BECO CPS depth filter sheets are used for clarifying filtration in the chemical, cosmetic and food industries. The filter sheets remove particles of a coarse, crystalline, amorphous or gel-like structure perfectly. An extremely wide range of filtration tasks can be performed according to given specifications, even with highly viscous liquids.

Core features

  • High dirt-holding capacity for economic filtration
  • Differentiated fiber and cavity structure (internal surface area) for the widest possible range of applications and operating conditions
  • The ideal combination of filtration-active and adsorptive properties ensures maximum safety
  • Very pure raw materials and therefore minimum influence on filtrates
  • Comprehensive quality assurance for all raw and auxiliary materials and intensive in-process controls ensure consistent quality of the finished products

Special Depth Filters

  • High-purity cellulose
  • Low washable ions
  • No mineral components
  • Near complete catalyst separation at high flow rates
  • Near complete catalyst recovery

These special BECO depth filter sheets were developed for highest demands in the chemical industry. By using and selecting high-purity cellulose, the content of washable ions is exceptionally low. Since these depth filters contain no mineral components, there are only traces of iron and aluminum migration. Complete separation of catalysts at high flow rates is also possible using Eaton's BECO CPS depth filter sheets. Subsequent ashing enables virtually loss-free and nearly complete recovery of catalysts.
