KleanCap capsule filters is family of full size capsule filters. Polypropylene media absolute rated filter capsules are highly retentive, graded porosity, pleated polypropylene media filters that have been specially designed for clarification and pre-filtration applications. The graded porosity design removes particles in sequence by size – larger particles by the more open outer layers and smaller particles by the tighter inner layers. The outer layers act as a pre-filter while the inner layers provide the absolute rating at the specified pore size. This efficiently spreads the contaminants throughout the media matrix resulting in superior contaminant holding capacity, lifetime, and pressure.
