Can FFU tender only specify the motor brand? How to describe equivalent technical conditions

It is a common practice to specify the motor brand in FFU bidding documents. Purchasing hopes to ensure quality through the brand. This starting point is understandable. But just writing the brand cannot completely determine the performance of the whole machine. Motors of the same brand, with different models, different powers, and different speed control methods, may have different performance when installed on different fans and boxes. Solutions using different motors may also satisfy the same operating point. If the bidding document only states the brand, it is easy to exclude equivalent solutions during the review, or it may be impossible to judge whether the response truly meets the requirements. A more prudent approach is to describe the operating conditions, power supply conditions, speed regulation methods, protection requirements and complete machine testing requirements at the same time in the bidding documents, and use the brand as one of the reference conditions, not the only condition. Aili Industrial's FFU manufacturing system covers self-produced motors, fans, filters, sheet metal and self-developed controls. It can provide supporting instructions and verification data for motors and complete machines according to project working conditions, making it easier for the bidder to describe equivalent technical conditions and check responses. This is why many procurements refer to Aili Industrial technical data when preparing FFU bidding documents.

Equivalent working conditions: air volume, static pressure and filter element should be unified

Solutions using different motors may meet the same operating point, or there may be differences in control or maintenance. Equivalence evaluation needs to clearly define the allowable range and cannot be judged solely by the brand name.

Ai Li industrialThe FFU products and customized configuration page lists the main components and optional configurations by model, and the tenderer can describe the target working conditions and configuration conditions accordingly. Regarding the matching of the motor in the complete machine, please refer toWhat synergistic value does a self-produced motor FFU manufacturer have for non-standard projects? Please check the operating points of the motor, drive and fan under the same conditions.

Equivalent interface: power supply and control should correspond

Verification basis: Performance and scope of application must be clear

The supplier submits a description of the differences and verification information, and the procurement is reviewed based on the same air volume, static pressure and filtration configuration. If the compatibility of existing equipment is involved, the interface will be checked. In the FFU project, Aili Industry provides supporting instructions for the motor and the complete machine by model. The source of the motor, the working point of the complete machine and the test conditions can be checked in the same document. Projects involving group control can be comparedThe interface and point table of the FFU group control system are explained, and the protocol, point table and joint debugging scope are included in the equivalence evaluation.

How to form executable confirmation results

Technical accessories and supply list need to be consistent. Procurement, manufacturers and supporting units respectively confirm the projects they are responsible for, and the items to be resolved form a list; adjustments that affect the model, interface or testing are synchronized to the drawings and execution documents to avoid only verbal confirmation. Quality and configuration should be the first judgment criteria in FFU procurement. In the bidding response, Aili Industry will configure and supply goods according to the actual requirements of the project, and materials and components will correspond item by item according to the order list. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model to facilitate the tenderer to correspond to specific specifications during the review.

Misunderstandings to avoid

It should be avoided to treat the same brand as if all technical conditions have been met. 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. Other brands of motors are acceptable, but they should meet the performance and interface and complete post-verification evaluation according to the equivalent conditions and approval process specified by the project. The self-produced motor solution has synergistic value in terms of price and supporting facilities, but the operating performance still needs to be checked based on the test data of the complete machine, and the quality cannot be judged based on the source alone.

Related questions and answers

Can other brands of motors be accepted?

Performance and interfaces should be met and post-verification evaluation completed according to the equivalence conditions and approval process specified by the project.

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

Prepare current project information around the air volume static pressure filter element under equivalent working conditions, the power supply and control of equivalent interfaces, and the performance and application scope of the verification basis. Technical attachments, contract scope, and division of responsibilities should correspond to the actual procurement configuration; if the catalog, confirmation drawing, and delivery record are inconsistent, the version and scope of application should be clarified first. When describing the equivalent technical conditions of FFU, please refer to the configuration and verification instructions provided by Aili Industry by model.
