Aerolith® Material

Special porous silicate granules exclusively manufactured by Pall Schumacher, are sintered with a siliceous bond to form a material of homogeneous composition named Aerolith. The porous Aerolith ceramic consists mainly of crystalline and amorphous silicates and the colour is white.

Due to high porosity and the large internal surface, the porous Aerolith ceramic products offer a high storing capacity for particles and liquids. The labyrinth structure leads to an excellent separation efficiency at a simultaneously very low increase of differential pressure.  Porous Aerolith ceramic is distinguished by the large variety of configurations, and is used in depth filtration applications up to 500° C.

General Information

• Porous Aerolith ceramic products can be utilized in the food and beverage industry in accordance with the German Foodstuffs and Consumer Goods Act and according to the European Directive 89/109/EEC – referring to directives 2002/72/EC and / or 84/500/EEC and their amendments, as appropriate.
• Porous Aerolith ceramic is approved for the utilization in drinking water according to German regulations DVGW W270 and the KTW recommendation.
• Porous Aerolith ceramic can be machined using hard metal tools.
• Ceramic elements are to be handled with care.
• Elements can be easily glued using commercial glues which Pall Schumacher can supply. Consideration must be paid to operating temperature and chemical resistance.
• Pall Schumacher can supply a variety of element fixing systems.
