HC-61 Series

HC-61 SeriesHigh Capacity Wound Filter Cartridges

HC Series-61 polypropylene string wound filter cartridges are certified to comply with materials safety requirements of NSF/ANSI 61 "Drinking water system components - Health effects." These filters are manufactured to be used by water municipalities and in various points-of-entry (POE) potable water systems. In addition, these filters  are made using polypropylene complying with FDA CFR 177,1520. HC high capacity string wound filters, formerly sold under the Delta Pure name, provide excellent filtration for fluids with a wide particle size distribution. The HC series filters are wound with two zones in order to provide longer filter life with challenging fluids. A more open pre-filtration section serves to protect the downstream media and remove large particles, while a tighter final filter section provides removal of smaller particles. The rating to each zone is specified in order to provide a filter uniquely tailored to process requirements. Precision winding geometry provides consistent removal efficiency. Ratings are available from 0.5 um to 200um. Polyester or polypropylene core covers allow added containment removal assurance. Cartridges are available in continuous lengths from 3" to 72" and diameters from 2" to 4.5" End fitting options allow installation into most filter housings.
