These filters are particularly suitable for the casting of non- and low-alloyed types of cast steel. They can also be used in conjunction with most of the other types cast steel without problems as long as the carbon content is about 0.15%. They have an extremely high strength and temperature resistance. They are available in all standard sizes and porosities.

The flow capacities are depending on customers process parameters and therefore the values only can be recommendations.

The filters in the table above are standardized. Special sizes are available with variations in dimensions from 35 to 300 mm and up to a thickness of 50 mm.
