Extend Coolant and tool life by an average of 27%, increase surface finish, and control bacteria with PRAB's line of paper bed filters. Standard paper bed filtration units are available with flow rates up to 130 gpm with different classes of filter media allowing for adjustments of micron clarity. Filters are suitable for applications of low to medium stock removal of ferrous and non-ferrous metals, as well as organic and inorganic contaminant such as glass, rubber and plastic. Drum-type models occupy one third the floor space and can process up to 500 gpm of fluids.

Features

  • Automated self-cleaning for continuous operation
  • Disposable paper or permanent filter media produces a positive barrier to remove solids from all free-flowing industrial process liquids
  • Filtering surface is automatically indexed only when necessary, saving costs for disposable media
  • Drum-type paper bed filters occupy one-third the floor space of a traditional paper bed filter, with flow rates up to 500 gpm.

Specifications: Paper Bed Filters

Standard paper bed filters use disposable media to filter between 5 and 130 gpm with tank capacities of between 20 and 220 gallons. Available with or without magnetic separation.

Stainless Steel Filters

The stainless steel paper bed filtration system is designed for the plastics manufacturing industry to provide efficient and economical separation of plastic pellets from water with flow rates up to 400 gpm. Higher rates available.


Vacuum Filtration

Mon-A-Vac™ Disposable Media

These filters utilize a vacuum chamber to draw dirty coolant through the disposable filter media. A vacuum system draws the dirty coolant through the filter media, causing solids and sludge to build up and cake on the media. Upon completion of the indexing cycle the filter returns to the normal operating mode. The clean tank is continuously and automatically refilled for the next index cycle.

Standard Vacuum Filter units are available with flow rates up to 4000 gpm. Custom designed vacuum filters are our specialty.

Features

  • Continuous media models eliminates down time
  • Permanent media models eliminate disposable media waste stream, adhering to ISO-1401 standards
  • Disposable media models offer various grades of media to meet fluid clarity requirements

Candle Filter - 1 Micron

FINE PARTICULATE OIL AND COOLANT FILTRATION
  • Engineered for oil filtration in EDM, tungsten carbide tool grinding, honing machine, and bearing grinding applications.
  • Membrane wafers capture grinding swarf at 1 micron.
  • Automatic air pressure back flush cycle reduces labor costs and increases process efficiency.
  • Swarf is purged into an external receptacle for easy collection and recycling.

Mon-A-Permanent™ Semi-Permanent Media

The Mon-A-permanent uses semi-permanent elements to eliminate disposable media and reduce operation costs. Back flushing the filter with clean coolant keeps the filter clean and eliminates the need for large volumes of air. The back-flushed solids drop from the filter element and settle into a tank where they are removed via an automatic chain dragout. The Mon-A-permanent requires minimal floor space and is completely self contained, simplifying maintenance and operation. Vacuum filter systems are offered in models, sizes, capacities, flow rates and media necessary to meet your needs.

Solid Bowl Centrifuges

Features

  • No special pumps are required for feed or discharge.
  • Suitable for centrifugal filtering of oils and water-based coolant.
  • Filter ferrous or non ferrous materials.
  • No Consumable media is required, adhering to ISO-14001 standards.
  • Available as a stand-alone unit, or can be incorporated into a customized centrifuge filtration system.
  • Flow rates up to 50 GPM.

Economical Models In Manual And Automatic

PRAB's line of Solid Bowl Centrifuges effectively separates solid from liquids in metal processing applications where removal of fines is important to recycle and reuse goals.

PRAB Solid Bowl Centrifuges provide high performance liquid separation for all types of particles, metallic, ferrous, non-ferrous, and non-metallic solids. Our centrifuges are available in both manually cleaned basket style, complete with reusable liner, and fully automatic self cleaning designs.

Magnetic Separators

Remove Ferrous Particles Efficiently and Economically

PRAB's line of magnetic separators employ high-intensity ferrite or rare earth magnets within a fully energized rotating drum to continuously remove ferrous particles from the flow of liquid. These systems are often used as a pre-filter to limit contaminants reaching subsequent filtration equipment. Magnetic Separators are well suited to processes where ferrous and non-ferrous contaminants are mixed with water based coolants or straight cutting oils.

Features

  • Available flow rates up to 315 gpm
  • No Consumable media - eliminates disposal media, waste stream, adhering to ISO-14001 standards
  • Continuous Operation - reduces machine downtime
  • Most units instock and can ship same day
  • Integrates easily with the Paper Bed Filter

Models

Depending upon your applications needs, PRAB and MSC offer three models of magnetic separators.

  • Standard Magnetic Separators Utilize ferrite magnets to remove ferrous particles
  • Super Magnetic Separators Utilize rare earth magnets with 8x (3000 gauss) the force of conventional ferrite magnets
  • 10T Super Magnetic Separators Utilize rare earth magnets with 10x (3600 gaus) the force of conventional ferrite magnets.

Rare Earth Magnets vs. Ferrite

Use rare earth magnets when the following conditions are met:

  • When large amounts of sludge accumulates within the machines coolant tank.
  • When the coolant being used is a Straight Oil Coolant (Honing Machines, Screw Machines).
