Field of application of filter elements 

Filter elements are the core of each BOLLFILTER and individually adapted for the diverse fields of application of our customers. Whether in the

• chemical
• automobile industry
• paper industry
• power stations
• steel works, mining or
• in oil and gas production

due to the use of the optimum suitable type of mesh, the protection function of the filter is ensured at all times and the defined particles of solids are reliably retained.

Structure of the filter element

A filter element consists primarily of a support body and the filter mesh, which is pulled over it. Different constructions, such as star sieves, filter cartridges or filter candles, provide different large filter areas. Due to the optimum combination of the core components, the required cleaning effect can be attained for every medium.

Composition of the Filter elements

Depending on the type of filter and filtration performance required, diverse meshes and materials are used for the filter elements. The filter material as sieve insert or filter candle consists of linen, stainless steel (CrNiMo steel) or polyester in different widths of mesh, so that one of the requirements of the appropriate sphere passage and the filter fineness required is ensured. In addition to the maximum attainable filter fineness being dependent on the filter medium, so are the temperature, resistance to pressure and the service life. Whilst stainless-steel wire mesh can be cleaned often and used over a long period of time, superfine disposable cartridges with a filter medium made from fleece, must be replaced after use.
