Full Flow Coolant Filtration for Fines & Debris

The Purge Filtration System

The Purge provides constant, full-flow coolant filtration. It prevents small chips and fines from entering the machine tool's coolant tank, where they can clog screens, nozzles and lines, and cause coolant starvation of the flood pumps and high pressure coolant pumps.

PURGE V2 Small

The Purge circulates dirty coolant through it's pressurized debris collection system where filters catch large debris before returning the clean coolant to tank. Filtered coolant enters the coolant tank faster than it's sent to the machine tool, so the clean side of the tank always stays full. Constant back flow ensures filter screens never dam up.

  • Use with oil or water-based coolant
  • Filters variety of materials
  • Holds up to 20 gallons of debris
  • Quick, ergonomic filter changes - no tools required
  • Filters can be changed while the machine tool is running
  • Eyelevel-mounted PLC display

How Purge Works

The video below explains more in depth how the Purge effectively filters coolant.

Purge Pro

The Purge Pro is designed to filter smaller fines at lower flow rates compared to the Purge SD.

Purge Pro Specs:

  • 30 - 80 GPM Flow Rate
  • Filters fines up to 1/4" in diameter
  • 3HP Configurable Mounted Pump
  • 4 Pressurized Filter Vessels
  • 20 Gallon Total Filter Capacity
  • Eyelevel-Mount PLC Display
  • LED Status Indicator Mounted High for Visibility
  • No-spill Drainable Filter Deck

Purge SD

The Purge SD is designed to filter larger fines while running at higher flow rates compared to the Purge Pro. 

Purge SD Specs:

  • 40 - 80 GPM Flow Rate
  • Rugged cast pump w/ 3HP inverter duty motor
  • Filters fines up to 1"
  • 4 Pressurized Filter Vessels
  • 20 Gallon Total Filter Capacity
  • Eyelevel-Mount PLC Display
  • LED Status Indicator Mounted High for Visibility
  • No-spill Drainable Filter Deck

Benefits of Full Flow Filtration

  • Clean coolant lasts significantly longer
  • Less wear & tear on machine and components
  • Greatly extend time between tank cleanouts
  • Prevent unexpected coolant related shutdowns
  • Overall cleaner machining environment
  • Improved part quality and tool life
  • Excess reverse flow prevents chips from building up on the screens
  • Customer can continue to run machine tool while changing purge filters
  • Hour counter can be implemented to develop filter change schedule
  • Provides constant flow of clean coolant to prevent starvation of flood and high-pressure pumps.
