High-Temp. HEPA Air Filter

A high-temperature HEPA air filter is a specialized air filter that is designed to operate in high-temperature environments. HEPA (High-Efficiency Particulate Air) filters are air filters that are able to remove 99.97% of particles that are 0.3 microns or larger in size. They are commonly used in cleanrooms and other controlled environments, where they are used to remove particles and contaminants from the air in order to maintain a high level of cleanliness.
High-temperature HEPA air filters are specifically designed to operate in environments where the temperature is higher than the maximum operating temperature of standard HEPA filters. This typically means temperatures above 100 degrees Celsius (212 degrees Fahrenheit). High-temperature HEPA air filters are typically made using materials that can withstand high temperatures, such as stainless steel or high-temperature synthetic fibers.
High-temperature HEPA air filters are commonly used in industrial applications, where they are used to remove particles and contaminants from the air in high-temperature environments. They are also used in other specialized applications, such as in air filtration systems for nuclear power plants and other high-temperature environments. When choosing a high-temperature HEPA air filter, it is important to consider the specific requirements of your application, such as the temperature range, the level of cleanliness required, and the types of particles that need to be removed from the air. By carefully evaluating these factors, you can determine the right high-temperature HEPA air filter for your needs.

High-temperature HEPA/ULPA air filters withstand high mechanical load capacities and can be used to filter suspended solids such as viruses, bacteria, toxic dust, and aerosols, and in environments that require sterile or dust-free air.
High-temperature HEPA/ULPA air filters are designed to withstand operating temperatures up to 350˚C and will perform well in situations where frequent temperature fluctuations occur. This air filter comes with corrugated stainless steel baffles and stainless steel support rods and brackets. This provides high overall durability and is less prone to oxidation. The risk of oxide particles falling off the separator on the air exit side is reduced. The baffles are kept in a staggered position to increase media pack stiffness and prevent the nesting of the baffles. The latest design of high-temperature HEPA/ULPA air filters also includes elastic fiberglass sealants instead of the more fragile ceramic sealants commonly found in traditional air filter types. This allows it to better compensate for thermal tensile stresses from components. This design effectively prevents stress cracks from damaging the filtration performance of the air filtration integrity, thereby reducing the risk of bypass, particle shedding, and process contamination.

The high temperature HEPA/ULPA air filter can achieve a filtration efficiency of ≥99.99% for 0.3μm particles at a temperature of 350°C, and an efficiency of ≥99.95% for MPPS. The air filter can operate at a high airflow rate of 1,440m3/h in a 150mm depth implementation and 2,100m3/h in a 290mm depth implementation. Youth’s unique design enables rapid temperature control, which can significantly reduce heating times. The high durability of the overall structure of the air filter effectively controls the risk of downtime during production, while the low operating resistance of ≤250 Pa reduces energy costs.
