1. What parts does a high-efficiency air outlet consist of?

The high-efficiency air supply vent is not a single structure, but consists of multiple parts that cooperate with each other.

Common high-efficiency air supply outlets mainly include:

Box → Air inlet interface → Static pressure box → Filter installation structure → HEPA/ULPA filter → Diffusion device → Clean room

The products of different manufacturers, different structural forms and different engineering projects will be different.

For example, some projects require top air inlet, some projects require side air inlet; some projects use detachable filter maintenance, and some projects use other maintenance methods based on on-site technical mezzanine and suspended ceiling structures.

Therefore, the specific structure of the high-efficiency air supply outlet should be determined based on actual engineering conditions.

2. What are the functions of each part of the high-efficiency air outlet?

The main components of an efficient air supply vent can be organized as follows:

These structures are not independent of each other.

For example, the size of the filter will affect the box structure, the filter resistance will affect the required static pressure and air volume, and the air supply surface structure will affect the terminal airflow organization.

Therefore, high-efficiency air supply vents should be designed as a complete end assembly.

3. What is the function of the box?

The box is the main structure of the high-efficiency air supply outlet.

It is mainly used for:

• Fixed internal components

• Connect the air inlet interface

• Install filter

• With ceiling installation

• Form a relatively independent air supply channel

• Provide filter maintenance structure

The size of the box needs to be determined based on the filter size, air volume, installation space and on-site ceiling conditions.

Common materials can be selected according to project requirements, such as spray-coated steel plates, stainless steel, etc.

For clean room projects, it is also necessary to pay attention to whether the surface of the box is easy to clean and whether the structural connection locations are sealed.

4. What is the function of the air inlet interface?

The air inlet interface is the location where the high-efficiency air supply port is connected to the upstream air duct.

Depending on the on-site installation conditions, different air intake methods can be used.

Common ways include:

Top air duct → top air inlet interface → static pressure box → filter → clean room

or:

Side air duct → Side air inlet interface → Static plenum → Filter → Clean room

The specific choice mainly depends on:

Therefore, providing on-site installation conditions before project procurement can help manufacturers more accurately determine the form of the air inlet interface.

5. What is the function of the static pressure box?

The static plenum is an important structure of some high-efficiency air supply vents.

After the air enters from the air duct, it does not directly pass through the filter in the original air flow state, but first enters the static pressure box area.

The static pressure box can provide a certain buffer and distribution space for the air entering the end, making the air more suitable for entering the filter area.

The basic process can be understood as:

High-speed airflow in the air duct → enters the static pressure box → airflow buffering and distribution → passes through the filter → enters the clean room

The specific structure of the static pressure box needs to be designed based on the air supply volume, air inlet method, filter size and product structure.

The following article will specifically introduce 'What is the function of the high-efficiency air supply port static pressure box'.

6. What is the function of the filter installation structure?

The high-efficiency filter needs to be installed inside the air supply outlet, so the high-efficiency air supply outlet must have an installation structure that matches the filter.

The main functions include:

Secures filter → maintains installation position → creates seal → facilitates maintenance

The filter mounting structure needs to match the filter size, sealing method and maintenance method.

For example, when a project uses HEPA or ULPA filters of different specifications, the installation structure inside the air supply outlet also needs to be adjusted accordingly.

7. What does a HEPA/ULPA filter do?

HEPA or ULPA filters are air filtration components in high-efficiency air supply vents.

After the air passes through the filter, it enters the clean room.

Depending on project requirements, different filter efficiency levels can be selected.

Common choices include:

Specific filter ratings cannot be determined independently of cleanroom design requirements.

In addition to efficiency ratings, you also need to consider:

• filter size

• initial resistance

• Rated air volume

• Sealing method

• Installation method

• Later replacement conditions

Therefore, when selecting a high-efficiency air supply outlet, you should also confirm whether the air supply outlet and the filter match.

8. What is the function of the diffuser device?

The diffuser device is located at the air supply end and is used to organize the air supply after passing through the filter.

Its function is not to simply 'let the air out', but to cooperate with the overall air flow organization of the clean room so that the filtered air enters the clean space according to the design requirements.

The specific form needs to be determined according to the clean room design.

For example, different clean rooms may use different supply air, return air and air flow organization methods, so the diffuser structure also needs to match the project plan.

9. Why does a high-efficiency air supply outlet need a sealed structure?

efficient air supply ventsInstallation of After HEPA or ULPA filter , it is necessary to ensure a reliable seal between the filter and the installation structure.

The reason is:

The air should pass through the filter → before entering the clean room

instead of:

Air bypasses the filter → goes directly into the clean room

Therefore, the filter installation structure and sealing method are the parts that need to be focused on in the design of high-efficiency air supply outlets.

In actual projects, a matching sealing solution should be selected based on the filter structure.

10. How does the efficient air supply outlet structure affect the selection?

Different projects have different requirements for efficient air supply vents.

For example:

Clean room ceiling space is limited

It is necessary to focus on the cabinet height, air intake method and maintenance space.

Air duct enters from the side

Consider a side air intake structure.

Filter maintenance needs to be done from the clean room side

It is necessary to confirm the filter disassembly and installation direction and maintenance space in advance.

Use ULPA filter

Filter size, resistance, and supply system static pressure need to be considered.

Therefore, high-efficiency air supply outlets are not simply selected according to 'size', but need to consider the filter, air volume, air inlet method, installation space and maintenance method together.

11. How to match the products of Aili industrial high-efficiency air supply vents?

Aili Industrial provides high-efficiency air supply vents, HEPA/ULPA filters, FFU, EFU and other products in the field of clean air treatment equipment.

For ordinary clean room projects, selection can be made based on conventional filter specifications, air volume and installation methods.

For clean projects such as semiconductors, electronics, photovoltaics, and biomedicine, it can be further combined:

Cleanliness level → Air volume → Filter → Air inlet method → ​​Ceiling structure → Maintenance method

Perform product matching.

Aili Industry itself has production and R&D capabilities for sheet metal, filters, fans, motors and control systems. When a project requires multiple clean air treatment products, it can reduce the communication links caused by separate matching of different equipment.

For example, a cleaning project may involve:

Efficient air supply outlet + HEPA/ULPA filter + FFU + EFU + control system

Model selection can be made based on the actual needs of the project, rather than using the same equipment for all clean areas.

12. Basic judgment method for selecting efficient air supply outlet structure

In actual projects, you can confirm according to the following logic:

Cleanliness level → Air volume → Filter → Air inlet mode → Static pressure box → Installation structure → Maintenance method

in:

• The cleanliness level determines the filter selection direction;

• The air volume affects the air supply outlet specifications and system configuration;

• The filter determines the installation size and resistance conditions;

• The air inlet method is determined by the on-site air duct layout;

• The plenum is related to the organization of the airflow before it enters the filter;

• The installation structure needs to match the suspended ceiling;

• The maintenance method determines whether it is convenient to replace the filter later.

This is also a more practical judgment method when choosing high-efficiency air supply vents.

13. Summary

High-efficiency air supply vents usually consist of:

Cabinet + air inlet interface + static pressure box + filter installation structure + HEPA/ULPA filter + diffuser device + maintenance structure

composed of other parts.

The specific structures of different products will be adjusted according to project needs.

Therefore, when purchasing high-efficiency air outlets, it is not recommended to provide only one 'product size', but should also provide cleanliness level, design air volume, filter level, air duct location, ceiling structure and maintenance requirements.

Aili Industry can design high-efficiency air supply vents andHEPA and ULPA filters are matched and can be combined with clean air treatment equipment such as FFU and EFU to form different clean air supply solutions.
