Graver Technologies, LLC introduces TurboGuard, its technically improved 6 inch (152 mm) high-flow filter for the utility market. Graver is the world’s largest supplier of condensate system filters and components and has been manufacturing precoat and non-precoat septa for condensate systems for more than 50 years. Graver is the consistent technology innovator with more than 40 patents and numerous technical advances for condensate and high purity water applications.

Graver’s family of TurboGuard High Flow Filters will provide superior CRUD removal upstream of deep bed demineralizers. TurboGuard High Flow Filters may also be used following ion exchange beds as a resin trap,
or as highly efficient pre-filters before membrane systems. Graver’s TurboGuard line of filters are manufactured in the USA at Graver Technologies manufacturing plants, under an ISO-9001 (2000) quality system.

Graver’s TurboGuard High Flow Filter integrates a number of improvements over currently available elements. With the most experience of any supplier in condensate applications, Graver can access more than 50 years of experience when improving fundamental filtration in condensate and high purity water applications.

AEGIS® TurboGuard® Pre-Filters

  • Flow is from the inside core to the outer pleats
  • TurboGuard Filters are wrapped in a one-piece extruded outer cage preventing media migration during inside out flow
  • TurboGuard’s one-piece extruded outer cage allows for easier maintenance and removal after use
  • One-piece molded end caps, including molded-in bail for secure handling during installation and removal
  • Quad Seal gasket system to provide maximum sealing surfaces
  • Highest dirt holding capacity – approximately 25 lbs (11.5 Kg) before removal is required
  • Low pressure drop – less than 0.2 bar in service at specified flow rate
  • Optimized media surface area allows full use of installed media area – not blocked off by media “squeezing

Typical Applications

  • Pre-filter for protection of Deep Bed demineralizers
  • Pre-filter for protection of RO membranes
  • Retrofit OEM high flow large geometry filter housings

Power Generation Systems — The Right Septa Choice

High Flow Series Filter Cartridges

Large Geometry Pleated Filters for High Flow

Graver High Flow Series filters feature a larger geometry to handle higher flows with fewer filter elements. The result is much faster, easier filter changeouts. In addition, the inside to outside flow allows for excellent dirt holding capacity, extending the time between filter changeouts.

Filter housings are also available and because of the filters high flow and dirt holding capacity, smaller systems are possible, reducing upfront capital costs.

High Flow Series Features – Benefits

  • 6” diameter, large geometry for high flows
  • Absolute retention ratings from 1 to 100 microns
  • Capable of flow rates up to 500 GPM in a single 60” element
  • FDA listed materials of construction
  • Inside-out flow retains contaminant even during change-out
  • Multi layer pleated construction with optimized surface area
  • Outer cage prevents media extrusion problem experienced with some competitive offerings
  • Unique Quad Seal gasket provides maximum seal integrity
  • Retrofits competitive high flow filter housings
  • Thermally bonded construction

TPM™ Titanium Filter Series

Titanium Porous Metal Technology TPM series filters are porous titanium filters designed for applications involving heat, gases, aggressive chemicals, cryogenics or polymers.

Made from titanium powder, that is sintered to form a rugged, fixed pore structure, TPM filtersare made to withstand temperature extremes, high pressuresand repeated cleaning/backwash cycles. T

here are no longitudinal seams, for improved mechanical strength and corrosion resistance. TOPM filters are produced in a range of configurations and micron ratings to perform in a variety of liquid and gas applications.

Filter Features– Benefits

  • Constructed entirely of sintered titanium powder
    • Offers high corrosion resistance
  • Cleanable/Backwashable
    • Allows for re-use
    • Maximum economy
  • High Temperature Sintering
    • No media migration
  • Various gasket/O-Ring materials and configurations
    • Easily retrofits most systems

Graver Technologies Filtration specialists

Germ Africa distribute the renowned Graver Technologies range of filtration media, Ion Exchange Resins and adsorbents.

In the 1880’s Graver was part of Union Tank Carbide, which Supplied water treatment for pressure steam boilers.

Graver then became central to the supply of water treatment equipment to power generation and chemical processing industries.

The Graver Chemical Company which had become a Supplier of Ion Exchange resins, adsorbents and condensate filters was then established.

And finally Graver Technologies came along with a name change in 1998 with expansion into filtration and separation technologies.

The headquarters are now located in Delaware, USA, and Graver Technologies has become one of the world’s largest manufacturers of filtration products.

Graver Technologies quality systems are ISO 9001:2000 compliant, and their membrane filters are flushed, tested and packaged in a Class ISO 7 clean room, they have a suitable filter cartridge for almost any liquid or compressed gas filtration application.

The Graver Range includes a wide variety of filter cartridges in the following formats.

Graver Technologies is one of the fastest growing filtration companies in the world and continues to server its clients with quality products at affordable prices.
