Pentek (161079) 4-Stage RO-2550 Reverse Osmosis System 50 GPD
The Pentek RO-2550 50 GPD delivers exceptional water purity for residential point-of-use applications
Four-stage filtration with GE/Desal 50 GPD thin film composite membrane removes contaminants down to 1/1000 of a micron. NSF-certified for salt and dissolved mineral reduction.
Four-stage process for comprehensive contaminant reduction
Pre-filter removes particulate matter, sediment, and suspended solids to protect downstream components
High-capacity carbon block reduces chlorine taste and odor while providing enhanced dirt-holding capacity
GE/Desal 50 GPD thin film composite membrane filters particles as small as 1/1000 of a micron, reducing salts and dissolved minerals
Final carbon stage polishes water before dispensing, ensuring optimal taste and clarity at the faucet
Proven technology for residential drinking water
Comprehensive Reduction
NSF-certified to reduce salts, dissolved minerals, bad taste and odor. Effective on both chlorinated and non-chlorinated water supplies.
50 Gallons Daily
GE/Desal thin film composite membrane produces up to 50 gallons per day, sufficient for household drinking and cooking needs.
Automated Efficiency
Automatic shut-off valve stops production when the 2.8-gallon bladder tank reaches capacity, reducing water waste.
Compact Installation
Module measures 13.5" × 16.5" × 5.25" with separate 9.5" × 14" tank. Designed specifically for under-sink point-of-use placement.
Complete Package
Includes all cartridges, long-reach chrome air-gap faucet, and installation hardware. Ready for residential installation.
Technical details for the Pentek RO-2550
Replacement schedule for optimal performance
Sediment Pre-Filter
Replace sediment cartridge based on water quality and household usage. Higher sediment loads require more frequent replacement.
Carbon Block Filter
Replace carbon block cartridge to maintain chlorine reduction and taste/odor control. Chlorinated supplies may require more frequent changes.
RO Membrane
Replace GE/Desal thin film composite membrane when flow rate decreases or TDS levels increase. Lifespan depends on source water quality.
Post Carbon Filter
Replace final polishing cartridge annually to ensure optimal taste and odor control at the point of dispensing.
