Filtering to 10 microns with automatic vacuum filtration

Share This Post

Eriez Hydroflow Automatic Vacuum Filtration Systems work continuously with minimal operator attention and provides consistent solids separation, maximum coolant life and increased productivity for the metalworking industry.

 

This unique design provides positive filtration levels to 10 microns because of an innovative method that seals the filter media to prevent solids bypass. The system also has the capacity to effectively handle flow rates up to 2,000 gallons per minute (7,570 liters per minute).Eriez Hydroflow Vacuum Filters, with their specially design features, have multiple advantages over conventional flat bed pressure filters, cyclonic and pre-coat pressure filters:

  • The vacuum filtration design itself replaces costly and complex hydraulic or air closure systems that typically seal flat bed pressure filters.
  • The innovative vacuum pump handles clean coolant only, as it draws the dirty fluid through the media, eliminating the wear associated with pumping dirty coolant.
  • Conveyorized dirty tank and filter section in one assembly eliminates the settling, backflow and balance problems associated with pressure filters.
  • It provides complete removal of solids from the dirty tank and removes settled solids.
  • Automatic regeneration uses a small clean tank to provide un-interrupted flow of clean fluid to the point of use. By introducing only a small section of new media into the filter section, the Vacuum Filter eliminates the filtration spikes caused by pressure filters that index the entire filter bed.
  • Hydroflow Vacuum Systems do not use air for backwash or to dry the solids discharge, eliminating the need for additional air compressors, accumulators or mist collectors.

Eriez also offers the Hydroflow CBN Series Vacuum Filters, specifically designed to handle heavy oils, aerated by very high pressure (up to 1,000 PSI) and the blinding and short cycling associated with CBN machining.

The CBN Series features high flow rates (up to 100 gallons per minute or 378 liters per minute) at high pressures (up to 1,000 PSI). One advantage of this system is the positive displacement air-operated filter pumps, which are extremely effective on highly-aerated heavy oils. Special filters are available with refrigeration systems mounted on top of the filter.
