50 Micron Pleated PP Filter

Balancing solid particle capture with strong flow, the 50 Micron Pleated Polypropylene filter is a versatile mid-range cartridge in Nelsen's commercial Red Series. Its 50-micron rating targets the sediment, silt, and grit that cloud water and clog equipment, while the pleated polypropylene construction sustains the high throughput that commercial systems require, making it a true all-rounder for many treatment trains.

Why 50 Microns?

A 50-micron cartridge sits in the practical sweet spot for many commercial pre-filtration jobs. It is open enough to maintain high flow and resist rapid clogging, yet fine enough to remove the visible particulate that affects water clarity and to protect downstream carbon, softeners, and RO membranes from premature fouling. That balance is why 50-micron filters are so widely chosen as a primary sediment stage where a finer filter would clog too quickly and a coarser one would let too much through.

• 50-micron rating for effective mid-range sediment removal
• Pleated design delivers high dirt-holding capacity
• Cleanable media (5 micron and up) for a reusable service life
• Handles Red Series service flow rates up to 150 gpm
• Low pressure drop, under 15 psi at rated flow
• 100% cellulose-free polypropylene media

Because Red Series cartridges in this range are cleanable rather than strictly disposable, facilities can frequently rinse and reinstall the filter, stretching its useful life and reducing consumable spending over time, a benefit that adds up quickly in high-volume operations. The pleated structure folds a generous amount of media into a standard cartridge body, which means longer intervals between service and steady performance even under demanding loads. As a reliable primary pre-filter or a standalone sediment stage, the Nelsen 50-micron pleated PP cartridge keeps commercial water flowing clean and protects the more sensitive and costly equipment it feeds.

For many commercial sites, a single 50-micron stage strikes the right balance on its own, capturing the bulk of nuisance sediment while sustaining the flow a busy operation requires. Where water is heavier in fines, it works equally well as a second stage behind a coarser cartridge, refining the water before it reaches carbon or membranes. Watch for a climbing pressure drop as the signal to clean or replace, and you will get reliable, repeatable service. Backed by Nelsen's commercial Red Series engineering, this 50-micron pleated PP cartridge is a versatile, dependable choice for everyday sediment control.
