Disposable Bonded Microfibre Filters Headline disposable filter elements are manufactured from precise mixtures of borosilicate glass microfibres, to the very highest standards of quality control. These elements offer exceptional filtration efficiency at very low pressure drops and, being 90+% void volume, give very long service life. The elements are self-gasketing and easily sealed into the housing by axial compression. The elements are bonded to impart high strength and eliminate fibre shedding. The choice between the different binders available will depend upon the application conditions. Filter Element Efficiency Each element type is available in a wide range of grades of efficiency, covering the complete range from coarse bulk contamination removal (grade 80) and the essentially complete removal of submicron particles (grade 40). Grade designations, removal of 0.1 micron particles 99.9999+% = Grade 40 99.99+% = Grade 50 99.5%+ = Grade 60 95+% = Grade 70 75+% = Grade 80 Filter Element Dimensions All disposable filter elements have a part number arranged with three figures, e.g. 25-64-70. The first part refers to the inside diameter of the element in millimetres, the second figure refers to the overall length of the element in millimetres and the third part refers to the grade designation. Replace the ‘xx’ in the part numbers with the grade designation.
