Why are high-efficiency filters with partitions suitable for large air volume air filtration systems?

In clean room, HVAC and industrial air treatment projects, if the system needs to handle a larger volume of air, the effective filtration area, structure, face velocity and resistance of the filter will all affect product selection.

The high-efficiency filter with partitions uses partitions to support the pleated filter material to maintain a certain distance between adjacent filter pleats and form a filter channel for air to pass through.

Therefore, when designing a large air volume filtration system, the configuration can be made accordingly according to the filter size, filter material area and system operating conditions.

Things to note are:

Having a baffle structure does not mean that the filter is suitable for all large air volume systems.

The final air volume still needs to be determined based on the specific model and test parameters.

1. How does a high-efficiency filter with partitions achieve air filtration?

After the air enters the filter, the particles are intercepted by the filter material.

Its basic process can be understood as:

Air enters → passes through the filter material → particles are filtered → clean air is output

The function of the partition structure is to maintain a stable spacing between the pleated filter materials.

The structure can be expressed as:

Filter media → folded → separated by partitions → formed filter channels → air passes through

The partition is not directly responsible for filtration, but mainly plays the role of supporting the filter material and maintaining the distance between the filter pleats .

2. Why does the filter area affect the filter air volume?

The filter needs to allow a certain amount of air to pass through the filter material.

Under other similar conditions, the filter area is related to the surface wind speed of air passing through the filter material.

It can be simply understood as:

The filtration area increases → the air volume passing through the unit area can be reduced → which is beneficial to the air volume configuration of the system

But this does not mean that simply increasing the filter area can increase the air volume infinitely.

Actual air volume is also affected by:

filter area

face wind speed

Filtration efficiency

system resistance

Filter material expansion area

The speed of air passing through the filter surface

H13/H14 etc.

Pa

filter size

Filter material structure

System air volume

Fan capacity

W×H×D

There are partitions etc.

m³/h

Determine according to the system

Therefore, these parameters need to be considered together when selecting a high air volume filter.

3. Is the partition structure suitable for large air volume filters?

It can be used in corresponding large air volume air filtration systems, but the specific air volume needs to be determined according to the product model.

The high-efficiency filter with partitions uses partitions to maintain the pleat distance of the filter material, and can be configured with a larger expansion area of ​​the filter material within a certain size range.

For projects with large air treatment capacity, the following can be used:

System air volume → filter size → filter material area → surface air velocity → resistance

Perform product matching.

If the project requires high air volume, structures such as V-type high-efficiency filters can be further considered .

4. What parameters should we pay attention to for large air volume high-efficiency filters?

When purchasing a large air volume high-efficiency filter, it is not recommended to only ask:

'Can this filter be used for large air volume?'

A more accurate way is to provide the specific parameters of the system.

System air volume

Filtration efficiency

filter size

initial resistance

m³/h

H13/H14 etc.

W×H×D

Pa

face wind speed

Filter area

Usage environment

Fan conditions

m/s

Determine based on structure

Clean room/HVAC, etc.

Determine according to the system

Together, these parameters determine whether a filter is suitable for your current air handling system.

5. Why can’t the air volume be judged only based on the filter size?

For example, just because two filters have the same dimensions doesn't mean they have the same airflow rating.

Because the filter also involves:

Filter material type → filter pleat structure → effective filtration area → filtration efficiency → surface wind speed → resistance

If one of these parameters changes, the air volume and resistance performance of the product may also differ.

Therefore, engineering projects should be based on the technical parameters and test data of specific models .

6. How to choose between high-efficiency filter with partition and V-type high-efficiency filter?

If the project requires a larger air handling capacity, you can compare the partitioned structure with the V-shaped structure.

High efficiency filter with partition

V type high efficiency filter

Use partitions to support filter media

Multiple sets of filter elements form a V-shaped structure

Traditional partitioned structure

Suitable for increasing filter media expansion area

Can be used with a variety of air filtration systems

Commonly used for air treatment with larger air volume

Determine air volume based on size and product configuration

Determine air volume based on V-shaped structure and product parameters

There is no simple substitution relationship between the two products.

If the equipment adopts a traditional high-efficiency filter installation structure, partition products can be considered; if the system space and air volume conditions are suitable for a V-shaped structure, you can further select a V-shaped filter.

7. Should I choose H13 or H14 for a large air volume system?

You cannot decide whether to choose H13 or H14 simply based on 'large air volume'.

H13 and H14 belong to different filtration efficiency levels, and the specific selection should be determined based on the project's cleanliness requirements, system design and relevant standards .

For example:

Project requirements

Selection considerations

Common high-efficiency filtration requirements

Choose the appropriate grade according to the design

Higher cleanliness requirements

Confirm efficiency levels such as H13/H14

High cleanliness applications such as semiconductors

Choose according to cleanliness level and equipment requirements

Special cleaning requirements

Further evaluation of ULPA if necessary

Also need to consider:

Filtration efficiency increases → System resistance may change → Fan margin needs to be rechecked

Therefore, we cannot just look at filtration efficiency as a parameter.

8. Can high-efficiency filters with partitions be used in HVAC systems?

Can.

Baffled high-efficiency filters can be used in HVAC air handling systems based on system design requirements.

In HVAC applications, there are often important considerations:

System air volume → filter size → filtration efficiency → initial resistance → fan margin

For equipment such as air conditioning boxes and air handling units that require large air handling capacity, high-efficiency filters with different structures can also be considered based on the internal space and air volume requirements of the equipment.

For example:

HVAC applications

Key parameters

air conditioning box

Air volume, filtration efficiency, resistance

air handling unit

Filter size, air volume

Clean air conditioning system

Filtration efficiency and cleanliness requirements

Industrial air treatment

Air volume, environmental conditions, filter structure

9. Can high-efficiency filters with partitions be used in clean rooms?

Can.

Clean room air filtration systems usually need to select corresponding filtration efficiency and filter structure according to the cleanliness level.

High-efficiency filters with partitions can be used in some clean room air filtration systems. The specific application location needs to be determined according to the clean room design.

For example:

Fresh air treatment → Air conditioning box filtration → Clean air conditioning → Terminal high efficiency filtration

Filtering requirements are not exactly the same across locations.

Therefore, clean room projects should configure filters based on the overall air handling system, rather than just selecting a certain device.

13. Basic logic for selecting high-efficiency filters with large air volume

The actual project can be carried out according to the following process:

Confirm system air volume → Confirm filtration efficiency → Confirm installation space → Confirm filter structure → Check resistance → Confirm product specifications

If system space is limited, filter thickness will also need to be focused on.

If the system air volume is large, you need to focus on the filter area, face velocity and resistance.

If the cleanliness requirements are higher, the HEPA or ULPA grade needs to be further confirmed.

14. Aili industrial high-efficiency filter solution

High-efficiency filters are not products that can be selected simply by looking at one parameter.
