Micro-glass fiber media made of borosilicate glass fiber without binders or with binder. The small diameter fibres give micro glass media superior efficiency and dirt holding as compared to cellulose and synthetic media. The chemical resistance to most solvents and reagents is very good. It offers High flow velocity yet high efficiency for the retention of small and even smallest particles, combined with good permeability and high dirt holding capacity. It also featured excellent wet strength for easy handing and filter integrity.
