High efficiency filtration: these filters usually have extremely high filtration efficiency, which can effectively capture and filter out airborne particulate matter, such as dust, bacteria and viruses, with an efficiency of over 99.9%.

High-temperature resistance: designed to withstand the challenges of high-temperature environments, they can work for a long time in environments ranging from 250°C to 350°C, ensuring the stability and reliability of the filters under extreme conditions.

Solid structure: designed with a partition, which is usually made of aluminum foil or other high-temperature-resistant materials, it can effectively protect the filter element from deformation or damage of the filter paper under high-temperature environments.

Large dust capacity: high temperature resistant high efficiency filters have a large dust capacity due to their special structure and materials, which means they can filter more particles without clogging.

Low resistance: even at high temperatures, the resistance can be kept low to ensure unobstructed air flow, which is crucial to maintaining the normal operation of the system.

Wide range of applications: High-temperature-resistant high-efficiency filters are not only suitable for high-temperature environments, but can also be used in a wide range of applications that require high-cleanliness air, such as pharmaceuticals, food processing, hospital operating rooms and so on.

Usage environment

High-temperature-resistant high-efficiency filters are able to work continuously in environments ranging from 250℃ to 400℃, and some can even withstand temperatures as high as 330℃. These filters are suitable for a wide range of environments, including but not limited to petroleum, pharmaceutical, automotive, light industry, food and other industries, especially in the need for high-temperature drying of ultra-clean ovens or high-temperature air purification requirements of the system performance is particularly outstanding.

Performance characteristics

The performance characteristics of high-temperature-resistant high-efficiency filters mainly include high filtration efficiency, low resistance, large dust capacity, as well as excellent chemical resistance and low moisture absorption. The filtration efficiencies typically range from 99.99% to 99.999% @ 0.3 μm and meet the H13 or H14 classes of the EN1822 standard.

Application Areas

High temperature resistant high efficiency filters have a wide range of applications in several fields due to their special properties. In addition to the industries mentioned above, they also cover liquid crystal display and chip industries, etc. In these fields, they are mainly used to filter airborne particles above 0.3μm and protect product quality and environmental hygiene in the production process.

Installation and Maintenance

When installing high-temperature resistant HEPA filters, it is necessary to pay attention to whether the size and installation of the filter match the existing system, and to confirm whether there are any additional requirements such as liquid tank sealing or DOP testing. For maintenance, once the filter is found to have holes or efficiency degradation, it should be replaced in time to ensure the normal operation of the system.

Design Features

High Temperature Resistant Separated High Efficiency Filter is a filtration device designed for filtering airborne suspended particles above 0.3 micron. Its core component is a filter media made of high-temperature-resistant ultra-fine glass fiber filter paper separated by dividers formed by aluminum foil sheets or other materials. This design not only ensures equal spacing of the filter media, but also makes it easy for airflow to pass through, thereby improving filtration efficiency and enhancing overall strength. In addition, the periphery of the filter is sealed with a special high-temperature-resistant sealant to ensure the sealing and stability of the entire filter. Each filter is rigorously tested before leaving the factory to ensure that its performance is up to standard.

Filtration efficiency grade

The filtration efficiency class of high temperature resistant compartmentalized HEPA filters is usually H13 or H14 (EN1822 standard), which means that they are capable of filtering out at least 99.97% or more of 0.3 micron particles under specific conditions. This high filtration efficiency makes them ideal for use in environments that require high levels of cleanliness, such as high temperature ovens, baking ovens and other heated equipment in the electronics, pharmaceutical, food and other industries.

Material composition and operating conditions

The construction of high temperature resistant compartmentalized HEPA filters includes, but is not limited to, a peripheral frame such as an aluminum profile frame, a galvanized frame, a stainless steel frame, etc. The interior is filled with high temperature resistant microfiberglass filter paper and sealed with red high temperature resistant silicone as a sealant. In addition, auxiliary materials such as protective mesh and stainless steel chevron mesh may be included. Together, these materials form the filter's high-temperature resistant structure and efficient filtration performance.

Product dimensions and specific parameters

The dimensions and parameters of the high-temperature resistant compartmentalized high-efficiency filters can be customized to meet the needs of different applications. Common sizes include, but are not limited to, 320320150mm, 484484150mm, 610610150mm, etc., and the corresponding parameters such as rated airflow, filter area, dust holding capacity and resistance will also vary. The exact values of these parameters will vary depending on the design of the filter and the conditions of use, but overall they provide stable and reliable filtration performance in high temperature environments.
