For the high temperature resistance HEPA filter H13, the following is a detailed analysis of its performance:
1. Filtration efficiency
The H13 high temperature resistance HEPA filter has a very high filtration efficiency for particulates in the air. It can effectively filter out airborne particles with a diameter of 0.3 microns and above, and the filtration efficiency is usually between 99.97% and 99.99%. This means that after passing through the H13 filter, the vast majority of particles in the air will be intercepted, thus ensuring the cleanliness of the clean room air.
Second, temperature resistance
High temperature resistance HEPA Filter H13 offers excellent temperature resistance. Its instantaneous high temperature resistance can generally reach 300 ° C, and long-term use, the constant temperature can also reach about 260 ° C. If the use of black high temperature inorganic adhesive resistant to 350~400℃, the filter can also maintain a certain performance in this temperature range. This enables the H13 filter to operate stably in high temperature environments, meeting the needs of some special industries.
Third, material and structure
Filter material: H13 high temperature resistance HEPA filters usually use high temperature resistant glass fiber or ultra-fine glass fiber filter paper as filter material. These filters have the advantages of high filtration accuracy and stable performance, and can maintain stable filtration performance in high temperature environments.
Separator: The filter is usually equipped with a separator inside, which is used to support the filter material and maintain its shape. The baffle material is usually 0.03mm aluminum foil baffle or other high temperature resistant material, and the circular corrugated groove can protect the filter paper and allow the wind speed to pass through evenly.
Outer frame: The outer frame material is generally stainless steel or other high temperature resistant metal materials, with high strength and corrosion resistance. The stainless steel frame can maintain stable structural properties in high temperature environments, ensuring the overall stability of the filter.
Fourth, resistance and air volume
Resistance: The resistance of the H13 high temperature resistance HEPA filter is relatively low. With the accumulation of dust during use, the resistance will gradually rise. When the resistance reaches a certain level, the filter needs to be replaced to ensure filtration efficiency.
Air volume: The air volume of the filter is usually selected according to the actual demand. Common specifications have different air volume adaptation, such as rated air volume may be 1000 cubic meters/hour, 2000 cubic meters/hour and so on. Users can determine the required air volume according to the area of the clean room, air flow speed and other factors.
5. Application occasions
H13 high temperature resistance HEPA filters are widely used in a variety of applications requiring high cleanliness and high temperature environments. For example, in the fields of electronics manufacturing, biomedicine, aerospace and so on, there are strict requirements for the number and temperature of particles in the air. The H13 filter meets these requirements, ensuring the cleanliness and temperature stability of the production or laboratory environment.
In summary, the H13 high temperature resistance HEPA filter has excellent filtration efficiency, excellent temperature resistance, high-quality material and structure, and a wide range of applications. It is one of the indispensable important equipment in the clean room, which can effectively improve the cleanliness and temperature stability of the indoor air.
