BOPP manufactures a comprehensive and diverse range of medium, fine and ultrafine 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. Dependent upon requirements, the meshes 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.

 

Properties

BOPP FI stainless steel filter meshes are unique in combining a number of important characteristics.

  • Optimum flow rates
  • Precise aperture size distribution
  • High levels of stability
  • Rigidity
  • Advanced abrasion resistance
  • No particle detachment
  • Easy to clean
  • Good plasticity
  • Chemical and thermal resistance
  • Smooth surface structure
  • Advanced reliability

Availability

  • Mostly produced using stainless steel DIN 1.4306 (AISI 304L), and DIN 1.4404 (AISI 316 L), sometimes using other alloys such as Monel, Hastelloy, DIN 1.4539 (AISI 904 L), Titanium etc.
  • Bespoke specifications also available
  • Standard widths 1020mm and 1220mm, ex-stock or at short notice from current production runs, other widths available on request
  • Standard roll lengths 15m and 30m according to specification. Cut sections also available in all sizes and shapes.

For challenging applications in filtration, sintered steel meshes are now increasingly used instead of filter meshes. Here, a selected range of meshes are bonded together using heat and pressure. This effectively combines the performance advantages of each individual mesh layer and results in optimisation of the filtration process. The resultant bonded mesh enables the finest filtration to be achieved, but thanks to the robust mesh structure, the medium is resistant to physical loading. The smooth surface also offers advantages for the cleaning process when backwashing.

 

Properties and advantages

  • Defined finest aperture size and regular pore distribution
  • Extremely robust, resistant to mechanical and thermal loading (up to 600oC dependent upon alloy), long service life, therefore reduced downtime
  • High flow rates, selectable flow resistance
  • Optimum backwashing capability, advanced reliability in terms of backwashing pressure
  • Reduced loading of the filter medium in pulsation
  • Consistent product quality, advanced levels of corrosion resistance with the use of noble metals such as stainless steel, Hastelloy, Inconel etc.
  • Wide range of combinations up to 1000 layers possible
  • Disk sizes up to 1200 x 1200mm possible without welding
