High-temperature air filters capture airborne particles in heated air streams within their specified operating limits. Spycor Environmental lists Glasfloss Magna HT filters, available from the manufacturer in MERV 11, 13, and 14 with temperature series spanning 350°F to 900°F.
Magna HT construction includes inorganic glass microfiber media, an aluminized steel frame, aluminum separators, and high-temperature rope gasketing. Industrial facility engineers and HVAC contractors should compare temperature series, dimensions, header configuration, gasket location, and rated airflow before selecting a replacement.
