Three pieces of string wound filter cartridges.

Depth Pleated Filter Cartridges – Maximize Filter Cartridge Lifespan

Pleated filter cartridges are designed for advanced and efficient particulate removal performance and high contaminant holding capacity. The pleated media construction provides more than double the surface area of traditional string wound, melt blown and other depth filter cartridges. They are available in PP, PES, hydrophilic PTFE, hydrophobic PTFE and nylon materials. All these have different microfiltration membranes with different performance, which can satisfy most of your fluid filtration requirements.
