200-degree high temperature resistant air filter filtration efficiency
200-degree high temperature resistant air filter filtration efficiency200-degree high-temperature resistant air filters usually have medium-efficiency and high-efficiency filtration efficiency to choose from. Medium efficiency high-temperature resistant filters can filter particles of a certain size, meeting some scenarios where air cleanliness requirements are not so high. High-efficiency high-temperature resistant filters have higher filtration accuracy, can capture smaller suspended particles and air impurities, and ensure the output of purer air.As mentioned earlier, glue has an important influence on the filtration efficiency of high temperature-resistant air filters. When using 250℃ red high-temperature silicone and 350-400℃ black high-temperature inorganic glue, due to the poor fluidity of the glue, the actual filtration efficiency of the 250℃H13 high-temperature resistant filter is between H12-H13; the actual filtration efficiency of the 350-400℃H13 high-temperature high-efficiency filter is between H11-H12. This is because the organic silicone and inorganic glue used in the high-temperature resistant high-efficiency filter are cured from the surface to the inside, and the thicker the injection height, the more difficult it is to cure. If an incompletely cured high-temperature and high-efficiency filter is directly installed on a high-temperature device for normal use, it will cause the high-temperature glue to crack, expand, and the glue to detach from the outer frame. In order to ensure the filtration efficiency of the filter, we can take some measures. For example, before use, let the filter stand for 7 days before normal use, or in the case of urgent installation, first slowly heat it to 100°C in the high-temperature equipment, and then keep it at a constant temperature for 2 hours before stopping and cooling. This allows the glue to fully solidify and ensures that the filter's filtration efficiency is stable at a high level. In short, when choosing a 200-degree high-temperature resistant air filter, it is necessary to consider the difference in filtration efficiency between medium efficiency and high efficiency according to actual needs, and also pay attention to the effect of glue on filtration efficiency, and adopt the correct method of use to ensure that the filter can play the best filtration effect. |
