ALUCEL® High Surface Area Alumina Filters

ALUCEL® High Surface Area Filters are the newest generation of high performance advanced ceramic filters for non-ferrous foundries. For a given filter bowl size, the unique patent of an undulating geometry increases the surface area available for inclusion capture. This eliminates the need for casting line operators to disturb the metal over the filter or to tap the filter bowl prior to the end of a cast causing possible inclusion release.

With approximately 30% higher surface area, the filter allows greater ease of priming and better flow rate, enabling the use of smaller pore size filters for more effective removal of smaller non-metallic inclusions.

Composition

- High purity aluminum oxides

Characteristics

- Available in all standard industrial sizes: 5x5x1.5'' to 23x23x1.5''

- Standard Pore Sizes (ppi): 20A, 30A, 40A, 50A

- Alucel's superior strength properties allow us to produce it in 1.5“ thickness versus the standard 2" of comparable filters

- Side walls can be either tapered to your specifications or produced with a straight wall gasket design. Straight wall design can increase sealing pressure up to a factor of four, creating a more secure seal.

- Also be custom manufactured to your specific dimensions, chemistry and flow rate requirements  

Advantages of New Wave® high surface area design:

- Fewer aborted drops; fewer runs where you have to watch your casting rate in case the filter backs up.

- Ease of priming

- Potential for running finer pore sizes and improving metal cleanliness with minimal sacrifice in flow or operation

- Special processing techniques result in fewer blocked pores.

- Fully sintered for strength, greater thermal shock resistance and less "snow" than phosphate bonded filters

- Less temperamental filters for preheating

- The correct physical and mechanical dimensional properties meet the most stringent specifications and will yield the optimum results for your application .

ALUCEL® alumina filters are a highly porous, open-cell sintered ceramic material. Due to the absence of pore blockages, a more open structure is obtained within a specific pore size. This allows greater ease of priming and better flow rates, thus the ability to utilize filters with smaller pore sizes. The finer pore size allows for higher filter efficiency and more effective removal of smaller, non-metallic inclusions.
