Special porous silicate granules exclusively manufactured by Pall® are sintered with a siliceous bond to form Pall Aerolith porous ceramic, a material of homogeneous composition. This porous Aerolith ceramic consists mainly of crystalline and amorphous silicates.
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 can be used in depth filtration applications of up to 500 °C (932 °F).
General Information
- Porous Aerolith ceramic elements 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 can supply. Consideration must be paid to operating temperature and chemical resistance.
- Pall can supply a variety of element fixing systems.
