1. High-temperature high-efficiency filters are mainly used to filter dust particles larger than 0.3 microns, with a filtration efficiency greater than or equal to 99.99%.
2. Compared with ordinary high-efficiency filters, high-temperature high-efficiency filters can only be used in special places, such as high-temperature sterilization clean equipment production, the high-temperature air supply at the end of purification equipment with high cleanliness requirements, and high-temperature clean oven purification equipment.
3. It uses ultra-fine glass fiber paper as the filter material, with characteristics such as high filtration efficiency, low resistance, and large dust holding capacity. Each unit undergoes product performance testing and filtration effect testing after completion.
4. In high-temperature environments, different constant temperatures require different high-temperature high-efficiency filters, mainly because the temperature-resistant adhesives used in their manufacture are different, and the temperatures they can withstand are also different.
5. The materials of high-temperature filters and ordinary filters are very different. The outer frame of high-temperature high-efficiency filters usually uses a galvanized frame or a stainless steel frame. The sealing strip uses a special high-temperature sealing gasket, and the sealant uses high-temperature adhesive; above 350 degrees, ceramic adhesive is used.
6. General 250-degree Celsius high-temperature high-efficiency filters contain silicon, while 400-degree Celsius filters do not. Therefore, users, especially those in the chemical industry, need to understand whether their equipment has silicon requirements when purchasing high-temperature high-efficiency filters.
