Coolant Filtration - Microtech Drum Filter

The MicroTech Drum Filter (MDF) is a permanently-submerged media vacuum filter designed for cleaning many types of coolants used in grinding & machining. The MDF is a two-stage filter system combining a solids settling tank and a cellulose depth filter into one system. The heart of the system is the MicroTech Drum Filter element. Its unique design provides exceptional filtration performance and reliability. The Microtech Drum Filter has been designed to operate between a choice of three grades of cellulose pre-coat – 1, 5, or 10 micron filtration. For course grinding or machining projects requiring only 20/30 microns the filter can be used without cellulose as a media-free “self-coat” filter.

Coolant filtration

MDF

  • Uses cellulose to form depth filtration preventing surface blinding common to roll media filters.
  • Has a permanent-media sealed filter element without moving roll media that can rip or bypass solids.
  • Has 30% more filter area than roll media filters with lower fluid velocity providing longer filter cycles.
  • Coats all the filter area for low fluid velocity, the media filter advances a few inches with high velocity.
  • Offers two stages of filtration - gravity settling and depth filtration.
  • Has no large, hard to clean vacuum box like those found in roll media filters.
  • Has an element backwash for the used dirty cellulose with no messy and costly disposal of dirty roll media.
  • Has surface flushing moving the floating swarf to the ramp for dragout removal unlike the roll media filter.
  • Filter area can be expanded in the field for different applications not possible with flat bed media filters.
