1 Micron Absolute Pleated PP

For commercial operations that can't compromise on particle removal, the 1 Micron Absolute Pleated Polypropylene cartridge delivers precise, consistent filtration backed by Enpress engineering. As a flagship member of the Red Series, this large-format 8" x 40" cartridge is purpose-built for high-flow systems that demand both fine filtration and minimal pressure loss, the combination that keeps demanding facilities running smoothly.

Absolute-Rated Precision

An absolute micron rating means this cartridge is held to a strict efficiency standard, capturing fine particulate reliably rather than offering a nominal average that lets occasional larger particles slip through. That consistency makes it ideally suited to pre-filtration ahead of reverse osmosis membranes, to sensitive process water, and to any application where downstream equipment depends on genuinely clean feed water. When membrane protection or product-water purity is on the line, absolute filtration earns its keep.

• 1 micron absolute rating for dependable, repeatable fine-particle capture
• Large 8" diameter by 40" length format for high-capacity service
• Pleated polypropylene maximizes surface area and flow
• 100% cellulose-free media for broad chemical compatibility
• Low pressure drop of less than 15 psi at rated flow
• Engineered for commercial Red Series housings

The pleated polypropylene construction folds an enormous amount of media into a compact footprint, which translates directly to longer service intervals and the high dirt-holding capacity that commercial sites need to minimize downtime. With Red Series cartridges supporting service flow rates up to 150 gpm across the lineup, the 1 Micron Absolute option is the clear choice when fine filtration is the priority rather than coarse, high-throughput screening. Installed as a polishing or membrane-protection stage, it shields costly downstream components and keeps commercial water clean and clear. Trust this Enpress cartridge to protect your equipment investment while delivering the consistent fine filtration your process requires.

For facility teams planning a maintenance schedule, the cartridge's large 40-inch length and pleated surface area mean it loads gradually rather than blinding quickly, giving predictable service life and ample warning through rising pressure drop before a change is needed. That predictability is valuable in commercial settings where unplanned downtime carries a real cost. Whether you are protecting a bank of RO membranes, polishing process water, or simply keeping a high-flow line clean, the 1 Micron Absolute pleated cartridge brings absolute-rated assurance to operations that cannot afford inconsistent results.
