FAUDI cartridge/candle filters are a very frequently used filter type across all industries. Regardless of whether they are applied for liquid or gaseous media, FAUDI candle filters are used in areas where fine to very fine impurities are to be filtered out of fluids. The cylindrical filter elements, which often remind a candle, give the filter its name. Apart from the cylindrical shape, there are almost no limits to the design of the filter cartridges. Application determines if filter cartridges are used for surface or depth filtration. The structural design and materials vary depending on the filtration task, dirt-holding capacity, medium or temperatures. Cartridge filters can be designed with regenerable or single-use elements. An adjustable modular system allows the FAUDI cartridge filter to be optimally matched to the process and the customer’s needs. This flexibility is also reflected in the design of the filter housings in terms of operating parameters, materials and their additional equipment.

how does a
cartridge filter

The medium to be filtered enters the dirt chamber of the filter through an inlet nozzle, flows through the upright or suspended filter cartridges from the outside to the inside and exits cleaned through the outlet nozzle. Carried impurities which particle size exceeds the filter fineness are retained on the surface or in the depth structure of the filter cartridge, depending on the filter type. The dirt particles retained by the filter cartridge cause an increase in the differential pressure between the dirty and clean sides of the filter. At a set differential pressure, the filter cartridges must be replaced or regenerated if possible.
