Sentry CrossFlow Oil Skimmer

Part #
Sentry CrossFlow

Extend the life of your industrial fluids and streamline your waste processing operations with regular tramp oil skimming and separation.

Sentry’s easy-to-maintain SmartSkim CrossFlow Oil Skimmer ensures your equipment's longevity and team safety by removing free-floating tramp oils from wash tanks, coolant sumps, central coolant systems, and other industrial processes. Based on its gravity flow and coalescence design, the CrossFlow oil separator can reduce tramp oils to less than 1% in a single pass. 

Sentry’s open-channel, reduced-clogging oil separator reduces the need for maintenance and enhances longevity by eliminating plastic consumables. 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
  • Manages environmental waste, bacteria levels, and associated odors


  • 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
  • Automated system for continuous operation
  • 304 stainless steel plate pack 
  • Gentle flow through the system won't split weak emulsions or remove additives
  • The system can handle temperatures up to 250 degrees and flow rates up to 10 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.
