Glass Fibers Membrane Without Binder manufactured by GVS Group is made of 100% borosilicate glass fiber without binder. The filter combines depth structure with its large surface area to provide an outstanding impurity retention capacity while maintaining a low filter resistance. Glass fiber filters is able to adsorb the finest particles down to 1 μm from liquids and < 1 μm in air and gases, as the electrostatic interaction between the glass fibers and gases is better than between glass fibers and liquids.
