High Grade Filtration
and Vacuum Fluctuation

Solberg's Integrated Liquid Separator / Vacuum Filter solves these typical problems for the vacuum pump industry that traditional designs are unable to:

Typical Marketplace Need:

  • Vacuum Fluctuates: The vacuum level could not be sustained in a 3 chamber liquid separator system because ambient air is introduced to the system when it replaces the liquid that is removed.

Solution with Solberg's LRS / SRS Series:

  • Sustained Vacuum Level: When the liquid and slurry is removed; air does not enter the LRS / SRS which allows vacuum to be maintained.

Typical Marketplace Need:

  • High Grade Filtration Needed: The knock out pot style does not offer high efficiency filtration.

Solution with Solberg's LRS / SRS Series:

  • Filter Integrated into Separator: The LRS / SRS has multiple stages of filtration in one compact unit.

    -Integrated baffle
    -Preseparator strainer (SRS Style Only)
    -99+% efficient 5 micron (or better) filter element
ATEX and ASME Certified Filters
(upon request)

In July 2003, the new ATEX Directive 94/9EC (ATEX 95) was implemented Europe-wide to eliminate the possibility of explosions related to equipment used in potentially explosive gaseous or dusty environments.

Solberg became one of the first to be certified to service those industries in need of compliance with this directive.

In addition to being able to provide the SRS series with ATEX certification. Solberg is able to provide ASME Coded filters as well.

Applications & Equipment

Possible Uses

  • The integrated liquid separator is primarily used in air process systems where liquids such as water or solvents need to be separated before the air reaches the air pump. Pump contamination leads to oil degradation, premature pump filters and environmental problems.
  • Designed for the air stream of a vacuum pump but can be used in most applications where liquid separation is needed.
  • Food Packaging
  • Pharmaceutical
  • Chemical Processes
  • Vacuum Pumps & Systems
  • Metal Processing / Chip Processing
