Type GF9 Glass fibre filter, with inorganic binder ,70 g/qm, filter circles, 50

Recommended for the control of air and water pollution and as a pre-filter for membranes. Made from 100% borosilicate glass fibers. Glass fiber filters adsorb liquids from particles up to 1 μm, and even aerosols from air and gases are separated by 0.3 - 0.5 μm. The large surface (about 2 sqm / g) ensures an extraordinary capacity. Extremely low content of metals. Glass fiber filters retain all properties when in contact with acids (except hydrofluoric acid) and / or alkalis at moderate concentrations, as well as at temperatures up to 500 ° C (180 ° C at GF 10). High flow rate and high air permeability.
