TefTEC cartridge filters are constructed with naturally hydrophobic PTFE membrane and polypropylene support layers and components. The HIMA retentive PTFE membrane offers superior hydrophobicity and water intrusion resistance compared to PVDF and polypropylene membranes, and the cartridge construction offers a cost-effective alternative to all fluorocarbon filters. TefTEC filters are ideal for gas/vent applications and the filtration of aggressive chemicals and solvents.
TefTEC Filter Features–Benefits

100% Flushed with DI water and integrity tested
Meets applicable CFR criteria and USP Class VI Biological Test for Plastics
Filters are manufactured in an ISO Class 7 Cleanroom Environment
Filters are flushed, tested and packaged in a Class ISO 7 clean room
Manufactured using current Good Manufacturing Practices
Each filter element stamped with pore size, lot and serial number for identification and traceability
Aggressive chemicals • Tank Vents • Strong acids/bases • Compressed gases • Solvents • Photoresists • Pharmaceutical Intermediates • Hot DI water • Fermentation air
The WaterTEC filter series is constructed of absolute rated, hydrophilic, asymmetric polyethersulfone membrane and polypropylene components. The filter is designed for overall filtration economy and provides excellent flow rates and throughputs.
Filter Features– Benefits
Low pressure drop reduces energy costs
High dirt holding capacity minimizes change-outs and down time
All thermal bonded construction with no adhesives
Available in all common configurations to allow use of existing filter housings
Cost effective absolute filtration
All materials are FDA listed for food and beverage contact (U.S. CFR, Title 21)
Pleated Polyethersulfone (PES) Membrane for Critical Filtration in Wine and Beer
ZTEC WB cartridge filters utilize a special polyethersulfone membrane to provide consistent removal of spoilage organisms and inorganic particulate. The product offers excellent retention efficiency and extended on-stream life making it an ideal filter for the clarification of beer and wine.
The PES membrane, available with either 0.65 or 0.45 μm pore sizes, is designed to meet and surpass the filtration criteria necessary to maintain product quality and characteristics. Produced in an ISO Class 7 cleanroom, the cartridges are integrity tested during production to assure performance and consistency.
Filter Features– Benefits
Manufactured in an ISO Class 7 Cleanroom Environment
100% flushed with 18MΩ water and integrity tested Low adsorption of protein, color and flavor components
All materials are FDA listed for food and beverage contact
Repeatably Steamable/Sanitizable High log reduction values for spoilage organisms
High retention (LVR>7) of yeast and other spoilage organisms
Pore size, lot and serial number are stamped on each filter element for identification and traceability

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.
