CF20 Oil Skimmer Separator

Part #
CF20 Oil Skimmer

Maintain performance reliability while managing higher-than-average industrial fluid with Sentry's CF-20 CrossFlow Oil Skimmer Separator.

The CF-20 CrossFlow Oil Skimmer Separator ensures your equipment's longevity through a reinforced double-plant pack design that produces the same reliability as the standard Sentry CrossFlow. This tramp oil separator is built to maintain a non-clogging process while processing at a higher turnover rate. Using a gravity flow design and coalescence, the CF-20 separator can reduce tramp oils to less than 1% in a single pass. 

Applications that work best for this oil skimmer are:

  • water-soluble, semi-synthetic & synthetic coolants from machining and grinding
  • rolling and drawing coolants
  • alkaline wash waters
  • wastewater pre-treatment
  • aqueous quench pits
  • die casting mold release fluids

However, these oil separators aren't limited to just these applications. Any use where the separation of two immiscible fluids is required can benefit.


  • Reduce new fluid purchases by extending the life of your industrial fluids
  • Reduce waste volumes by 50% - 90%
  • Extend the bath life of parts washers & conserve water
  • Improve sump life, tooling, and parts quality in CNC operation
  • Reduce misting & improve machine cleanliness
  • Minimize tramp oil levels in large central coolant systems


  • Open Channel coalescing technology is low maintenance. The frequency of cleaning is a fraction of what is typically required.
  • Sloped bottom for easy removal of solids and sludge
  • Can be supplied with floating suction skimmers 
  • 304 stainless steel plate pack
  • Gentle flow through the system won't split weak emulsions and can be used with any coolant or cleaner.
  • The system can handle temperatures up to 250 degrees and flow rates up to 20 GPM based on chemistry.

Oil Separators

Sentry SmartSkim oil separators are designed to extend the life of your equipment by removing floating oil from various sources such as wash tanks and coolant sumps. From our compact V Series to the robust CF20 Model, Sentry oil skimmers are available for a variety of applications and operations.

Our team of oil separator manufacturers and engineers has developed an Open Channel coalescing technology that reduces plugging and is easy for manufacturers to maintain. These configurations were designed with various applications in mind, including water soluble, semi-synthetic & synthetic coolants, and are backed by years of industrial fluid separation experience.

Sentry SmartSkim oil skimmers are constructed to reduce waste volumes by up to 90%. This reduction comes from its long-lasting stainless steel construction and patented open channel backplate system. Removing plastic media, filters, or consumables of any kind ensures that uptime is maximized and cross-contamination is minimized.

Each product within this category is designed to meet your specific oil separation needs. If you have any questions, don’t hesitate to contact our team.
