描述
Special porous silicate granules exclusively manufactured by Pall® are sintered with a siliceous bond to form Pall Aerolith porous ceramic, a material of the 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 Ceramic filter cartridges are 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.
