PureT - RS9 -Compatible Rainsoft, Sears, and Kenmore TFC Reverse Osmosis Membrane 50 GPD
50 GPD TFC Reverse Osmosis Membrane for Rainsoft, Sears, and Kenmore Systems
This PureT thin-film composite membrane is engineered as a direct replacement for the RS9 cartridge used in Rainsoft, Sears, and Kenmore reverse osmosis systems. The 50 gallon-per-day rated membrane fits standard 10-inch housings and removes dissolved solids, heavy metals, and contaminants down to 0.0001 microns through semi-permeable TFC film technology.
Thin-Film Composite Separation
Feed Water Enters
Pre-filtered water enters the membrane housing under system pressure, typically 40-80 PSI, forcing molecules against the TFC barrier layer.
Selective Filtration
The thin-film composite layer allows only pure water molecules to pass through while rejecting dissolved solids, salts, heavy metals, nitrates, and organic compounds at 0.0001 micron level.
Permeate and Reject
Purified water exits to the storage tank at approximately 50 gallons per day while concentrated waste water flushes contaminants to drain, maintaining membrane surface integrity.
Replace every 24-36 monthsSystem Requirements
This membrane is designed for Rainsoft reverse osmosis systems using the RS9 membrane cartridge, as well as compatible Sears and Kenmore models with 10-inch membrane housings. The 1.8-inch diameter fits standard residential TFC membrane housings. Verify your existing membrane dimensions before ordering. Best performance requires sediment and carbon pre-filtration, minimum 40 PSI feed pressure, and water temperatures between 40-100°F. Total dissolved solids rejection rate typically exceeds 95 percent with proper system maintenance.
