Nine key points for laboratory air shower maintenance:

1. Regularly use the instrument to measure various technical indicators of the equipment. If it does not meet the technical parameter requirements, it should be dealt with in time.

2. According to the actual usage, regularly remove and clean the filter material in the primary air filter.

3. When it is found that the wind speed becomes small, first check whether the surface of the primary air filter is black. If it is black, it means that the pre-filter has a lot of dust and the resistance increases, that is, the non-woven filter in the primary air filter should be removed. cloth to be cleaned or replaced.

4. When the wind speed cannot be increased after replacing or cleaning the non-woven fabric, it means that the high-efficiency air filter has been blocked, resulting in increased resistance, and the high-efficiency air filter should be replaced.

5. When replacing the high-efficiency filter, the spray ball plate must be removed, the high-efficiency filter must be taken out, and a new high-efficiency air filter must be replaced according to the specifications and models of the original high-efficiency filter. When installing, confirm the arrow mark on the high-efficiency filter, and the arrow should point to the direction of airflow. And make sure the seal is good to prevent leakage.

6. After the high-efficiency filter is replaced, it is necessary to confirm that there is no leakage in the frame, and use a dust particle counter to detect it. It can only work normally after reaching the technical index.

7. Check and repair the electrical circuit regularly. If there is a fault, you can refer to the electrical schematic diagram for maintenance.

8. Regularly protect the door so that the electronic lock is aligned with the keyhole to prevent the lock pin from getting stuck.

9. The operating temperature of this equipment shall not exceed 50°C, and the use of open flames is strictly prohibited. The filtration effect of the air shower directly affects the efficiency of the production of products.
