High-temperature air filters are specialized HVAC components engineered to maintain structural
integrity and filtration efficiency in extreme heat environments where standard filters would
melt or fail. They are typically categorized by their maximum operating temperatures, commonly
ranging from 250°C to 500°C. Specialized filters designed to withstand extreme heat in
sterilization processes.
Key
Benefits
- 🔥 Thermal Stability: Designed to
withstand thermal expansion and contraction without shedding fibres or leaking air.
- 🛡️ Process Protection: Safeguards
sensitive downstream equipment (like heat exchangers) and maintains product purity.
- 📜 Safety & Compliance: Often non-combustible and certified to
international standards like EN 1822 or ISO 16890.
Technical Specifications
- 🌡️ Temperature Ratings: Tiered from
120°C (248°F) up to 500°C (932°F) using advanced ceramic/metal media.
- 🧪 Filter Media: Ultra-fine glass
fibre, ceramic fibres, or stainless steel mesh for extreme heat.
- 🏗️ Frame & Construction: Made from
SUS304 stainless steel, galvanized steel, or aluminized steel.
- 🔘 Separators & Sealants: Corrugated aluminium foil separators;
High-temp silicone or ceramic glue sealants.
