Eriez HydroFlow Media Vacuum Filtration

Eriez' HydroFlow Rolled Media Vacuum Filters are fully automatic systems capable of filtering to 8-10 microns through an innovative seal preventing solids by-pass.

These filters provide continuous service with minimal operator attention and a consistent level of solids separation, maximizing coolant life and increasing productivity.

These general-purpose filters are ideal for:

  • Grinding and Machining
  • Creep Feed and CBN grinding
  • All types of alloys
  • Filtering light oils or water-soluble coolants

Features:

  • Restrictive solids by-pass vacuum design
  • Smooth proprietary conveyor system
  • Automated coolant make-up system
  • Rugged construction
  • Coolant delivery systems

HydroFlow Advantage

The HydroFlow Vacuum Filter provides significant advantages over conventional flat bed pressure filters, cyclonic and precoat pressure filters.

 

Low Cost, Ease of Operation

Vacuum Filtration eliminates costly, complex hydraulic or air closure systems used to seal flat bed pressure filters.

Reduced Wear

Vacuum filters pump "clean" coolant only eliminating the wear of pumping dirty coolant.

Packaged System

The Vacuum Filter is a packaged system combining a conveyorized dirty tank and filter section into one assembly, eliminating the settling, backflow and balance problems associated with pressure filters.

Automatic Regeneration

A small clean tank provides uninterrupted flow of clean fluid. By introducing only a small section of new media into the filter section, the Vacuum Filter eliminates the filtration spikes of pressure filters that index the entire filter bed.

Conveyorized Dirty Tank

Continuous removal of solids and settled solids from the dirty tank.

No Backwash

No air is used for backwash or to dry the solids discharge, eliminating the need for additional air compressors, accumulators or mist collectors.

Principle of Operation

Eriez' HydroFlow Rolled Media Vacuum Filters feature a proprietary vacuum box design that provides a superior seal and better fluid filtration. Eriez offers three RMVF models and a range of media options to provide the right combination of capacity, throughput and filtration.

"A" Series Low Volume Rolled Media Vacuum Filter

Eriez' HydroFlow "A" Series is an entry level rolled media vacuum filter providing economical fluid filtration for a single machine or small cells. This filter handles flow rates from 40 to 360 gallons per minute while delivering filtration from 8-10 microns. Each model features fully automated controls to minimize operator involvement and ensure continuous flow of clean fluids to the machine. Eriez offers a wide assortment of accessories to meet your specific fluid handling needs.

Features:

  • Flow rates from 40 to 360 GPM
  • Filtration to 8-10 microns
  • Inexpensive with low operating costs
  • Quick and easy sludge disposal
  • Compact size with low inlet height

 

"B" Series Medium Volume Vacuum Filters

Eriez' "B" Series HydroFlow Vacuum Filters typically serve a single machine or a medium cell. Models range from 120-900 gallons per minute and can be outfitted with gravity or high-pressure coolant delivery systems.

These mid-range filters feature automated coolant make-up systems, restrictive by-pass vacuum box design and rugged conveyor system for smooth continuous operation.

Features:

  • Restrictive solids by-pass vacuum design
  • Smooth proprietary conveyor system
  • Automated coolant make-up system
  • Rugged construction
  • Coolant delivery systems

"C" Series High Volume Rolled Media Vacuum Filter

The Eriez HydroFlow "C" Series rolled medium vacuum filters are larger, robust filters designed to support multiple machine tools. These large central systems filters are constructed with heavy duty chain and flight conveyors to handle heavy loads of chips and swarf. Vacuum chambers are constructed to maintain high transport velocities. Multiple pumps provide filtered coolant flow to cleanliness and pressure requirements for meeting the demands of precision metalworking processes.

Features:

  • Special highloft media increases cycle time in blinding applications
  • Sized for individual machines or small cells in either gravity or pumped entry designs
  • Optional top-mounted refrigeration unit conserves floor space
