Maintenance of hepa filter is a very important problem, then how to maintain the hepa filter? First, let's take a look at hepa filters: hepa filters are mainly used to capture particles of dust and suspended solids up to 0.3um. It is made of ultrafine fiberglass paper as a filter material, offset paper, aluminum film and other materials as a partition, and a hepa filter frame. Each set has been tested and has the characteristics of high filtration efficiency, low resistance and large dust capacity. How to maintain high efficiency filter?
1. Do not tear or open the packaging bag or film by hand before installing the hepa filter. The air filter should be stored in strict accordance with the direction standard marked on the packing box of high efficiency filter. When operating hepa filters, care should be taken to avoid violent vibration and collision.
2. The hepa filter shall be transported and stored in the direction indicated by the manufacturer. In the process of transportation, please handle with care to avoid violent vibration and collision, and do not force the loading and unloading of goods.
3. Before installing the hepa filter, the packaging must be unpacked at the installation site for appearance inspection, including: filter paper, sealant and frame damage; Whether the side length, diagonal and thickness meet the requirements; Whether the frame has burrs and rust spots (metal frame); Whether the product certificate is available, and whether the technical performance meets the design requirements. The inspection shall then be carried out in accordance with the method specified in the national standard specification "construction and acceptance of clean rooms" [jgj71-90], and a qualified clean room shall be installed immediately.
4. For the high efficiency filter, the installation direction must be correct: when using the corrugated plate combination filter in the vertical installation, the corrugated plate must be perpendicular to the ground; The vertical connection between the filter and the frame prohibits leakage, distortion, damage and glue leakage. After installation, the inner wall must be clean and free from dust, grease, rust and sundries.
