However, where synthetic fiber filters reach their limits at around 250癈, with ceramic filter elements flue gases up to 1,000癈 can be filtered: The microporous filter material made of high temperature wool boasts its strengths. RATH has been developing innovative hot gas filter elements for many years, because those who are familiar with refractory technology are also predestined for hot gas filtration.
