Characteristics of High-temperature HEPA Filters

July 10, 2023

In daily life and production, there are many models and manufacturers of air filters, and we have rich industry experience. Many industrial manufacturers choose to order filters, especially high-temperature HEPA filters. So, what are high-temperature HEPA filters? What unusual functions do they have?

The use of baffles is the main method employed in high-temperature HEPA filters. The corrugated structure of the baffle not only improves material utilization but also effectively protects the material, playing a crucial role. It is a special pleating method where the filter material has two folds when bent, folding it into a box-shaped pleat, which greatly prevents material damage.

Characteristics of high-temperature HEPA filters:

1. Baffle structure, using ultra-fine, alkali-free, high-temperature resistant glass fiber filter paper.

2. Aluminum foil as the separator, moisture-proof, temperature resistant, and prevents shrinkage deformation.

3. Glass long fibers are used as the filter material and fixed with a diamond-shaped mesh, making it resistant to deformation.

4. Galvanized frame, stainless steel frame, and specially made high-temperature resistant sealant for sealing.

5. Low resistance, high efficiency, good temperature resistance, suitable for long-term use in high-temperature environments.

6. Each HEPA filter undergoes strict testing.

7. Excellent chemical resistance, low moisture absorption, flame resistance, and can withstand temperatures of 250-300°C.

8. Frames are available with no flange, single flange, or double flange.

9. Can be customized according to customer requirements.

The working temperature range of high-temperature HEPA filters is limited. Although they have high-temperature resistance, they are only suitable for temperatures below 450°C and need to work in highly clean environments, such as pharmaceutical production lines, food processing, chemical engineering, electrical engineering, biotechnology, as well as special environments in the film and industrial fields, where they show excellent performance.

They are mainly made of high-temperature resistant metals and various inorganic materials, allowing for long-term use in high-temperature environments, with exceptional stability and durability. The aesthetic appeal of high-temperature HEPA filters is enhanced by their metallic structure, which is particularly important for clean environments. Therefore, the unique characteristics of high-temperature filters, as seen in this way, make them widely used in popular cleaning equipment on the market today. Whether in clean rooms or on industrial production lines, this type of filter is particularly favored.

Therefore, having a good understanding of the basic knowledge and characteristics of these filters will enable us to better maintain and handle cleaning equipment in the future. Due to the unique features and advantages of high-temperature HEPA filters, many owners have chosen to use them. When using these devices, we must select responsible production companies and manufacturers, as it is also in our own interest to do so.
