knowledge
With the increasingly serious environmental pollution and people's increasing awareness of environmental protection, air quality has become the focus of world attention. The air filtration system can not only protect products and production equipment, but also protect the health and safety of staff. Therefore, the application scope of air filters is more and more extensive. With the rapid development of high-tech and the combination of primary, middle and high-efficiency filters, the dust particles with smaller particle sizes can be continuously and effectively removed, and the air concentration in clean rooms can be controlled within a certain range.

Installation of clean room high efficiency filter:

1. in the transportation and storage of high efficiency air filters, they should be shelved in the direction of the manufacturer's logo. Transportation should be carried out gently to prevent violent vibration and collision, so as to avoid damage to adults.

2. Before installing the high-efficiency filter, it is necessary to clean, wipe and purify the clean room. If dust accumulates in the air-conditioning system, the high-efficiency filter should be installed immediately after cleaning and wiping the clean room again.

3. clean room and clean air conditioning system to achieve cleanliness requirements, the clean air conditioning system must be tested. Continuous operation of 12h or more, once again clean and wipe clean room immediately after installation of high efficiency filter.



4. Before installing the high-efficiency air filter, it is necessary to open the package on the installation site for external inspection, including filter paper, sealant and frame whether there are burrs and metal frames: whether there is product certification, whether the technical performance meets the design requirements. Then pick up the leak. After inspection and leak collection, it should be installed immediately. When installing, each filter should be properly adjusted according to its resistance. For one-way flow, the difference between the rated resistance of each filter and the average resistance of each filter on the same tuyere or air supply surface should be less than 5%.

5. the framework for installing high efficiency filters should be smooth. The installation tolerances of each high efficiency filter are not greater than 1mm. And keep the arrow on the outer frame of the filter consistent with the direction of the airflow. When vertically installed, the crease of filter paper should be perpendicular to the ground.

6. The sealing between the high-efficiency filter and the frame generally adopts sealing gasket, non-drying glue, negative pressure seal, liquid tank seal and double-ring seal, etc. All the packing surface, filter frame surface and the frame surface and liquid tank must be wiped clean. The thickness of the gasket should not exceed 8mm, and the compression rate is 25%~30%. The joint form and material should conform to the design requirements, and there must be no leakage at all joints of the frame. When Using Double-Ring sealing strip, do not plug the hole in the ring cavity when pasting sealing; double-ring sealing and negative pressure sealing must keep the negative pressure feeling unobstructed.

7. At present, most domestic filters are installed by sealing gasket method, because the sponge rubber plate is closed-cell type, with good air tightness, so it is generally used as a sealing material. If necessary, it is better to place some glass glue on the sealing strip. When the filter is connected with the static pressure box, the force around it should be even. After 24 hours, the glass glue dries in the running purification system.
