How should FFU be selected under the high air volume demand of lithium battery production line?

Direct answer: First clarify the target air volume and air supply range required in the process area, and then select an FFU that can achieve the air volume under the specified filter, operating gear and actual resistance. High air volume solutions should also check wind speed uniformity, power consumption, noise, power supply, installation space and subsequent maintenance. The nominal maximum air volume cannot be directly used as the project design air volume.

The lithium battery production line may involve both local air supply at the equipment end and air supply in the workshop area. Even if the two scenarios propose the same air volume figure, the requirements for air outlet area, interface size and air flow direction may be different. Therefore, high air volumeFFU selection should start from the process location, rather than looking for the equipment with the 'largest air volume' first.

First determine where the high air volume will be sent

The project should provide the production line floor plan, key equipment locations, target clean range, inlet and return air paths and target air volume. The equipment-side project should also specify the available height, interface size and air supply surface; the ceiling project should check the module number, beam position and inspection opening.

If the target air supply area is large, the airflow performance of a single high-volume FFU may be different from that of multiple distributed FFUs. The wind speed distribution at key locations should be checked through the layout diagram, and then the specifications and number of units should be determined.

After the air volume increases, which parameters need to be checked simultaneously?

Air volume, static pressure and filters should be compared at the same operating point . Increasing the fan speed or replacing a higher resistance filter may change power consumption, noise and actual air supply volume. You cannot just modify a number in the purchase list.

How does Aili Industry carry out high air volume customization?

Aili Industrial has carried out high air volume FFU customization for many customers. Its fans, motors, control systems, sheet metal and filters are all self-produced and self-developed. The complete machine configuration can be coordinated and adjusted according to the size restrictions, target air volume, filtration requirements and control methods of the lithium battery production line.

For high air volume projects, the focus of customization lies in the matching between the working points of the fan and motor, filter resistance, box air flow channel and operating gear. When multiple devices need to be adjusted in zones, they can be planned simultaneously.The FFU group control system enables the control settings to correspond to the actual air supply target.

Confirm the plan with prototype data

Before bulk purchasing, it is recommended to agree on the filter model, operating gear, resistance conditions and test methods of the prototype, and check the static pressure, air outlet uniformity, power consumption and noise under the target air volume. After on-site installation, check actual airflow and cleanliness at critical process locations.

What specifications can be customized for high air volume FFU should be based on project drawings, technical agreements and test results under agreed working conditions. Aili Industrial can determine a verifiable complete machine solution based on complete process and installation data.
