Pleated Depth Filter Cartridges

Designed for High Dirt Holding Capacity and a Long Service Life  

Pall’s Pleated depth filter cartridges are a state-of-the-art technological advancement – combining traditional and modern forms of filtration. These pleated depth filter cartridges consist of varied fiber diameters, leading to pore-size gradients from upstream to downstream – meaning the pores get finer with each layer while providing high-void volume throughout the depth of the filter medium. 

Designed to remove suspended solids, also known as sediment, turbidity, or particulate - Pall Pleated depth filters are a long-lasting, cost-effective solution with highly compatible polypropylene filter media.
