Membrane Filters

Citadel™

Pleated PTFE membrane cartridges with PFA structural components to provide excellent chemical and temperature resistance for aggressive chemical applications. Exhibits outstanding particle cleanliness and very low metal extractables.

ZTEC™ P

Double layer polyethersulfone membrane cartridges fully validated for complete bacterial retention at 0.2 micron to yield product sterility by ASTM 838-05 for the most critical healthcare applications.

ZTEC B

Membrane cartridge  filters constructed of hydrophilic, asymmetric polyethersulfone membrane and polypropylene components. ZTEC-B filters have been validated for the removal of microorganisms.

ZTEC E

ZTEC E microelectronics grade cartridges represent Graver’s latest development in ultrapure water  filtration technology. The cartridges exhibit rapid rinse-up to 18 MΏ-cm resistivity and single digit ppb levels of TOC.

ZTEC WB

Utilizes a special polyethersulfone membrane to provide consistent removal of spoilage organisms. The product offers excellent retention efficiency and extended onstream life, making it an ideal filter for the clarification of beer, wine, and bottled water.

ZTEC G

General grade pleated filter element is constructed of absolute rated, hydrophilic, asymmetric polyethersulfone membrane with extended surface area to allow for a high system flow rate.

TefTEC™

Naturally hydrophobic expanded PTFE membrane filters designed for vent and gas applications. With over 8.5 square feet of filtration area, TefTEC filters provide outstanding flow rates. TefTEC filters are 100% flushed and integrity tested in a cleanroom environment.

TefTEC P

Naturally hydrophobic e-PTFE Membrane cartridges validated for complete bacterial retention to yield product sterility in biopharmaceutical final filtration applications. The sterilizing grade PTFE membrane cartridges are well suited for compressed air applications and fermentation feed air and tank vent applications where absolute microbial retention is critical.

TefTEC V

The economical PTFE membrane cartridge filter provides superior hydrophobicity as compared to polypropylene filters commonly used in utility and tank vent applications. TefTEC V has been demonstrated to produce sterile air utilizing a bacterial aerosol challenge.

WaterTEC™

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.
