What parameters should be focused on testing for the FFU prototype? How to judge whether the manufacturer is qualified for batch projects?
Direct answer: The FFU prototype should focus on checking the air volume, static pressure, wind speed uniformity, filter efficiency and resistance, sealing, power consumption, noise, control functions and installation and maintenance conditions under the design working conditions. After the prototype is qualified, it should also be confirmed whether the manufacturer can stably implement the same configuration, testing methods and performance requirements into batch products.
When purchasing FFU for clean room and equipment-side projects, prototypes are a step to connect product information with actual working conditions. It is not only used to confirm a single unitWhether the FFU fan filter unit can operate is also used to find out whether there is a match between the fan, motor, filter, box and control system. If you only check the appearance and nominal maximum air volume, problems such as insufficient air supply, incompatible control, or difficulty in maintenance may still occur after batch installation.
First fix the prototype test conditions
Before testing the prototype, the target air volume, installation method, power supply, operating gear, filter configuration and resistance conditions should be clarified. The test report should also indicate the location and method of measurement. Only if the prototype and the product to be delivered have the same configuration can the prototype data be used as a reference for batch projects.
in particularHEPA or ULPA filters should be of project-specified model or equivalent configuration confirmed by technical agreement. After changing to a different filter, the air volume and fan operating point may change, and the original prototype data needs to be rechecked.
What should we focus on in terms of prototype performance?
First check the static pressure at the target air volume instead of directly comparing the two independent values of 'maximum air volume' and 'maximum static pressure'. Then check the outlet wind speed and uniformity, and confirm the power consumption and noise of the prototype at the design level.
The filtration system should check filter specifications, testing data, installation seals and replacement methods. For equipment-side or space-limited projects, the dimensions, air inlet and return paths, wiring locations, and maintenance space should also be checked under actual interface conditions.
The control function should be verified according to the project plan
For projects that require single unit speed regulation, the speed regulation range and operating status should be checked; for projects that require partitioned or centralized management, agreed functions such as communication interfaces, address settings, and fault feedback should also be verified. If you plan to configureFor the FFU group control system , the compatibility of FFU and the control solution should be confirmed during the prototype stage to avoid dealing with interface problems after batch installation.
If the prototype is qualified, how to judge the manufacturer's batch capacity?
Manufacturer evaluation should not stop at prototype demonstrations and quotes. The matching capabilities of fans, motors, controls, sheet metal and filters should also be checked, as well as component testing, complete machine testing, batch consistency, non-standard response, delivery and after-sales arrangements.
Aili Industrial can match the entire FFU machine based on the project's installation size, target air volume, filtration requirements and control methods. For batch projects, it is recommended to write the confirmed configuration, test conditions, key performance and allowable deviations of the prototype into the technical agreement, and then inspect the batch products according to the agreed method. In this way, the prototype test results can become a common basis for subsequent procurement and acceptance. Specific performance is subject to actual measurement data under project conditions.
Q: If the air volume of the prototype reaches the standard, can it be purchased directly in bulk?
Answer: Filter, static pressure, uniformity, control, installation and maintenance conditions should also be confirmed, as well as testing and consistency requirements for batch products.
Q: Can prototypes and batch products use different filters?
Answer: If the configuration changes, the filter resistance, fan operating point and overall air volume should be rechecked and confirmed in the technical agreement.
Q: What materials should be prepared when requesting a prototype from Aili Industrial?
Answer: It is recommended to provide application scenarios, installation drawings, target air volume and static pressure, filtration requirements, power supply, control method, estimated quantity and test conditions.
