Efficient filters, with their high-quality characteristics, are widely used in many situations, such as aquaculture circulating water treatment; Cooling circulating water and industrial circulating water treatment; Treatment of eutrophic water bodies such as rivers, lakes, and household water features; In precision electronic instrument factories and other occasions, in order to extend the service life of high-efficiency filters, daily maintenance work should also be done well. The specific maintenance methods are as follows:

1. Before installing the high-efficiency filter, it is not allowed to tear or open the packaging bag or film by hand. The air filter should be stored strictly according to the direction standard marked on the high-efficiency filter packaging box; During the transportation of high-efficiency air filters, they should be handled with care to avoid severe vibrations and collisions.

2. The transportation and storage of high-efficiency filters should be placed in the direction indicated by the manufacturer's logo. During transportation, handle with care to prevent severe vibrations and collisions, and do not force loading or unloading.

3. Before installing the high-efficiency filter, it is necessary to unpack and inspect the appearance at the installation site, including whether the filter paper, sealant, and frame are damaged; Whether the side length, diagonal, and thickness dimensions meet the requirements; Whether the frame has burrs and rust spots (metal frame); Whether there is a product qualification certificate and whether the technical performance meets the design requirements. Then, according to the methods specified in the national standard "Code for Construction and Acceptance of Cleanrooms" [JGJ71-90], the qualified ones should be installed immediately.

4. For high-efficiency filters, the installation direction must be correct: when using corrugated plate combination filters for vertical installation, the corrugated plate must be perpendicular to the ground; The connection between the filter and the frame in the vertical direction must strictly prohibit leakage, deformation, damage, and glue leakage. After installation, the inner wall must be kept clean and free of floating dust, oil stains, rust, and debris.

5. Inspection method: Observe or wipe with white silk cloth for inspection.
