Fairey industrial ceramics, uk, manufactures porous ceramic media and ceramic membranes that are supplied by superflo filters. These are useful in applications like filtration, aeration and diffusion, crossflow micro filtration, etc. These products have controlled pore size distribution, usable for abrasive applications, can be backwashed, and are steam sterilizeable. Ceramic products are normally chemical inert and can handle acidic gases. Since porous ceramics remain stable at elevated temperatures, they come to operate temperatures up to 100&176;c. The maximum temperature at which they are usable, is determined by their composition and their firing temperature during manufacturing. The materials are coralith,pyrolith, microlith and celloton. Each has its unique characteristics and capabilities. They find typical applications in hot gas filtration, precoat filtration, coalescing filtration, process filtration, dust and fume filtration, and compressed air filtration.
