Vacuum Filters
Vacuum filtration design replaces costly and complex hydraulic or air closure systems that typically seal flatbed pressure filters.
Low Volume Filters: gravity bed, cartridge, magnetic roll separators, and centrifuge
Media Vacuum Filters: rolled paper to achieve down to 10 microns filtration and 2,000 GPM flow rate
Hydroflow CBN Series Vacuum Filters: specifically designed to handle heavy oil associated with CBN machining
Vacuum filtration design replaces costly and complex hydraulic or air closure systems that typically seal flatbed pressure filters
- Innovative vacuum pump handles clean coolant only, drawing dirty fluid through the media, eliminating the wear associated with pumping dirty coolant
- Features high flow rates (up to 100 gallons per minute or 378 liters per minute)
- Conveyorized dirty tank and filter section in one assembly eliminates the settling, backflow, and balance problems associated with pressure filters
- Provides complete removal of solids from the dirty tank and removes settled solids
- Automatic regeneration uses a small clean tank to provide uninterrupted flow of clean fluid to the point of use
- By introducing only a small section of new media into the filter section, the Hydroflow Vacuum Filter eliminates the filtration spikes caused by pressure filters that index the entire filter bed
Star Filter Central Filtration System
The Star Filter is a patented, automatic filtration system using a centrifugal pump to draw coolant through a permanent media element for multi-machine, complete factory filtration requirements.
- Nominal filtration of 1 to 3 microns
- For extra-fine two-stage filtration using cellulose media with permanent filter
- Water or oil-based coolant filtration
- Patented Star Filter® for flow rates 250 to 10,000 GPM
- Large filter surface area; regeneration of entire surface
- Easily remove individual elements designed for fine grinding coolant filtration application
- Automatic cycle regeneration and pre-coat
- Drag out conveyor automatically removes solids
- Complete project management: piping, sump tanks, installation assistance
- PLC controls and operator interface with touch screen graphics
Application
- Grinding, machining: drilling, milling, boring, and turning
- Aerospace alloys, superfinishing, carbide, glass, cast iron, and aluminum
- Centerless, ID/OD, surface and form grinding
- Creep feed grinding
- CBN grinding/superabrasive machining
- CNC machining
Deep Bed Gravity Filter
Designed to remove solids from cutting fluids in machining and grinding operations, the Hydroflow Deep Bed Gravity Filter, with increased liquid depth, creates additional head pressure to provide improved filtration versus typical gravity bed filters.
- Heavy-Duty construction prevents bed flexing, cracked welds, or structural failures
- Ideal for individual machine tools with water-based coolants
- Wide seal edges and long path of media ensures tight seal eliminating dirty coolant by-pass
- Gasket and bolted clean-out port provides easy flushing and cleaning
- Filtration performance to 2-30 microns or as low as 10 microns with cartridge filter
- Chainless design eliminates chronic issues that are typical with standard flat-bed filters
- Steep deep bed design creates drier media
