Sanitary double-cartridge filter

A sanitary dual-filter refers to a filter that meets the stringent hygiene standards required by industries such as food, pharmaceuticals, and biotechnology, and is designed with a dual-unit structure. Its key feature lies in the provision of two parallel filtration units, enabling online filtering and switching, ensuring continuous filtration without the need for shutdowns to replace filter cartridges. This improves production efficiency and reduces downtime losses.

Sanitary dual-stage filters typically consist of a stainless steel housing, various filter elements, and sanitary valves. The shell material can be selected from A3, 304,304L,316, and 316L stainless steels, while the sealing materials can include PTFE, nitrile rubber, and oil-resistant asbestos gel. These material choices are based on their requirements for fluid hygiene and corrosion resistance.

The working principle of sanitary dual-filter is to assemble two single-tank filters on a machine base through a three-way ball valve and two ball valves, allowing for continuous operation without stopping during filter cleaning. In the food and beverage industry, it can be used to filter products such as fruit juice, beverages, beer, and milk, removing impurities and microorganisms to ensure product quality and safety. In the pharmaceutical industry, it is used for filtration in the manufacturing process, removing particulates and microorganisms to ensure the purity and safety of drugs. Additionally, in biotechnology, chemical, and electronic industries, sanitary dual-filters also play a crucial role.

The following factors should be considered when selecting a suitable sanitary double filter:

1. Filtering accuracy: choose the appropriate filtering accuracy according to the characteristics of the fluid and the purity requirements.
2. Flow: Select the appropriate filter model based on production scale and fluid flow.
3. Material: choose the appropriate filter material according to the characteristics of the fluid and hygiene requirements.
4. Interface type: Select the appropriate filter interface according to the interface type of the piping system.
5. Pressure: Select the appropriate filter pressure rating according to the working pressure of the system.

When using sanitary grade double filter, it is also necessary to pay attention to the regular cleaning of the filter core to prevent the deformation or damage of stainless steel wire mesh, so as to ensure the filtration effect and service life of the filter. At the same time, it is also necessary to pay attention to the maintenance and maintenance of the filter, timely replace the damaged filter core and components.
