How to install high-efficiency air supply vents?

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.

4. The complete process of installing efficient air supply vents

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.

5. Step 1: Confirm the installation location of the efficient air supply outlet

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.

6. Step 2: Check the size of the efficient air supply outlet

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.

Reconfirm before installation

If the cabinet has been significantly deformed or the interface is damaged, it should be processed first and should not be installed directly.

8. Step 4: Prepare the ceiling installation opening

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.

9. Step 5: Lift and fix the air outlet box

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.

10. Step 6: Connect the air duct

After the box is fixed, connect the air duct according to the air inlet structure.

Top air intake structure

Typical connection method:

Main air duct → Branch air duct → Top interface → High-efficiency air supply outlet

Side air inlet structure

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.

11. Step 7: Make a good seal between the box and the ceiling

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.

12. Step 8: Install HEPA or ULPA filter

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:
