Filtration and Separation

BOPP manufactures a comprehensive and diverse range of medium, fine and ultra-fine filter meshes. These are produced using state of the art weaving machines, in clean and air conditioned halls, to the highest levels of quality and reproducibility. A growing number of sintered meshes are now available to meet the challenges of increasingly demanding applications. These consist of two or more layers of mesh, crafted into laminates using heat and pressure. Dependent upon requirements, both meshes and sintered products can be converted into dimensionally accurate components and semi-finished goods, with individual items carefully worked by hand and series production either partly or fully automated using special machinery designed expressly for this purpose.

General properties for the filtration industry

  • Raw materials compliant with the highest international standards
  • Manufactured using state of the art production processes
  • Precise aperture size distribution
  • Uniform surface area for improved processes and cleaning
  • High levels of abrasion resistance, no particle detachment
  • Developed using many years of experience in filtration
  • High value filtration results thanks to professional manufacturing

The most important characteristics for filtration process requirements are

  • Material parameters
  • Loadings in use: mechanical, thermal, chemical
  • Compression ratios
  • Flow rates
  • Mass, dimensions, design
  • Installation location
  • Accessories
  • Cleanliness requirements
  • Ergonomics in use
  • Standards requirements

The most important considerations to meet demanding filtration requirements are

  • Correct choice of the most suitable materials
  • Deciding between filter mesh or sintered product
  • Wire diameter, especially for filter meshes
  • Aperture count, mesh count
  • Filter fineness
  • Mesh style, geometry or laminate type
  • Tensile yield point
  • Workability
  • Binding method

Important notice to our current and future customers:

G. Bopp + Co. AG (“Bopp”) and even their existing customers have recently noticed that online offerings of products which look similar to those of Bopp and declaring them as “Bopp” products are increasingly being introduced on online purchasing platforms. There is no doubt that these offerings infringe Bopp’s trademarks, violate unfair competition (and other) laws and seriously deceive the market participants.

Bopp have reacted and undertaken respective measures to defend and protect their rights. Considering the enormous number of violators, it seems inevitable that this process will take longer than Bopp desire.

In the meantime, Bopp would like to emphasize the following:
Products manufactured by G. Bopp + Co. AG in Zurich, Switzerland are exclusively available from its subsidiaries in Switzerland, Germany, England, Italy, Sweden, USA, Korea and China and the nominated representations.

G. Bopp + Co. AG are one of the world’s leading producers of precision woven wire meshes providing their high-quality products to market leaders in the high tech, pharmaceutical, chemical, aeronautics, plastic, glass, ceramics, mechanical engineering, paper, environmental technology and even space travel (www.bopp.com).
