The side air inlet high-efficiency air supply port refers to in which the air inlet interface is set on the side of the box .a high-efficiency air supply port structure
The air enters the air supply port from the side duct, then passes through the internal static pressure box and HEPA/ULPA filter, and finally enters the clean room through the diffuser device.
Typical air paths are:
Air conditioning box/air treatment equipment → Air duct → Side air inlet interface → Static pressure box → HEPA/ULPA filter → Clean room
The biggest structural difference between it and the top-inlet high-efficiency air supply vent is that the air duct connection direction is different.
Side-intake high-efficiency air supply vents are usually suitable for projects where the air duct needs to be connected from the side of the air supply vent, or where the top space is not convenient for direct connection of the air duct .

The basic air flow is:
Side air duct → Side air inlet interface → Static plenum → High efficiency filter → Diffusion panel → Clean room
The side air intake structure can be considered in the following situations.
If the air duct passes by the side of the air supply outlet, you can use the side interface to connect it.
Side-intake can be a structural option when headspace is limited by beams, piping, or other equipment.
For renovation projects, if the direction of the original air duct has been determined and the air duct cannot be easily accessed from the top, side air inlet can be selected based on site conditions.
When there are multiple systems such as fire protection, lighting, and process pipelines above the suspended ceiling, the air inlet direction can be selected based on the on-site space.
It should be noted that side air inlet does not mean that the air duct resistance and airflow organization can be ignored. System design and verification are still required in the end.
It can be considered based on specific site conditions.
Compared with new construction projects, clean room renovation projects are usually affected by the following:
air duct
Liang
suspended ceiling
pipeline
equipment
Inspection space
and other conditions.
If the original air duct is more convenient to access from the side, the side air inlet high-efficiency air supply outlet can be used as an end structure option.
Typical transformation ideas are:
Original air duct → On-site interface confirmation → Side air inlet high-efficiency air supply outlet → HEPA/ULPA → Clean room
However, whether it can be directly replaced requires measuring the on-site dimensions and confirming the air volume, static pressure and filter specifications of the original system.
Both structures can be used for air supply at the end of the clean room. The main difference is the location of the air inlet interface.

The selection method can be simply understood as:
Where does the air duct come from → The air supply outlet is selected according to the on-site conditions to correspond to the air inlet direction.
The air supply effect cannot be judged based only on the three words 'side air intake'.
Actual terminal air conditions depend on several factors, including:
Design air volume
Duct resistance
Static pressure box structure
filter resistance
Filter installation
diffuser
Air outlet layout
Return air method
Overall airflow organization
Therefore, the side-intake high-efficiency air supply vents need to be selected and matched to the system according to the designed air volume.
Its basic design logic is:
Design air volume → Air duct system → Side air inlet interface → Static pressure box → Filter → Air supply surface → Clean room
There is no fixed size of installation space that applies to all products.
Need to be based on:
Cabinet size + side interface size + duct size + filter size + maintenance space
Make sure.
Especially in clean rooms with tight ceiling spaces, measurements should be made in advance:
Ceiling height
Duct height
Duct width
side distance
Beam and column position
Other pipelines
Filter maintenance space
This can reduce structural conflicts during later installation.
There is no direct correspondence between the side air inlet structure and the filter grade.
Filters should be selected based on clean room design requirements.
Common configurations include:
HEPA
ULPA
When choosing, you need to consider comprehensively:
Cleanliness level → Filtration efficiency → Design air volume → Filter size → Filter resistance → Filter maintenance
If the filter model has been determined, the air supply box, filter installation structure and sealing method need to match it.
Side air inlet is the same as top air inlet. The design air volume of a single air outlet needs to be determined based on the overall design of the clean room.
For example:
The total designed air supply volume of the clean room is 6000m³/h.
If the design air volume of a single side-inlet high-efficiency air supply outlet is 500m³/h:
6000 ÷ 500 = 12
This is a theoretical quantity.
In practice, it is also necessary to combine:
Air outlet position
Ceiling size
Device location
Return air position
airflow organization
filter resistance
Duct system resistance
Make adjustments.
It is recommended to organize the following parameters when purchasing projects:

It can be judged based on the actual structure.
If the top space is not enough to facilitate the arrangement of top air ducts and interfaces, and there is available air duct installation space on the side, a side air inlet structure can be considered.
But please note:
Low ceiling ≠ must use side air intake
Ultimately it is still necessary to measure the on-site space and compare the installation conditions of different air inlet structures.
Side air intakeHigh-efficiency air supply vents can be used in centralized duct air supply systems.
A typical system is:
Air treatment equipment → Main air duct → Branch air duct → Side air inlet high-efficiency air supply outlet → HEPA/ULPA → Clean room
If the project adopts a modular air treatment method, equipment such as FFU and EFU can be considered according to the specific area.
Therefore, when selecting equipment, you first need to clarify which air treatment method is used in the clean room.
Aili Industrial can match the structure and specifications of the side-intake high-efficiency air supply vents based on the site conditions of the clean room project.
Key points to confirm:
Air duct position → Side interface → Design air volume → HEPA/ULPA filter → Box size → Ceiling size → Maintenance space
If the project is a clean room renovation, the air inlet method can also be determined based on the original air ducts, ceilings and equipment locations on site.
Aili Industry itself has the manufacturing capabilities of sheet metal, filters, fans, motors and control systems, and also provides high-efficiency filters, FFU, EFU and other clean air treatment equipment.
For different clean areas, product combinations can be made based on the actual needs of centralized air supply, modular air supply and equipment-side air supply.
It is mainly suitable for clean room projects where the air duct needs to be connected from the side, the top space is limited, or the on-site air duct has been arranged laterally.
Can. For renovation projects, the side air inlet structure can be selected based on the original air duct location and on-site space.
The two are mainly different in the direction of air inlet, and there is no unified applicable conclusion. The selection should be based on the direction of the air duct, ceiling space, installation conditions and maintenance methods.
HEPA filters can be configured according to the project design, and the specific needs are to match the filter specifications, air volume and box structure.
Selection can be made based on the overall design of the ISO 5 clean room. Whether to use side air inlet needs to be determined based on the air duct layout, design air volume, air flow organization and filter configuration.
It is necessary to first determine the total design air supply volume of the clean room, and then configure it according to the number of air outlets, the air volume of a single air outlet and the air flow organization.
Side air intakeThe main feature of the high-efficiency air supply vent is that the air inlet interface is located on the side of the box , which is suitable for projects where the air duct needs to be connected horizontally, the top space is limited, or the on-site pipeline layout requires access from the side.
When selecting, it is recommended to follow:
On-site air duct → Air inlet direction → Ceiling space → Design air volume → HEPA/ULPA → Air outlet size → Installation and maintenance
Make comprehensive judgments.
For new projects, the air inlet direction can be determined during the clean room design stage; for renovation projects, the original air duct and ceiling space should be measured first, and then the top air inlet or side air inlet structure should be selected.
