FILARS® – FILTERING NEEDLED FELT FROM ARSELON® FIBER

FILARS® – FILTERING NEEDLED FELT FROM ARSELON® FIBER

Arselon filtering felt Filars® is designed for hot gas filtration. It is pure 100% Arselon fiber, with chemical description as poly-para-phenylene-1,3,4-oxadiasole.
High thermal resistance is a key property to use bag filters at temperature 250 °C up to 3 years with peak level at 400 °C without melting or shrinkage.
The felt is reinforced with scrim fabric made from Arselon filament. Thus, high strength and wear resistance are guaranteed.
To make regeneration while in filtration process faster the felt is calendered.

Filars is high resistive to organic acids and solvents as well as oils. Medium resistance to inorganic acids and alkalis. The fiber has very good electrical insulation properties.

APPLICATION

Hot gas filtration in metallurgic plants, cement, asphalt works.
