Hydrocyclone Fluid Filtration System

High-efficiency, Media-Free Separation of Solids from Coolants and Process Fluids

PRAB’s Hydrocyclone fluid filtration system is an efficient, maintenance-free solution for removing up to 90% of 20 micron and larger solids from machining coolant, wash water, and other process fluids—without the use of filter media. Designed for metalworking and industrial operations, this media-free cyclone separator supports sustainable fluid management by reducing maintenance downtime, improving fluid life, and lowering operational costs.

Key Benefits:

  • Media-Free Operation: Eliminates the cost and disposal of filter paper or cartridges. hydrocyclones use water to separate coolant from contaminants
  • High-Efficiency Solid Removal: Separates abrasive particles and solids as small as 20 microns.
  • Minimal Maintenance: No moving parts or media to replace; the system requires little supervision.
  • Compact & Modular Design: Easily integrates with existing central systems or machine tool sumps.
  • Improves Coolant Performance: Keeps coolant cleaner, extending tool life and improving part finish.
  • Supports Compliance & Sustainability: Reduces waste generation and supports ISO 14001 goals.

How It Works:

PRAB Hydrocyclones use centrifugal force to spin fluid and solids inside a conical chamber rapidly. Heavier particles move to the outer wall and are forced downward into a collection chamber, while clean fluid is returned for reuse. This continuous, pressure-driven process ensures uninterrupted operation and consistent results—ideal for high-volume CNC machining, tumbling, deburring, and grinding operations.

Common Applications:

  • Machining centers (aluminum, steel, cast iron)
  • Tumbling and vibratory deburring operations
  • Parts washers and rinse stations
  • Grinding, honing, and polishing systems
  • General plant wash water systems

Performance & Integration:

  • Handles a wide range of flow rates (customizable per application)
  • Suitable for standalone operation or as a pre-filtration step before ultrafiltration or centralized coolant recycling systems
  • Frequently combined with PRAB’s Guardian Coolant Recycling System or Ultrafiltration Systems for complete fluid recycling
  • Water soluble machining coolant
  • Filtration of ferrous and non-ferrous materials:
    • Carbon steel
    • Stainless steel
    • Chrome
    • Copper
    • Aluminum
    • Non-metallic materials such as glass and grinding wheel grit
