Cartridge Filters & Housings

Flotrex - Pleated Filtration

The premier range of pleated particulate cartridges is the Flotrex array from Osmonics comprising three types of media, all meeting FDA acceptance - polypropylene, glass-fibre and Halar. Flotrex is an exceptional general purpose filter, meeting the application criteria for chemical processing, electronics, pharmaceutical, medical and beverage markets.

All Flotrex cartridges are statistically tested, integrity testable, lot-coded and contain no adhesives or additives.

Flotrex polypropylene

Combines pleated and depth filtration advantages 82ºC Polypropylene Manufactured using graded sheets of melt-blown layer polypropylene, FPN cartridges optimise the pleats' depth and density, providing high solids loading for long service life (surface areas are up to 34% greater than on the FAP). Ideal for clarification of bulk fluids at high flow rates, saving on capital filter housing costs whilst maintaining a consistent performance. Whilst flow rates are high on the FAP version, the FPN cartridge is up to 30% improved. FPN cartridges are 98% efficient.

Flotrex polypropylene absolute rated

The cleanest cartridge in the pleated range 82°C Polypropylene The advantage of the Flotrex FAP (absolute rated) cartridge over the FPN is that the confusion over exact efficiency of particulate removal is eliminated. FAP are 99.9% efficient and can therefore be easily cross-referenced to all other absolute rated cartridges. Again, being of all-polypropylene construction, the FAP is of high purity and is the recommended pre-filter to Osmonics' membranes.

flotrex glass-fibre

The highest flow absolute rated cartridge 82°C Glass-fibre An exceptional filter where the filtrate is compatible with glass-fibre. Flow versus pressure drops is far superior to polypropylene cartridges yet the FGF is still absolute rated at 0.45, 1 and 3 micron. Being constructed from 100% FDA acceptable materials with a polypropylene pre-layer on all micron ratings to extend cartridge life, the FGF at 1 micron is ideal for Cryptosporidia and Giardia cyst removal in bottled water (NSF53 cyst reduction certified). Other applications where the FGF is recommended include beverage clarification due to no leaching of flavour altering substances.

flotrex halar

Ozone tolerant for 9000 PPM/HR with no extractables 82°C Fluoropolymer Halar® (ECTFE) is an industrial grade fluoropolymer capable of withstanding the harshest process conditions. The FHR cartridge features 100% Halar construction and is an economic alternative to PFA and PTFE filters whilst maintaining high flow rates and high-purity results with absolute efficiencies at 3, 10 and 25 micron and cut-off characteristics that out-perform the industry's best polypropylene filters. Ideal for ozone and oxidising chemicals.
