The key to air shower protection: regularly use the instrument to determine the technical indicators of the equipment, if it does not meet the technical parameters, it should be dealt with in time. According to the practical application, the filter material in the primary air filter is removed and cleaned regularly. When it is found that the wind speed becomes small, it is necessary to first check whether the appearance of the primary air filter is black.

If it is black, it means that the pre-filter has more dust and the resistance is increased. That is, the non-woven fabric in the primary air filter should be removed for cleaning or interchange. When the non-woven fabric is exchanged or cleaned, the wind speed cannot be improved. If the high-efficiency air filter is now blocked and the resistance is increased, the high-efficiency air filter should be replaced.

When replacing the high-efficiency filter, the ball-splashing plate must be removed, the high-efficiency filter removed, and the new high-efficiency air filter replaced with the original high-efficiency filter model. The device should recognize the arrow symbol on the high efficiency filter and the arrow should point in the direction of the air flow. And to ensure that the seal is outstanding, to avoid leakage.

After the high-efficiency filter is replaced, it is necessary to recognize that there is no leakage on the frame, and use the dust particle counter to detect it. After reaching the technical index, normal operation can be performed. Regularly check and repair the electrical circuit. If there is any problem, refer to the electrical schematic for repair. Enclose the door at regular intervals to align the electronic lock with its keyhole to prevent the lock pin from being stuck. The operating temperature of this equipment must not exceed 50 °C, and the use of open flames is prohibited.
