Z Tec E Polyethersulphone Membrane Cartridge FIlters
Image 1

Z Tec Electronics grade, fully validated for microbial removal and fully integrity testable using the latest Polyethersulphone membrane technology. This filter has one of the highest effective surface areas of membrane for any comparable product giving long life and low resistance to flow.  Available in ratings from 0.03 micron to 0.65 micron this filter is at the top of the "specification tree" and not to be confused with similar low area untested products from competitors.  Every filter is flushed with 18 megohm/cm water until the system achieves 18 meg ohm / cm resistivity before drying in a clean room and packing. Every filter is integrity tested. This flushing process ensures the fasted "rinse up" time available.  Produced under the cleanest conditions in qualified clean rooms this filter can cut costs and improve performance in ultra pure water applications as well as critical chemical filtration applications.  This filter will not hydrolise unlike Nylon membranes from competitors. We also recommend silicon seals are not used in semiconductor applications as silicon and semiconductors do not go well together.  EPR is the standard seal.  You would be amazed how many UK ultra pure water treatment systems have silicon seals in semiconductor plants, a definite "no no" for those with experience.  If you want high quality filtration in electronics or semiconductor applications the Z Tec E must be a leading contender.

Full comparisons available between this and any competitors product on request.

This filter should be integrity testable in situ with any existing test equipment if required.

QCR Cryptosporidium Parvum Cyst Reduction Filter
Image 1

The QCR filter cartridge is designed and validated for the removal of Cryptosporidium Parvum.  "Crypto." is a recent parasite, not being a bacteria or a virus and very resistant to inactivation by normal water treatment such as chlorination.  Only filtration can guarantee the removal of the threat.  Crypto can kill the elderly, young and those with deficient immune systems.

This filter exceeds all specifications set by NSF 53 and is fully tested as recommended for this application.  Care should be taken when comparing this fully tested and validated product to other products claimed to be 1 micron absolute but not tested and validated and not built to exacting test and quality control standards.

This filter from Graver is ideal for any company producing food or drink products where water is washed onto the finished product or left uncooked.  Many major supermarkets insist that products on their shelves are washed with water filtered to at least this standard

QXL Polypropylene Filter Series
Image 1

QXL is a pleated polypropylene filter which is absolute rated at the stated rating but incorporates the benefits of depth filters and pleated filters.  Spun depth filters offer excellent removal properties for Gels etc but short life, but the QXL offers all the benefits of both types.  The QXL can also be used as an excellent pre filter in water applications due to its graded pre filtration meaning multi stage pre filtration can be repalced with one QXL filter.

QXL is ideal for general water prefiltration, removing in many cases multi stage systems and replacing it with one or two (if membrane final filter required).  It is also ideal for CMP slurry filtration in semiconductor manufacture, Ink Jet Ink filtration and general coatings filtration.

Built to outperform competitors products a full comparison is available if required between the QXL and any other competitors product. 

PMA Polypropylene Filter Series
Image 1

PMA is a pleated polypropylene filter cartridge which is absolute rated at Beta 5000 (99.98% efficiency) from installation.  With ratings from 0.2 to 25 micron this filter is ideal for a wide range of applications.  Manufactured from high surface area media which is 100% FDA approved and produced under strict environmental conditions, this filter is widely used in applications from hospitals and pharmaceutical manufacture to water and chemical production.  This filter outperforms the majority of competitors and where even longer life is required the QMA is available

This filter can be offered in continuous lengths up to 40 inches meaning no welds every 10 inches, no additional seams and fewer joints.

This is the most sold filter by Graver in the UK andthe "workhorse" of many applications.
