High-Temperature HEPA Box Filter, H14, 300°C (CAT#: STEM-BC-0157-ZJF)

The high-temperature HEPA box filter is designed for air purification equipment operating under elevated temperature conditions. It uses low-resistance ultrafine glass fiber filter paper with aluminum foil separators. The frame can be made from aluminum alloy, stainless steel, or galvanized steel depending on the installation requirement. High-temperature sealant is used to maintain sealing stability during continuous high-temperature operation. The filter is mainly used in hot air purification applications such as ovens in lithium battery cell production. H11, H13, and H14 filtration grades are available. Multiple dimensions and airflow ratings support different equipment capacities. The structure is suitable for long-term use in 250°C and 300°C environments.
