JPW series string wound filter cartridge
An NSF certified string wound filter
String wound filter cartridge consists of multi-hole frames wound closely with textile fibers. Diverse kinds of filtering precision can be realized by controlling the winding density. As the outer bore diameter is larger than the inner one, the filter cartridges have a good deep-level filtering capability. JP series has straight multi-holes from the surface to the inner core, allowing maximum dirt-holding capacity and lowest pressure drop. The holes are now with slope design (25micron -200micron).Read moreAK series carbon block filter cartridge
