Pentek S1 Series Filter

Pentek / Ametek / Culligan S1 Series Water Filters

Also branded as: Pentek / Ametek / Culligan / Kleen Plus / Plymouth Products / Pentair / American Plumber / Bruner / US Filter CBC Series

S1 Series cartridges are manufactured from a pleated cellulose media and are designed for general water filtration purposes.

The media is pleated around a polypropylene core for added strength and the ends are immersed in a thermo-setting vinyl plastisol. Embedding and sealing each end of the pleat in this fashion fuses the three components together forming a unitized end cap and gasket.

An external netted sheath helps retain uniform pleat spacing in high flow and pulsating flow streams. The overlap seam is sonically welded to reduce bypass improving filtration efficiency.

S1 Series cartridges are economically priced and highly effective at reducing sediment particles down to 20-microns in size. Pentek / Ametek / Culligan S1 Series Water Filters
