WF-Junior Pleated cartridges are best suited for small-volume filtration. Available filter materials are polypropylene-micro-fiber, hydrophilic PES Membranes or hydrophobic PTFE Membranes. As a speciality WF-Junior cartridges can also be offered made entirely of stainless steel with stainless steel mesh. These are then not pleated, but cylindrically wound around a perforated core. WF-Junior Pleated cartridges feature an external diameter of 56 mm and are available in two different lengths of 76 mm and 138 mm. The internal o-ring is made of viton, silicon or EPDM and functions as a mount and seal on a housing protrusion with a 19 mm diameter.
Due to their overall size, WF-Junior Pleated cartridges must be built into corresponding WF-Junior filter housings. These housings are available made of polypropylene, PVDF or stainless steel.
