Pall Aerolith Ceramics

Summary

Product identification

Pall Aerolith® Ceramic Products are made from special porous silicate granules, exclusively manufactured by Pall, and sintered with a siliceous bond. This material forms a homogeneous porous ceramic composed mainly of crystalline and amorphous silicates.

Key characteristics include:

• High porosity and large internal surface for high storing capacity for particles and liquids.
• Labyrinth structure for excellent separation efficiency at a simultaneously very low increase of differential pressure.
• Variety of configurations for depth filtration applications.

Operating limits

• Maximum Temperature Resistance: Up to 500 °C (932 °F)
• Chemical Resistance: Resistant to most acids, saline solutions, and organic solvents (liquid or gaseous). Resistant up to pH 9 in the alkaline range. Users are responsible for verifying compatibility with specific end-use conditions.

Applications

Cylinders and Flanged Candles:

• Particle filtration for Liquids: Acids, water, and alcohol
• Particle filtration for Gases: Process gases, air, sewer gas, natural gas, and liquid gas
• Coalescer: Compressed air, nitrogen, and carbon dioxide
• Storing Media: Water, colour, and ink
• Aeration Element: Drinking water, mineral water, and fish ponds
• Vacuum Lance: Retention of fire extinguishing powder

Plates:

• Aeration Element: Drinking water, mineral water, and fish ponds
• Nutsches: Mud thickening

Mechanical / Hydraulic

The elements are available in various types, including Cylinders, Flanged Candles, and Plates. Dimensions vary significantly by part number. Examples include cylinders with outer/inner diameters (Do/Di) of 40/20 mm, 60/40 mm, and 70/40 mm, and lengths up to 1000 mm. Plates are available with dimensions like 250 mm x 250 mm x 50 mm. See the official PDF for exact tabulated values of specific part numbers, dimensions, areas, and weights.

Graphs illustrating Flow vs. Differential Pressure for both air flow (T = 20 °C (68 °F)) and water flow (T = 20 °C (68 °F)) are provided in the official PDF, showing performance for AE 10, AE 20, and AE 30 types.

General Information

• Porous Aerolith ceramic elements can be machined using hard metal tools.
• Ceramic elements require careful handling.
• 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.
