GE Osmonics Pentair TFM-50 RO Membrane is a 12" x 2" replacement cartridge providing 50 gallons per day of pure water and can fit RO systems that use standard Thin Film Composite Membranes(TFM/TFC) with capacities between 18 and 150 gallons per day. This GE Osmonics RO membrane reduces lead, mercury, chromium, nitrates and many other pollutants and contaminants. Primarily a residential class RO filter, the TFM-50 membrane can also handle commercial applications in restaurants, vending machines, pharmaceuticals, laboratories and electronics.

Pentair TFM-50 (or new model TLC-50) is manufactured with "Membrane-Separation Technology" which employs cross-flow filtration where captured impurities on the membrane are constantly swept away by the concentrate stream. Cross flow filtration across the membrane then divides the flow into two outflow streams: the cleansed permeate feed and the concentrate or reject stream. This flow provides continuous cleaning that prolongs membrane life and reducing maintenance costs.

Membrane elements by GE are the brand of choice for most demanding applications. GE drinking water filters reduce many pollutants and contaminants with a premium membrane process that removes particles 100,000 smaller than human hair. The elements deliver outstanding performance and long-lasting operation.

Key Features & Benefits:

  • 50 gallons per day capacity.
  • Thin Film Composite Membrane for efficient purification.
  • Cross compatible with other RO filter brands.
  • Extended filter life.
  • ANSI/NSF 58 listed for performance.
