CN04 and CN04CF

CN04 and CN04CFDual Media String Wound and Carbon Cartridges

CN04 and CN04CF Series cartridges are dual media string wound and carbon cartridges which provide removal of chlorine, chemical contamination and sediment, and also improve the taste and odor of water.

The CN04 utilizes an inner carbon-impregnated cellulose media with an outer string wound wrap of polypropylene or cotton media to extend the life and enhance the performance of the carbon.

The CN04CF (Cellulose-free) version utilizes an inner coconut shell carbon-impregnated polyester media with an outer string wound wrap of polypropylene or cotton media. The CN04CF is an excellent choice for chemical processing applications such as plating solutions.
