Filter Sheets

Dorsan's KAC series filter sheets have the great capacity to retain contaminants, as opposed to surface filtration in which these are retained by the mechanical action of surface screening. They round out the flavor and reduce astringency in some drinks.

The main advantage of depth filters is their high contaminant-retention capacity (as opposed to surface filters, in which contaminants are retained via the simple mechanical action of a surface sieve). In addition to the most typical 40×40 or 60×60 cm filter presses, we can supply any format with or without holes.

The special KAC series of sheets, with high carbon contents of up to 60%, retain fatty acids, decolourise and deodorise the product. They are also highly valued for rounding off taste and reducing astringency in certain beverages.
