Dairy Conical Filters
What is a Dairy Conical Filter?
A Dairy Conical Filter is a sanitary-grade inline filtration device used in dairy, food, and beverage processing lines to remove particulates, curd residues, or foreign solids from liquid products. The filter consists of a fine perforated or mesh stainless steel cone installed within a housing, allowing clean and uninterrupted product flow while maintaining hygiene.
These filters are highly compatible with CIP (Clean-in-Place) systems, making them ideal for hygienic and high-volume applications.
Asaid Steel Industries is a trusted supplier of Dairy Conical Filters, offering robust, food-grade SS 316L constructions that meet international sanitary standards.
