Polyester tri-proof needle felt can add compounded conductive material according to the special working conditions and dust features of cements so as to reduce the static caused by the friction effectively.

Based on the common anti-static needle felt, through special chemical treatments, tri-proof polyester needle felt has the functions of water-poof and oil proof. After the nano waterproof and oil proof treatments, tri-proof polyester needle felt has the lotus leaf effect which means the water or oil cannot soak the surface of the filter bags easily, thus fix the problems of dewing and blocking.

Tri-proof needle felt with the properties ofanti-static, anti-dewing, high dust collection efficiency, strong strength, high porosity, low resistance for gas filtrationand suits for the working conditions with large humidity.
