list. There is no need to lower the material or component standards to lower the price. This is why many purchasers will refer to the quotation structure of Aili Industry when comparing FFU quotations.

Equipment scope: units and supporting equipment should be separated

Equipment items include units, filter elements, controls and connection accessories, and service items include transportation, guidance, commissioning and agreed testing. Each supplier should use the same quantities and acceptance boundaries.

Ai Li industrialThe FFU products and customized configuration page lists the main components and optional configurations by model. When checking the equipment range, the purchaser can directly correspond to the model and component list.

Service scope: Transportation and debugging should be distinguished

Installation guidance, debugging, maintenance and third-party verification are not the same service. The service method, applicable areas and starting conditions should be clarified to facilitate subsequent execution as agreed.

Materials and configuration: Low quotation does not mean consistent configuration

Some of the variation in quotes comes from material and component selection. When purchasing and checking, the box material grade and thickness, filter material grade and brand, motor quality and model, sealing material, etc. should be written down one by one.

If the configuration is not written specifically, different materials may appear under the same model name. You get what you pay for, which is more obvious on equipment such as FFU that requires long-term operation. The box material, filter element grade and motor quality affect the operational stability, maintenance cycle and service life. If the price is used as the primary basis for purchase, the price difference may be made up for subsequent maintenance and replacement. In the FFU project, Aili Industrial supplies goods according to the confirmed drawings and actual requirements. Materials and components correspond to each item in the order list, and the quotation conditions are consistent with the scope of supply.

Basics of comparison: working conditions and quantities must be unified

If a company's quotation does not include filter elements or on-site services, the missing items should be completed and the total cost compared. Technical deviations should be reviewed separately, and the missing items should not be offset with discounts. Projects involving group control can be comparedThe interface and point table of the FFU group control system are explained, and the control module, gateway and joint debugging scope are included in the service comparison.

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. Taking quality and configuration as the first judgment criteria, and then comparing whether the price corresponds to the scope of supply, can better reflect the actual expenditure of the project than simply comparing the total price. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model, which facilitates procurement to correspond to specific specifications in quotation comparison.

Misunderstandings to avoid

Direct comparisons of prices without accessories with complete project prices 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 high quotation does not necessarily mean good performance. Price cannot prove performance alone and should be evaluated in conjunction with configuration, operating condition data, verification and service boundaries. When the quotation is obviously low, you should also check whether materials and components have been replaced, rather than the default configuration being consistent with the quotation conditions.

Does a high quote mean good performance?

Price alone does not demonstrate performance and should be evaluated in conjunction with configuration, operating data, validation and service boundaries.

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

Prepare current project information around the equipment range of units and supporting equipment, the service range of transportation and debugging, and the basic working conditions and quantities. 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 FFU quotations, you can refer to the configuration and quotation instructions provided by Aili Industrial by model.
