Standard HEPA packs rely on organic adhesives and separators that soften well below 200°C. High-temperature builds replace every organic component with inorganic separators, heat-cured bonds and a full metal frame.
250°C continuous service with excursions to 350°C: matched to drying ovens, depyrogenation tunnels and sterilizer exhaust where clean air and hot air are the same requirement.
