What are the maintenance and maintenance methods of the air shower room?

The maintenance and maintenance of the air shower room is essential for its normal operation and service life, the following are some of the main maintenance and maintenance methods:
First, the maintenance of the primary filter
Periodic inspection
The primary filter is the first line of defense of the air shower, which is used to filter impurities such as dust or larger particles. The primary filter should be inspected once a week or every two weeks to see if there is obvious dust accumulation, deformation, or damage on the filter surface. For example, by observing the inlet and outlet air sides of the filter, if a large amount of dust is found on the inlet air side, and dust traces begin to appear on the outlet air side, it indicates that the filter may be closed to saturation and needs to be cleaned or replaced.
Cleaning method
When the primary filter is found to have a lot of dust, a vacuum cleaner can be used to clean it. When cleaning, pay attention to vacuuming from the air inlet surface of the filter, and the action should be gentle to avoid damaging the filter material of the filter. If the dust accumulation is too stubborn, you can also remove the filter, rinse it with warm water of no more than 40 ° C, rinse it naturally dry or dry it at a low temperature (temperature no more than 60 ° C), and ensure that the filter is completely dry before installing it back.
Replacement cycle
Under normal circumstances, the service life of the primary filter is about 3-6 months, and the specific replacement cycle needs to be determined according to the frequency of use of the air shower room, the dust content of the surrounding environment, and other factors. If the filter is seriously deformed, or damaged, or the filtration effect is still poor after repeated cleaning, it should be replaced in time.
Second, high-efficiency filter maintenance
Check the frequency and key points.
The high-efficiency filter is mainly used to filter small particles and ensure the air cleanliness of the air shower room. Due to its high filtration accuracy and relatively fragile, it should be inspected once a month, focusing on whether the sealing strip of the filter is intact and whether there is air leakage. For example, you can use your hand to feel whether there is an air leak around the filter frame or use a smoke generator to produce smoke on one side of the filter and observe whether there is a smoke leak on the other side to determine whether there is air leakage.
Professional maintenance and replacement
High-efficiency filters are generally not recommended to clean themselves, because improper cleaning operations are easy to damage the filter material. If the high-efficiency filter is found to be blocked, or damaged or the filtration efficiency is significantly reduced, it should be tested and replaced by professionals. The replacement cycle of the high-efficiency filter is usually about 1-2 years, but in an environment of poor air quality or frequent use of the air shower, the replacement cycle may be shortened.
Three, fan maintenance
Routine inspection
The fan is the power core of the air shower, and the fan should be checked briefly every day or before each use. Including checking the fan running sound is normal, there is no abnormal vibration, and so on. The sound of the fan in normal operation should be stable and continuous. If the fan is heard with harsh, friction or irregular vibration, it may indicate that there is a problem with the impeller, bearing, or motor of the fan.
Regular maintenance
The fan should be fully serviced every 3-6 months. Clean the dust and debris on the impeller and shell of the fan to avoid dust accumulation affecting the performance of the fan. At the same time, check the bearing of the fan, and add or replace grease to ensure that the bearing is well lubricated. For belt-driven fans, it is also necessary to check the tightness of the belt and adjust it if necessary to prevent the belt from slipping and affecting the speed of the fan.
Four, door maintenance
Tightness check
The tightness of the air shower door is directly related to the overall performance of the air shower room. Periodically (at least once a month) check the door sealing strip for aging, deformation, or damage. You can test the sealing condition by placing a thin strip of paper around the door after closing it, and then gently pulling the strip. If the strip is easily pulled out, it indicates that the door is not sealed well.
Cleaning and lubrication
Keep the door clean, and regularly clean the surface of the door dust and stains, to prevent them from entering the door track and lock. At the same time, the track and hinge of the door and other moving parts are lubricated, you can use an appropriate amount of lubricating oil or grease to ensure that the door is switched smoothly, and avoid the normal use of the air shower due to the door's deadlock.
Five, electrical system maintenance
Regular circuit inspection
Check the electrical system of the air shower room every quarter to see if the wires are damaged, aging, short circuits, and so on. Focus on checking the wiring connecting fans, filters, lighting equipment control panels, etc., to ensure that the insulation layer of the wire is intact and the connection is strong.
Control panel maintenance
Keep the control panel clean to prevent dust and moisture from entering the inside of the panel. For touch-screen control panels, care should be taken to prevent sharp objects from scratching the screen. If the buttons and indicators on the control panel are found to be faulty, the corresponding components should be replaced in time to ensure that the functions of the air shower can be normally controlled.
6. Overall cleaning and disinfection
Internal cleaning
Regular (at least once a month) thorough cleaning of the air shower, including walls, floors, and internal equipment. Wipe the interior surface with a mild cleaner and a clean rag to remove dust and stains. In the cleaning process, avoid cleaning agents into the fan, filter, and other key equipment.
Disinfection treatment
According to the requirements of different places of use such as electronics factories and pharmaceutical factories, regular disinfection of air shower rooms may be required. You can use an ultraviolet disinfection lamp, disinfectant spray, and other ways to disinfect. For example, in the air shower room of food processing enterprises, food-grade disinfectants can be used for spray disinfection every week and then wiped clean with water to ensure that the environment in the air shower meets health standards.
