How to change the filter of the horizontal and vertical flow cabinet?

First, horizontal flow table filter replacement
(1) Preparation
Prepare tools and materials
First, you need to have the right tools, such as a screwdriver, wrench (if there are screws or nuts to hold the filter), and a clean pair of gloves. In order to prevent dust and impurities from entering the workbench, you should also prepare a clean plastic sheet or plastic wrap.
Buy a new filter that matches your workbench model. Ensure that the filter specifications (such as size, filtration efficiency, material, etc.) meet the requirements of the equipment. Refer to the workbench's user manual or contact the manufacturer for accurate filter model information.
Safety measure
Before replacing the filter, be sure to turn off the power to the workbench and unplug it to avoid the risk of electric shock. At the same time, clean the items on the work surface and put them in a safe place.
(2) Find the filter location
Fix position
The filter for the horizontal flow table is usually located at the rear of the table. Some workstations may have a removable rear cover that can be opened by unscrewing or releasing the buckle; Some may install the filter through a drawer or sliding structure.
Look carefully at the design of the workbench and look for signs indicating the installation location of the filter or refer to the instructions in the user manual.
(3) Remove the old filter
unfasten
If the filter is secured by screws, use a screwdriver to carefully remove the screws. Keep the screws well to avoid losing them. If the clip is used, gently press or unclip the clip to release the fastening device of the filter.
During the removal process, be careful to avoid damaging the sealing strip and other components around the filter.
Remove old filter
When the fixture is loosened, slowly remove the old filter from the mounting position. Since a lot of dust and impurities may accumulate on the filter, try to keep it smooth and prevent dust from flying. The filter can be placed in a pre-prepared plastic bag and sealed to reduce dust diffusion.
(4) Install new filters
Checking the installation environment
Before installing a new filter, check that the installation slot or location of the filter is clean. Wipe the installation position with a clean, damp cloth to remove residual dust and impurities. At the same time, check whether the sealing rubber strip is intact, if it is damaged, it should be replaced in time.
Install new filter
Place the new filter into the installation position in the correct direction. Note that the filter is usually marked with the installation direction, such as an arrow indicating the direction of airflow, to ensure that the installation direction is consistent with the airflow direction of the workbench.
For filters with screws in place, reinstall the screws and tighten them, but do not over-tighten them to avoid damaging the filter or mounting frame. For the clamp-type fixed filter, the card QQ is good to ensure that the filter is firmly installed.
(5) Check the installation
Tightness check
After installation, check the tightness between the filter and the workbench. You can feel for air leakage by gently blowing on the edge of the filter. If it feels like there is a significant air leak, it may be that the sealing strip is improperly installed or the filter is not installed in place and needs to be readjusted.
Power-on test
After installing the filter, plug in the workbench and turn on the device. Observe the airflow of the workbench and check for abnormal noise or vibration. At the same time, a professional dust particle counter (if available) can be used to detect the air quality in the work area and ensure that the filter is working properly.
Second, vertical flow table filter replacement
(1) Preparation
Prepare tools and materials
Have a climbing tool, such as a small ladder or climbing platform, as the filter for the vertical flow table is usually located at the top. Also, get a screwdriver, wrench (if needed), clean gloves, plastic sheeting or plastic wrap, and a new filter that matches your workbench model.
Safety measure
Turn off the power to the workbench and unplug it to ensure that no electric shock occurs during the replacement process. Clean the items on the workbench and place them in a safe place to avoid falling and damage during operation.
(2) Find the filter location
Fix position
The filter of the vertical flow table is generally located below the top fan. Some workstations have a detachable maintenance panel at the top that can be opened by unscrewing or releasing the clasp; Some may need to remove part of the casing before reaching the filter.
Refer to the workbench's user manual or the markings on the device to determine the exact location of the filter.
(3) Remove the old filter
Open the maintenance panel or cover
If there is a maintenance panel, use a screwdriver to remove the screws and remove the panel. If part of the shell needs to be removed, follow the instructions carefully and keep the screws and components removed.
During the removal process, care should be taken to avoid damaging other components of the workbench, such as fans and electrical circuits.
Loosen the fixture and remove the old filter.
Find the holding device for the filter, which may be a screw, clip, or other holding method. After loosening these fixtures, carefully remove the old filter from the top. Due to the high position of the filter, special attention should be paid to prevent the filter from falling, and it is best to have another person nearby to assist.
Put the old filter into a plastic bag and seal it to reduce the spread of dust.
(4) Install new filters
Check the installation environment and new filters
Before installing the new filter, check that the top mounting position is clean. Wipe the installation slot or frame with a clean, damp cloth to remove dust and impurities. At the same time, check whether the appearance of the new filter is intact to ensure that its specifications meet the requirements.
Install new filter
Place the new filter in the top mounting position in the correct direction. Observe the installation direction sign on the filter to ensure that it is consistent with the airflow direction of the workbench (top-down).
Secure the filter and install it securely using screws or a clasp. If other shell components or maintenance panels need to be installed during installation, perform the operations in the reverse order of removal to ensure that all components are properly installed.
(5) Check the installation
Tightness check
After installation, check the tightness between the filter and the top of the workbench. You can determine whether there is an air leak by placing a thin piece of paper on the edge of the filter and observing whether the paper flutters after opening the workbench. If the slip flutters obviously, it may be a bad seal and needs to be re-checked and adjusted.
Power-on test
Plug it in and turn on the workbench. Check whether the sound of the fan is normal and the airflow in the working area is stable. The dust particle counter can be used to check the air quality of the work area to ensure that the new filter is working properly and provide a good clean environment for the work area.
