The micron ratings shown at various efficiency and beta ratio value levels were determined hrough laboratory testing, and can be used as a guide for selecting cartridges and estimating their performance.

Under actual field conditions, results may vary somewhat from the values shown due to the variability of filtration parameters. Testing was conducted using the single-pass test method, water at 3 gpm/10” cartridge.

Contaminants included latex beads, coarse and fine test dust. Removal efficiencies were determined using dual laser source particle counters.

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.
