The wide variety of materials used to create the filter cartridges provides a wide scope for applications and easy cleaning for even medium and fine filtration retentions. Our filter cartridges each have a number to identify the grade of porosity; the higher the grades, the greater the diameter of the pores and the greater the retention rate of large contaminants. Note, care should be taken when comparing grades for different materials, as each material offers unique benefits over and above the porosity grade.
Every porous material has a characteristic distribution of pores and porosity can be defined by the average pore measurement (MO) or the measurement of the largest pores (LP). These diameters are given as a bubble point. The filtration efficiency and the filter fineness do not depend only on the diameter of the pores, but also on the shape and concentration of the contaminant particles, the velocity of the filtration process and the viscosity of the fluid.
The volume of the pores, or porosity, is calculated as the ratio of empty versus full pores, or the total volume of pores that can be filled by a liquid versus the total volume available on the material. Porosity is, therefore, commonly expressed as a percentage.
Porous elements on filter cartridges should be cleaned to ensure reliable and consistent filtration standards. Traditionally, filter elements are washed in the counter-current, which is suitable if the contaminant is not too viscous (sticky) and if a high enough counter-current pressure can be achieved. The difficultly with this method is that preferential passages can be created for the stream and some pores may be neglected.
The brush and water cleaning method can be used when the contaminant is made of larger particles that are retained on the surface of the filtration material. Alternatively, solvents and aggressive cleaning agents can be used, but only if these will not damage the filter material. If the filter can be cleaned then its life can be substantially increased, with cleaning cycles possible many times over.
Aerolith filter cartridges contain a mixture of crystalline and amorphous silicates, giving a remarkably wide range of potential applications. These filter cartridges give thermal resistance up to 400°C and chemical resistance to hot and cold, neutral and acidic liquids and gases.
Colour: pure white.
These filter cartridges are a mixture of alumina silicates and, avoiding thermal shocks, are stable up to 600°C. Typical applications include liquid filtration, linings for nutsches and support bodies for pre-coat filtration.

The inorganically bonded silicon carbide in Schumalith filter cartridges has very-good resistance to solutions of acids and acidic salts, saturated and superheated steam and hot gases up to °C. In grain size 3, these filter cartridges can be used for the sterile filtration of gases.
Colour: brilliant grey
These filter cartridges are pure carbon, so are very resistant to chemical reactions. The filter elements are not attacked by hydrofluoric acid and can be utilised within the whole pH range, from pH 0 to pH 14. Carbo filter cartridges are stable in oxidising atmospheres up to around 200°C and in reducing atmospheres up to about °C.
Colour: black
Filtroplast filter cartridges have a homogeneous plastic porous structure with an extremely smooth surface, providing high resistance to abrasion and generating no particle release. The chemically resistant material meets the requirements of the food industry and each part is both dimensionally stable and highly elastic. The low-density material used in Filtroplast filter cartridges means that they are very light and because of the low density, easy to machine and weld. The porous structure means that they can be easily glued.
Colour: white
Schumasorb AK filter cartridges consist of chemically resistant and biologically inert carbon-bonded activated carbon. The universal suitability of the pure carbon filter-adsorbent is limited only by the known properties of activated carbon material. It is resistant within pH range 0 to 14 and has a maximum operating temperature in the presence of atmospheric oxygen of around 180°C.
Colour: black.
