Replacement RO Membrane for Excalibur Premium Series RO SystemsThe RO Membrane 100 GPD (RO TFC100) is a genuine Filmtec thin-film composite replacement membrane for Excalibur Premi um Series RO systems. Rated at 100 gallons per day, it's the highest-capacity membrane in the Excalibur lineup — restoring full purification performance for systems with a booster pump and high-output demand.What the RO Membrane DoesThe RO membrane is the most critical component of your reverse osmosis system. It forces water through microscopic pores, blocking dissolved contaminants including lead, arsenic, nitrates, fluoride, chlorine byproducts, and total dissolved solids (TDS) — removing up to 99% of contaminants. Over time, the membrane loses efficiency and must be replaced to maintain water quality and flow rate.Specifications Model: RO TFC100 Type: Thin-Film Composite (TFC) Filmtec Capacity: 100 GPD (gallons per day) Size: 2" x 10" Compatible System: Excalibur Premium Series RO (6-Stage with booster pump) When to ReplaceReplace your RO membrane every 2–3 years, or sooner if you notice a significant increase in TDS readings, reduced water flow, or a change in taste. A TDS meter is the best way to monitor when replacement is due.InstallationInstalls into the 2" x 10" membrane housing of your Excalibur Premium Series RO system.
