The Role of Medium-Effect Air Filters in Cleanrooms

2024-08-29

Medium efficiency air filter is mainly used in air conditioning and centralized air supply system. It can be used for primary filtration in air-conditioning systems to protect the filters and systems in the system. Where air purification and cleanliness are not important, the air treated by the medium efficiency air filter can be delivered directly to the user. Medium-effect air filters are widely used in air conditioning and ventilation systems, pharmaceuticals, electronics, food and other industrial purification. Medium efficiency air filters can also be used as front-end filtration of air filters to reduce the load on air filters. Extend its service life. The medium-effect air filter (bag filter) adopts cold plate spraying, galvanized plate and other forms. The filter material is non-woven fabric, glass fiber and so on. The particle size of the filter is 1~5um, and the filtration efficiency is high. It is 60~95% (colorimetric method). Filter material is usually divided into: F5 (yellow), F6 (green), F7 (light pink), F8 (light yellow) and F9 (white). ...

1, open the inhalation grille in the device, hold down the buttons on both sides and gently pull down; 2, drag the hook on the air filter to pull out the device to the diagonal bottom; 3, use a similar vacuum cleaner to remove the dust in it, or rinse with warm water; 4, if you encounter too much dust, you can use a soft bristle brush with neutral detergent to clean, clean and dry the water after cleaning and place it in the sun in the cool place; 5, Never use more than 50 ℃ hot water for cleaning, so as to avoid the phenomenon of equipment color or deformation, and do not bake dry on the fire; 6, after the completion of the cleaning must be installed in a timely manner on the equipment, the installation of the equipment will be hung on the upper part of the protruding inhalation grille, and then fixed in the inhalation grille on the inhalation grille, the back of the inhalation grille convex handle to the inward slowly sliding until the entire device pushed into the grille; 7, the final step is to close the inhalation grille, the last step is to close the inhalation grille, the last step is to close the inhalation grille. The last step is to close the suction grille, which is exactly the opposite of the first step, press and hold the filter signal reset on the control panel...

What are the characteristics and uses of high temperature resistant high efficiency filter?

2024-08-29

High-temperature efficient filters have the characteristics of strong heat resistance and higher filtration power, and because of its own advantages, it has a certain application in many categories. Now many enterprises in the process of selecting production production, their own filtration environment is more stringent, for example, the filter needs to work in a high temperature environment for a long time, so the selection of high-temperature-resistant high-efficiency filters. Here we introduce the characteristics and usefulness of high-temperature resistant high-efficiency filters. Characteristics of high-temperature resistant high-efficiency filter. The raw materials used in the high-temperature resistant high-efficiency filter itself are of good quality. For example, the use of ultra-fine glass fiber filter paper as filter material, large filtration area, dust capacity, low resistance, can ensure that the high-temperature resistant high-efficiency filters over the pie precision and over the wave of power, but also the use of galvanized plate, stainless steel plate, etc. as the frame to add the overall strength of the equipment, so that the overall equipment is more robust, stronger resistance, of course, high-temperature resistant high-efficiency filters have another feature that can be seen from the name, is the high temperature resistant high efficiency filters.
