Filter Elements for Oil Mist, Emulsion Mist and Aerosols

  • Excellent degree of separation
  • Extremely large storage capacity
  • Low filter pressure loss
  • Compact design
  • Long service life
  • Replaceable pre-filter


Separation of liquid particles from the air, which arise in machining processes, using the coalescence principle.

CNC machining centers

During machining, oil mist or oil smoke occurs in very different concentrations and with very different particle sizes. Our filter elements separate the entire range according to the coalescence principle.


Vapors and fumes released during the hardening of metals are completely separated out to keep the air in the work area clean.

Metal forming

Efficient separation of coolants and lubricants, which evaporate as oil mist when metals are formed, to protect the health of employees.

Wire drawing

The high degree of separation of our filter elements ensures the separation of even very fine particles.

For the filtration of oil mist, emulsion mist and aerosols R + B Filter supplies pleated filter cartridges and pleated filter cassettes. They are storage filter elements with a filter medium specially developed for these applications.

A removable coarse filter serves as a pre-filter. This is where most of the particles are stored. The remaining particles are stored in the fine filter.

  • Multi-stage: specially developed for separating liquid particles
  • High absorption capacity thanks to several filter levels
  • Degree of separation of 99% for particles with a size of 1 to 2,5 μm


  • Design: filter cartridges or filter cassettes
  • All standard dimensions and mounting systems can be selected
  • Maximum operating temperature 80 ° C
  • Metal parts aluminum, galvanized steel
