On the basis of filtered air supply, the anti-static clean workbench is equipped with an electrostatic dissipation table, a grounding system and related electrostatic control measures to provide a clean operating environment for electrostatically sensitive electronic devices. Aili Industrial configures the table material, grounding structure, filtration system and control function according to the sensitivity of the device, fixture material, personnel grounding method and cleanliness target, so that cleanliness protection and static electricity control can be coordinated in the same work station.

Work surfaces can be made of static-dissipative materials that guide static charges to the ground through a grounding system. The table surface resistance and grounding resistance must be confirmed according to project requirements and verified through testing.
The grounding structure includes table grounding, personnel grounding and tooling grounding. The three should confirm the connection method and detection point respectively to avoid only grounding the tabletop and ignoring personnel or work equipment. Clean workbench classification and structural form can be viewed Clean Workbench Learn about different models.
The anti-static clean workbench 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 based on workpiece occlusion, operating actions and background conditions. The structural differences between the two airflows can be referred to How to choose between horizontal flow and vertical flow clean workbench? learn.
Particle control and static control in clean environments need to be considered simultaneously. Some anti-static materials may produce particles, and certain cleaning methods may affect the resistance of the countertop. Both should be checked together when selecting.
Personnel grounding, anti-static clothing, ionization equipment and operating procedures also affect workstation static levels and should be confirmed together with clean operating procedures.
The load capacity of the tabletop needs to be checked based on the weight of the workpiece, fixture and instrument. For heavier concentrated loads, the support position and local reinforcement method should be confirmed. The tabletop can be equipped with threading holes, tooling fixing positions and accessory interfaces as required.
When it is necessary to install tooling or supporting equipment, the fixed hole positions, threading positions and accessory interfaces can be communicated. The countertop material, thickness and support spacing can be confirmed according to project requirements.
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 supply→end high-efficiency filter→work area air supply→air discharge
Static control is achieved through grounding of countertops, personnel, and work equipment. During operation, human movements, tools 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 handling of non-hazardous materials |
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.
Different devices have different sensitivity to static electricity. The device withstand voltage, operating environment and protection level should be confirmed. Determine the table resistance, grounding method and personnel protection measures according to the degree of sensitivity.
The connection methods and detection points for table grounding, personnel grounding and tooling grounding should be confirmed respectively. The grounding system needs to be tested regularly to ensure reliable connections.
Anti-static materials may produce particles or affect cleaning methods. Cleaning requirements and static electricity control should be confirmed together when selecting. Certain cleaners may affect countertop resistance and compatibility should be confirmed.
Space needs to be reserved for air inlet, filter replacement and fan maintenance at the rear of the equipment. When installing against a wall or side by side, make sure that the maintenance channel can be opened normally.
Clean the countertop, side enclosures and operating area according to process requirements to avoid residues affecting subsequent operations. After cleaning, the resistance and grounding status of the table should be confirmed.
Regularly check ground connections, table resistance, and personnel grounds. 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 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 anti-static clean workbench projects, the table material, grounding structure, support frame, 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 differences are in the countertop material and grounding configuration. The anti-static workbench is equipped with a static dissipative tabletop and grounding system, which is suitable for the operation of electrostatic-sensitive devices.
no. The connection methods and detection points need to be confirmed separately for table grounding, personnel grounding and tooling grounding. The three together constitute workstation static electricity control.
Both material particle release and cleaning methods need to be confirmed. Compatibility of anti-static materials with cleanliness requirements should be checked during the selection stage.
It should be confirmed based on the sensitivity of the device and the mode of operation. Personnel grounding and work equipment grounding also affect the level of static electricity at the workstation, and it is recommended to evaluate them together.
It should be combined with pressure difference, wind speed, cleanliness detection and filter status judgment. Recheck sealing and related performance after replacement.
Clarifying device sensitivity, static control requirements, workpiece size, airflow direction and cleaning goals will help determine the anti-static work station configuration suitable for the actual process.
