High-efficiency air supply outlets are usually installed on the ceiling of clean rooms as the end air supply equipment of centralized air treatment systems.
During installation, not only do you need to fix the box to the ceiling, but you also need to handle:
Site dimensions → Ceiling opening → Box fixing → Air duct connection → Sealing → Internal cleaning → HEPA/ULPA filter installation → System debugging
Among them, size matching, interface sealing, installation cleanliness and filter protection are several aspects that need to be focused on during the installation process.
Relevant clean room construction requirements also emphasize that the size of the air outlet of the high-efficiency filter should meet the design requirements and should be cleaned before installation. The joint between the air outlet and the ceiling needs to be sealed. After the air outlet is installed, it should be connected to the air duct in time and the opening should be protected.
The common installation process of high-efficiency air supply vents can be summarized as:
On-site confirmation → Dimension check → Ceiling opening → Box hoisting → Horizontal adjustment → Box fixing → Air duct connection → Seam sealing → Box cleaning → HEPA/ULPA filter installation → Inspection and debugging
In actual projects, the specific construction sequence needs to be determined based on the clean room structure, air supply outlet structure and construction organization arrangements.
Before installation, you first need to confirm the location of the air supply outlet according to the clean room design drawings.

It is not possible to directly drill holes for installation without confirming the on-site dimensions.
The size of the high-efficiency air supply vent box, filter size and ceiling opening size need to match each other.
It is recommended to check before installation:
Overall size of air supply outlet + installation size + ceiling module size + filter size + air duct interface size
If customized products are used, further verification is required:
Box length, width and height
Flange size
Top air inlet interface
Side air inlet interface
filter size
Installation hole position
boom position
Relevant construction information also requires that the size of the air supply outlet of the high-efficiency filter meets the design requirements.
A visual inspection should be done first.

according toof the high-efficiency air supply outlet is determined on the clean room ceiling panel.The actual installation size
The typical process is:
Measure → Position → Mark → Open → Clean the opening → Check size
Special attention is needed here:
Don't simply drill holes according to a certain fixed amount.
There may be size differences in different ceiling systems, air outlet structures and installation methods. The actual product installation dimensions and project construction drawings should prevail.
Install the high-efficiency air supply box to the ceiling opening.
It can usually be installed using booms, hangers, or fixed structures designed for the project.
Need to adjust during installation:
Cabinet height → Level → Flange position → Ceiling plane
Generally, it is necessary to make the lower edge of the air supply port and the clean room ceiling form a reasonable match.
Do not allow the filter or box to bear unreasonable structural loads during installation.
After the box is fixed, connect the air duct according to the air inlet structure.
Typical connection method:
Main air duct → Branch air duct → Top interface → High-efficiency air supply outlet
Typical connection method:
Main air duct → Branch air duct → Side interface → High-efficiency air supply outlet
The specific connection form needs to be determined according to the circular interface, square flange interface or other structures.
After the connection is completed, you need to check:
Whether the interface matches
Is the fixation firm?
Is the seal continuous?
Is there any obvious risk of air leakage?
Does the air duct produce additional pulling force on the box?
The clean room construction requirements also emphasize that the air supply outlet should be connected to the air duct after installation, and the opening should be protected and sealed.
When installing high-efficiency air supply vents, the joint between the box and the clean room ceiling is a location that needs to be focused.
The typical structure can be understood as:
Air supply flange→Sealing material→Clean room ceiling panel
The purpose of sealing is to reduce the possibility of untreated air bypassing the installation gap and entering the clean room.
Therefore, after installation you need to check:
Flange joint → surrounding seal → interface seal → ceiling panel connection
If obvious gaps are found, they should be processed according to the project construction requirements.
Relevant specification information also clearly states that the joint between the air outlet flange and the ceiling panel needs to be sealed.
The sooner a high-efficiency filter is installed, the better.
During the clean room construction process, efforts should be made to avoid prolonged exposure of the filter to the dust environment.
Before installing the filter, you need to confirm:

HEPA and ULPA filters are precision filtration components and should be avoided during installation:
impact
extrusion
Scratched filter media
Disassemble at will
prolonged exposure
Construction that generates large amounts of dust is carried out near the filter
Filter transportation and storage should also be carried out in accordance with the manufacturer's requirements to avoid severe vibration and collision.
After the installation is completed, it is not recommended to just check 'whether the air vent is installed'.
Systematic installation checks should be carried out.
You can follow:
Appearance inspection → Box inspection → Air duct inspection → Seal inspection → Filter inspection → Air volume debugging → System inspection → Cleanliness verification
conduct.
Specific testing items and acceptance standards should be based on project design documents, contract technical requirements and applicable standards.
Typical air path:
Air duct → Top air inlet interface → Static pressure box → HEPA/ULPA → Clean room
Focus on:
Head space + duct height + ceiling height + maintenance space
Typical air path:
Air duct → Side air inlet interface → Static pressure box → HEPA/ULPA → Clean room
Focus on:
Side air duct position + interface space + ceiling structure + maintenance space
Therefore, although the basic process of the installation method is similar, the interface direction and on-site size confirmation are different.
