The PP series cartridges consist of 100% pure polypropylene fibers that have been spun together to form a gradient density from outer to inner surfaces. These cartridges, designated as the P-series, have been specifically designed to ensure purity by not affecting the taste, odor, or color of the filtered liquid, within the recommended temperature range. The use of polypropylene also provides superior chemical resistance and prevents bacterial attack. The cartridges’ coreless strength is achieved by sintering the numerous fibers into a durable matrix.
To meet all filtration requirements, PP Series cartridges are available in various sizes and micron gauges.
