NP20-20, Nelsen Dirt Cart. 20", 20 Mic Spun Poly, SDF-25-2020

Nelsen melt-blown sediment filters feature a graded density that uses the entire depth of the filter to trap sediment, translating into high dirt-holding capacity. Other features include: thermally bonded fibers will not migrate into water, filters available from 1 to 25 microns, broad chemical compatibility. Melt blown polypropylene cartridges offer a self-supporting, thermally fused filter media that requires no separate center support tube. No adhesives, binding agents or anti-static agents are used.
