FILTRE A TRES HAUTE EFFICACITE

摘要

The disclosed filter is comprised of a frame (1) made of a geopolymer and essentially comprised of a U-shaped section of which the concavity is turned inwardly. The body of the filter (3) is encased in a cast mass (2) of geopolymer which adheres to the internal wall of the section. Such construction provides for a perfect tightness at the fixing interface of the filter body (3) despite very high temperature variations that the filter may undergo. Application to ultrahigh efficient filters operating at high temperatures.
