Product Description

The range of Innovacera porous ceramic filters are made from aluminum oxide and silicon carbide. The strong, uniform porous

ceramic has 40-50% open porosity with a tortuous pore structure and is available in pore sizes ranging from 1 to 120 microns.

Monolithic, single grade, aluminum oxide porous ceramic is available in 1, 15, 30, 50, 60, 80, 100 and 120 micron pore sizes.


Aluminum oxide is the most standard material, with a density of 2.2 g/cc, and has a maximum operating temperature of 1400 °F

(800 °C).

The range of porous ceramic products includes:

• Membrane and monolithic tubes

• Discs

• Plates and other components made from aluminum oxide and silicon carbide where tightly controlled pore size and porosity is

critical.
 

Specifically tailored techniques include:

• Spraying

• Brushing

• Backwashing

• Oven firing

• Dilute acid cleaning

• Solvent cleaning plus steam

• Ultrasonic cleaning

Porous Ceramics Applications

• Used in tough applications to replace porous metal or as an alternative to plastic or fabric media

• Cleaned and reused using a variety of methods depending on the contaminant to be removed
