150 Micron Pleated PP Filter

Coarse, high-flow sediment control is the job of the 150 Micron Pleated Polypropylene filter, the open-rated workhorse of Nelsen's Red Series. With its wide 150-micron rating, this cartridge captures larger debris like sand, grit, scale flakes, and rust particles while allowing very high service flow, which makes it an ideal first stage ahead of finer downstream filtration in commercial systems.

The Right Job for a Coarse Filter

A pre-filter at this micron level does the heavy lifting so finer cartridges and sensitive equipment don't have to. By knocking out the bulk of coarse particulate up front, the 150-micron cartridge extends the working life of the finer carbon and absolute-rated filters that follow it, protects pumps and RO membranes from abrasive debris, and keeps overall maintenance costs and downtime down. Putting a coarse filter first is simply good system design.

• 150-micron rating for high-flow coarse sediment removal
• Pleated polypropylene maximizes dirt-holding capacity
• Cleanable media for an extended, reusable service life
• Supports Red Series service flow rates up to 150 gpm
• Low pressure drop of less than 15 psi at rated flow
• 100% cellulose-free construction for broad compatibility

Because Red Series pleated cartridges rated 5 micron and up are designed to be cleanable, this 150-micron filter can often simply be rinsed and returned to service rather than discarded, a meaningful economic advantage in commercial settings that see a steady sediment load. The pleated polypropylene construction packs a large amount of media into a standard body, sustaining high throughput with minimal pressure drop even as it loads with debris. For installers building a staged filtration train, the Nelsen 150-micron pleated PP cartridge is the dependable, high-capacity starting point that makes every stage behind it work better and last longer.

For facilities dealing with seasonal sediment spikes, such as well systems after heavy rain or municipal lines after main work, a coarse 150-micron stage absorbs the brunt of those events and shields the rest of the train from sudden overload. Pairing it with progressively finer cartridges downstream creates an efficient, cost-effective filtration sequence in which each stage removes only what the one before it left behind. Cleanable, high-flow, and built to Nelsen's commercial standards, the 150-micron pleated PP cartridge is a smart anchor for any staged sediment-management strategy.
