 2021-01-06 | View:478

High-pressure filters are more expensive than ordinary filters. Although the effect is much better than ordinary filters, they are still outdated for a while. So how to determine when the high-pressure filter needs to be replaced?
1. How to determine the scrapped high pressure filter
1. In the environmental test, it was found that the suspended particles in the room were significantly higher. After eliminating other causes, the diffuser of the high-efficiency air supply port was removed, the surface of the air supply port was damaged, and black and gray marks appeared. If the equipment cannot be used, a new high-pressure filter should be replaced in time. If the filter is not obviously damaged, please use the air outlet of the airflow cover to measure the air supply volume of each air supply port, and then increase and replace the air supply volume.
2. If the other high-pressure filters are not abnormal, if the air supply of the air outlet of the room is less than half of the standard air supply, it indicates that the filter is clogged and the clogged filter should be replaced.
2. Replacement of high pressure filter
Remove the diffuser plate of the waste high-pressure filter, loosen the fixed parts of the filter, remove the filter, and check the static pressure box, fixed parts and panels for corrosion and loss. If rust is found, rust removal and rust removal paint are required. According to the specifications and quantity, a new type of high pressure filter is used. Check whether the outer packaging of the high-pressure filter is intact. The certificate of the filter should be complete, the frame should be strong and durable, the filter paper should not be damaged, clean and dry, and the inner packaging should be kept intact before installation.
