How to consider increasing air volume in the future when selecting ULPA filters?

When selecting a ULPA filter to consider increasing air volume in the future, the current and expanded working conditions should be listed separately, and the capacity range of the filter element, fan, interface and air supply distribution should be checked. Existing ratings cannot be extrapolated arbitrarily. A common way to reserve expansion is to 'select a larger size', but 'sizing up' solves the current margin, but does not solve future path problems: how much air volume to increase, how to increase it, whether the fan and ducts can still hold up after the increase, and whether the interface is still compatible. If you don't think clearly about these, no matter how large the margin is, you may not be able to use it. Aili Industry isWhen selecting HEPA/ULPA filters , check the filter area, fan working point and interface configuration according to the current working conditions and extended working conditions.FFU fan filter unit andThe speed adjustment capability of the fan filter unit on the EFU equipment side reserves operating space for air volume adjustment, allowing expansion planning to have a specific and executable product path.

1. Clarify expansion goals: how much to add, where to add, and when to add

Explain how much air volume will be increased, in which areas, how long it will run, and whether the process protection objectives have changed. Avoid just proposing 'reserve some margin'.

'Reserve margin' is not a goal, but a means. The real expansion goal should be specific: the proportion of air volume increase, the location of the increase (whether it is a new area or an existing area to increase the wind speed), the expected time node, and whether the process protection requirements will change after the increase. Different expansion goals correspond to different reservation methods: if the air volume is increased in an existing area, it depends on the fan margin and pipeline capacity; if it is a new area, it depends on the system expansion interface and total air volume distribution. Aili Industry isULPA ultra-high-efficiency filter selection communication, the specific content of the expansion target will be confirmed first, and then the reservation plan will be evaluated. During the The relationship between grade and air supply requirements can be referred toISO cleanliness level comparison。

2. Choose an achievable expansion path: add modules, add area or fan

Compare the options of adding modules, increasing area, adjusting fans and air ducts, and also check the power supply, control and maintenance space.

There are three basic paths to expand the air volume: increasing the number of modules, increasing the filter area of ​​a single unit, and increasing the operating air volume of existing modules. The three paths have different costs. Adding modules requires room for arrangement on the ceiling or box, and the power supply and group control points must also be increased accordingly; increasing the area of ​​a single unit requires installation space to allow for larger-sized filters; increasing operating air volume requires fans to have margin and pipe resistance not to exceed standards. Aili Industry isNon-standard ULPA filters andIn the FFU fan filter unit expansion project, the feasibility of three paths is evaluated based on the actual project conditions.Tank seal ULPA filter andThe structural dimensions of the partition-less ULPA ultra-high-efficiency filter can be used as the basis for increasing the area. For comparison methods of expansion paths, please refer toHEPA FAQs and Selection Guide。

3. Phased verification of working conditions: The current plan is currently applicable and will be reconfirmed after expansion.

The current solution should be applicable at this stage, and the operating point, uniformity and related performance need to be re-confirmed after expansion. The reserved interface should also have clear dimensions and closed status.

Reserved expansion does not mean that it can be run according to the expanded operating conditions currently. The current selection should confirm the operating point and performance according to the current working conditions, and then reconfirm according to the new working conditions after expansion. If the current model is selected based on the extended working conditions, there may be problems with the equipment operating in the low-efficiency zone for a long time and energy consumption being high. Aili Industry isIn the expansion plan of the FFU fan filter unit , the operating parameters are set according to the current air volume in the current stage. During expansion, the new operating conditions are reached by adjusting the speed or adding modules.The FFU computer group control system records the operating parameters of each stage for easy comparison. For the handling method of reserved interfaces, please refer toULPA ultra-high efficiency filter FAQ and selection guide。

4. When planning to expand the production line, adding new modules may be more appropriate than allowing the original filter element to operate beyond its rated capacity.

When planning to expand a production line, adding new modules may be more appropriate than running the original filter element beyond its rated capacity, but it needs to be combined with layout calculations. The original filter element operates above the designed air volume, and the surface wind speed and resistance increase. The fan needs to provide greater residual pressure. Long-term over-rated operation will affect the filter life and operational stability.

In the expansion project, Aili Industrial evaluates whether to add modules or expand the original system based on the air volume demand and layout conditions of the new area.The fan filter unit at the EFU equipment end can be configured separately according to the new equipment.Non-standard ULPA filters can be customized according to new regional interfaces. For comparison of expansion plans, please refer toFFU FAQ and technical support。

5. Related questions and answers

Does buying a higher level in advance count as a reserve?
Filtration level and air volume margin are different concepts, and performance and system capabilities need to be checked separately.

Is the larger the reserve margin, the better?
no. Excessive margin will cause the current equipment to operate in the low-efficiency zone for a long time, increasing energy consumption and operating costs. A reasonable margin should be determined based on the actual expansion plan.

What should I pay attention to when reserving interfaces?
The reserved interface should have clear size, location and closed status, so that it can be connected directly during expansion and will not be unusable due to unclear interfaces.
