Sanitary Straight-Through Pipeline Filters - Overview, Working Principle & Technical Parameters

Sanitary straight-through pipeline filters are mainly used in food processing, cosmetics, some chemical industries, and auxiliary services of the pharmaceutical industry to filter particles that may damage pumps, instruments, and other equipment. Due to their characteristics of compact structure, strong filtering capacity, and convenient maintenance, they are widely applied in fields such as beverages, pharmaceuticals, and dairy products.

Working Principle of Sanitary Straight-Through Filter

Sanitary filters are used to prevent solid particles in the filtered medium from entering subsequent pipeline equipment. When the medium enters a filter element of a certain specification from the filter inlet, the larger solid particles or impurities are retained in the filter element, and the filtered medium flows out from the outlet to meet the usage requirements. When the pressure difference across the filter exceeds the requirement or the filter element is damaged, it is only necessary to take out the filter element, clean it or replace it, and reinstall it for use.

This type of sanitary filter is divided into three structures: angle filter, Y-type filter, and straight-through filter.
