The independent countertop clean workbench adopts a configuration where the countertop and the air supply main body are supported separately. The tabletop can be installed independently of the air supply box to reduce the transmission of fan vibration to the tabletop. It also makes it easy to adjust the support method according to the weight of the instrument, operating height and maintenance space. Aili Industrial configures the table structure, support method, filtration system and control functions according to the workpiece size, instrument requirements, air flow direction and site conditions. It is suitable for precision detection, optical inspection and instrument supporting clean workstations.

Size, structure and function customization |
The tabletop and air supply box are supported separately, and the fan and filter are installed on the main structure. The tabletop can be independently fixed or equipped with vibration-absorbing supports. This structure helps reduce the impact of fan operation vibration on precision instruments and detection operations.
The table support method can be confirmed according to the weight of the instrument, operating height and on-site ground conditions. The independent countertop also facilitates equipment maintenance to reduce interference with countertop instruments. Clean workbench classification and structural form can be viewed Clean Workbench Learn about different models.
The independent tabletop model can select the airflow direction according to the workpiece shape and operation method. The horizontal flow passes through the work area from the rear to the front, which is suitable for workpieces with a relatively open windward surface; the vertical flow supplies air downward from the top, which is suitable for table operations and situations where the height of the workpiece is low.
The selection of airflow direction needs to be confirmed by combining workpiece shielding, instrument height and operating actions. The structural differences between the two airflows can be referred to How to choose between horizontal flow and vertical flow clean workbench? learn.
The table load needs to be checked based on the weight of the instrument, fixture and workpiece. For heavier instruments, the support position, table thickness and local reinforcement methods should be confirmed. The independent support structure can directly transfer the weight of the instrument to the ground or an independent stand, reducing the impact on the air supply body.
The table top can be equipped with cable holes, instrument fixing interfaces and accessory installation locations. When precision instruments need to be installed, fixing methods, leveling requirements and vibration control measures can be communicated.
Precision inspection stations usually require the connection of multiple cables, including power, signal and ground. The independent table structure can reserve cable channels and fixed positions to reduce the interference of cables on the operating area and airflow.
Cable layout should avoid crossing the air supply surface or affecting the cleaning of the countertop. If necessary, the wiring trough, socket location and interface form can be confirmed during the structural design stage.
Match the fan, motor and air duct according to the air supply area, filter resistance and target wind speed, taking into account the effective working area and operation adjustment requirements.
Filter selection needs to jointly clarify efficiency, size, installation sealing and replacement methods. Related configurations can be found HEPA and ULPA filters , select supporting products based on particle control requirements and system resistance.
After the air is initially filtered, it is sent to the filtration system by the fan, and then enters the work area through the final high-efficiency filter. The horizontal flow model supplies air from the rear to the front, while the vertical flow model supplies air downward from the top. The airflow passes through the operating area and is discharged along the designed path.
Air enters→primary filter→fan air supply→end high-efficiency filter→work area air supply→air discharge
The countertop is independently supported, and the connection method between the air supply body and the countertop needs to confirm the sealing and airflow boundaries. Personnel movements, instruments and larger workpieces may change the local airflow. The performance of the work area should be checked based on the actual placement and working status.

Clean benches are mainly used for product protection and do not provide the personnel and environmental protection that biological safety cabinets have. When infectious materials, toxic volatiles, or other hazardous materials are involved, equipment should be selected based on the risk.
When the workstation needs to place precision instruments, is sensitive to vibration, or the instrument needs independent support, an independent table structure can be evaluated. If the instrument is lightweight or the vibration requirements are not high, you can also choose a conventional integrated workbench.
The instrument weight, support position and allowable vibration range should be clearly defined. The independent support can transfer the weight of the instrument directly to the ground, and the vibration reduction measures can be further evaluated according to the instrument requirements.
After the countertop is independently supported, the connection between the countertop and the air supply body should be kept sealed to prevent unfiltered air from entering the work area from the gap. Connections and airflow boundaries should be checked after installation.
Clean the countertop, side enclosures and operating area according to process requirements to avoid residues affecting subsequent operations. When cleaning, pay attention to the sealing state of the connection between the tabletop and the air supply body.
Regularly check the independent support, vibration reduction device and instrument fixation status. Maintain the primary filter according to the usage environment, and determine the maintenance needs of the terminal filter based on pressure difference, operating wind speed, cleanliness testing and filter status. After replacement, the installation seal and related performance should be rechecked.
Aili Industrial has a manufacturing base of approximately 30,000 square meters, covering R&D and manufacturing links such as motors, fans, control systems, sheet metal, air filters, and complete machine assembly.
For independent countertop clean workbench projects, the table support, vibration reduction structure, instrument interface, filter area, fan operating point and control function can be checked together to support product selection, non-standard design and batch project matching.

The main difference lies in the support method of the tabletop and the air supply body. The independent table supports the table and the air supply box separately, which can reduce the transmission of fan vibration to the table and is suitable for precision testing and instrument supporting work stations.
Independent supports and damping measures can help reduce vibration transmission, but the effectiveness depends on instrument requirements, support methods and site conditions. It needs to be confirmed with the allowable vibration range of the instrument.
It is necessary to check the table load based on the instrument weight, support position and concentrated load, and add independent supports or strengthen structures if necessary.
The design can be carried out according to the instrument size, operating height, interface requirements and on-site space, and the support method, vibration reduction requirements and maintenance space can be checked simultaneously.
It should be combined with pressure difference, wind speed, cleanliness detection and filter status judgment. Recheck sealing and related performance after replacement.
Clarifying instrument size, weight, vibration requirements, airflow direction, and cleanliness goals will help determine an independent tabletop workstation configuration suitable for the actual process.
