Custom filtration systems allow you to clean and condition your system's fluid regardless of the system's operation or location.  Examples of some systems include mobile filter carts, fluid transfer carts and high flow filter skids.

Some filtration characteristics include:

  • Particulate filtration down to 1 micron absolute.What is Beta Ratio?  (PDF, 1.1MB)
  • Filter 100% of "Free" water.  (See the fluid vacuum dehydrator section below regarding dissolved water removal).
  • Optional integrated particle counters and water sensors report fluid quality in real-time.
  • Mobile filter carts can easily be moved from system to system for regular conditioning.
  • Custom layouts and enclosures for improve accessibility and maintenance.

Fluid Filtration and Conditioning

Fluid vacuum dehydrators provide total fluid conditioning by removing particulate; 100% of free water and gases; and dissolved water to 20 PPM (.002%).  Dehydrators can greatly reduce operating and replacement costs while extending fluid life and can be moved from one system to another, or installed permanently for continuous conditioning.

Fluid Testers and Monitors

Contamination Testing

Advanced Fluid Systems can help you find a particle counter that accurately measures fluid cleanliness and dissolved water in your hydraulic fluid.

Particle counters are available as portable test units or can be installed permanently for continuous monitoring.

Particle Counters are available with LCD, thermal paper and computer terminal interfaces for quick, easy output.
