What are the main parameters to consider when selecting a high-efficiency air outlet?

When selecting an efficient air supply outlet , you usually need to focus on the following parameters:

Design air volume, filter grade, filter size, box size, system static pressure, air inlet method, ceiling size, installation height, maintenance space and sealing structure.

The most core parameters can be summarized as:

The air volume determines how much air is sent, the filter determines the filtration configuration, the size determines whether it can be installed, the static pressure determines whether the system matches, and the air inlet method determines how to connect the air duct.

Therefore, when purchasing high-efficiency air supply vents, you should not just ask:

'How much does this air outlet cost?'

You should first determine:

'Does the air volume, filter, size and interface of this air supply vent match my clean room system?'

4. The first core parameter: design air volume

Design air volume is an important parameter for selecting efficient air supply vents.

The efficient air supply outlet ultimately needs to meet the end air supply needs of the clean room, so it needs to be determined first:

Total air supply volume of clean room

Then according to:

Total air supply volume ÷ number of air supply outlets

Obtain the average design air volume of a single air supply outlet.

For example:

Total air supply volume 6000m³/h ÷ 12 air supply outlets = 500m³/h/each

Then a single air supply outlet can use approximately 500m³/h as a preliminary selection reference.

The actual product also needs to be combined with:

Filter resistance + system static pressure + air flow organization + air supply speed

to confirm.

5. The second core parameter: filter level

High-efficiency air supply vents are usually equipped with HEPA or ULPA filters.

Common filtering levels include:

H13, H14, U15, U16, U17

Things to consider when choosing:

• Cleanliness level

• Process requirements

• target particle size

• Filtration efficiency

• filter resistance

• Project acceptance requirements

therefore:

The filter grade should be determined based on actual cleanliness requirements, rather than simply assuming that a higher grade is more suitable for all projects.

6. The third core parameter: filter size

The size of the filter directly affects the structure of the air supply box.

Need to confirm:

Length × Width × Thickness

as well as:

Installation frame size + sealing structure + compression method

For example, HEPA filters of different sizes will have different sizes of matching air outlet boxes.

Therefore, it is best to provide:

Filter specifications + air outlet dimensions + ceiling opening dimensions

Avoid size mismatches on site.

7. The fourth core parameter: air outlet box size

Common requirements for high-efficiency air supply vents include:

Length×width×height

in:

length and width

Main impact:

• ceiling module

• filter size

• Opening size

high

Main impact:

• Space above suspended ceiling

• Static plenum space

• Duct connection

• Filter maintenance

If the height of the technical mezzanine is relatively limited, the height of the cabinet needs to be confirmed carefully.

8. The fifth core parameter: system static pressure

High-efficiency air supply vents are part of the overall air handling system.

Typical system:

MAU/AHU → Main air duct → Branch air duct → High-efficiency air supply outlet → HEPA/ULPA → Clean room

Therefore, the air supply outlet selection needs to match the system static pressure.

Need to consider:

Duct resistance + air supply outlet resistance + filter resistance + other system resistance

If the system static pressure is insufficient, the design air volume may not be achieved.

therefore:

High-efficiency air supply outlets cannot determine the air volume independently of the entire air duct system.

9. The sixth core parameter: air intake method

Mainly divided into:

Head into the wind

and

Side air intake

Head into the wind

Air duct → Top interface → Static pressure box → HEPA/ULPA → Clean room

Suitable for air ducts connected from the top.

Side air intake

Air duct → Side interface → Static pressure box → HEPA/ULPA → Clean room

Suitable for air ducts connected from the side.

The main basis for selection is:

Air duct location + ceiling structure + technical mezzanine space

Sure.

10. The seventh core parameter: ceiling size

If the high-efficiency air supply vent is installed on the clean room ceiling, the ceiling module must be confirmed.

Need to check:

Ceiling board size → Air supply outlet size → Opening size → Fixing method

Especially for modular clean rooms, the air supply vents and ceiling panels need to be matched in size.

11. The eighth core parameter: installation height

The installation height mainly includes:

Cabinet height + ceiling space + air duct connection space

If the technical mezzanine height is relatively small, you need to focus on:

• Cabinet height

• Duct height

• Filter replacement space

• Inspection space

• Electrical or other pipelines

12. The ninth core parameter: maintenance space

After the high-efficiency air supply vent is installed, the HEPA or ULPA filter needs to be maintained and replaced.

Therefore, you need to confirm in advance:

Filter disassembly and assembly direction + maintenance space + inspection channel

If a structure is used for maintenance from below, it is necessary to confirm whether there is sufficient operating space inside the clean room.

If maintenance is performed from above, it is necessary to confirm whether the technical mezzanine above the suspended ceiling can be operated.

13. The tenth core parameter: sealed structure

Sealing needs to be considered between the high-efficiency air supply outlet and the clean room ceiling, and between the filter and the installation frame.

Need attention:

• Box flange

• sealing material

• Filter sealing structure

• compression structure

• Ceiling seams

During model selection, if the project has high sealing requirements, the sealing structure and installation method of the product should be confirmed in advance.

14. How to classify the parameters of high-efficiency air supply outlets?

From a procurement and engineering perspective, parameters can be divided into five categories:

This makes it easier to judge whether the product is suitable for the project than simply looking at a product parameter table.

15. How do the high-efficiency air supply outlet parameters correspond to the clean room parameters?

Matching can be performed according to the following logic:

16. Which parameter of the high-efficiency air supply outlet is the most important?

It cannot simply be said that only one is most important.

For actual projects, it is recommended to give priority to:

① Design air volume

② Filter level

③ Filter size

④ Air outlet size

⑤ System static pressure

⑥ Air intake method

⑦ Ceiling size

⑧ Maintenance space

These parameters are related to each other.

For example:

Air volume → affects filter and air outlet selection

Filter size → affects box size

Box size → affects ceiling and installation space

The position of the air duct → affects the top air inlet/side air inlet

Therefore, comprehensive selection is still required in the end.

17. What should be included in the high-efficiency air supply parameter table?

If the manufacturer produces a product parameter sheet, it is recommended to include at least:

18. How to determine the parameters of Aili industrial high-efficiency air supply outlet?
