Precautions for installing industrial high-efficiency air filters in clean rooms
Precautions for installing industrial high-efficiency air filters in clean roomsThe air filter is the core of the air purification system, and the end high-efficiency filter is the key to the entire system. Industrial high-efficiency air filters are mostly used for terminal filtration at the top of clean rooms. The main filter materials of high-efficiency filters are ultra-fine glass fiber paper and ultra-fine Asbestos fiber paper, to ensure the filtration efficiency of the filter and the cleaning effect of the clean system, the installation of high-efficiency filtration must comply with the "Clean Room Construction and Acceptance Specifications".To avoid contamination of the high-efficiency filter when installing an industrial high-efficiency air filter, the air purification system must be installed. The air conditioner, high-efficiency filter box, air duct, and clean room must be cleaned, and the straightness of the filter frame or edge end face must be checked. The allowable deviation of the end face flatness. If the deviation exceeds the deviation value, only the end face of the frame where the filter is installed is allowed to be modified or adjusted. The filter itself cannot be modified, otherwise, the filtration efficiency will be affected. During installation, the airflow direction should be consistent with the direction of the arrow mark on the outer frame. Its sealing generally adopts two methods: the top-tightening method and the compression method. When installing the galvanized frame high-efficiency filter, the filter should be handled with care to avoid contamination. Do not hit or hit it with tools, and it is strictly forbidden to touch it with your hands or tools. Filter paper to prevent damage to the filter material and sealant. The above is a brief introduction based on the installation problems encountered by our technicians when they go out for installation. Generally, the high-efficiency air filter in the clean area is installed at the bottom of the clean room, installed horizontally and vertically, as the end filtration of the entire air purification system. The air is sent indoors through the filter. |
