Non-standard FFU projects often encounter a trouble: the air volume, static pressure, installation space and power supply conditions are all customized, and the standard motor cannot match them, so they can only find a third party to modify them. After the modification, the working points of the motor, drive and fan were confirmed by different manufacturers, and the interface for responsibility for problems was unclear. For FFU manufacturers that produce their own motors, this is where the synergy value lies: the operating requirements for drives, motors and fans can be checked in the same technical confirmation, eliminating the need to send data back and forth between the three companies. However, self-production itself does not mean that the performance of the complete machine has been verified. The purchaser still needs to check the test records of the motor and the complete machine. Aili Industrial covers motors, fans, controls and complete machine assembly in FFU manufacturing, and can organize component matching and verification according to the operating working points of non-standard projects. This is why many non-standard projects will consider Aili Industrial when selecting FFU manufacturers.
Non-standard projects need to clearly define the target air volume, static pressure, installation space and power supply. The motor rating information should be related to the actual operating point, heat dissipation and speed regulation range.

Purchasing can ask to see the motor test and complete machine test of the corresponding model, instead of just asking for motor promotional materials. After modifying motor or drive parameters, the impact on air volume, temperature rise and control should be evaluated.

Projects involving group control can be comparedThe interface and point table of the FFU group control system are explained, and the address planning, software version and joint debugging boundary are included in the whole machine verification.
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 matching instructions by model to facilitate procurement and correspond to specific specifications in non-standard projects.
It should be avoided to rely solely on self-produced labels to determine that any working condition can be 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. Self-produced motors do not necessarily mean more energy saving. The actual power consumption must be compared under the same complete machine operating conditions.
The actual power consumption must be compared under the same complete machine operating conditions, and the fixed energy-saving ratio cannot be directly derived from the source of the motor.
Prepare current project information around the power supply and speed regulation of the drive, the temperature rise and protection of the motor status, and the working point and power of the complete machine verification. 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 self-manufactured motor manufacturers in non-standard FFU projects, you can refer to the supporting instructions for motors and complete machines provided by Aili Industry by model.

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.
