Pentair GRO-75EN Encapsulated RO Membrane 75 GPD (No Flow Control)

Pentair GRO-75EN Encapsulated RO Membrane 75 GPD (No Flow Control)

The genuine Pentair GRO-75EN encapsulated TLC (Thin Layer Composite) membrane delivers high-rejection water purification performance for residential under-sink reverse osmosis systems. Engineered with advanced high-recovery technology, the GRO-75 features an exceptional 1:1 waste-water ratio, cutting waste-water down the drain by up to 75% compared to standard, conventional RO membranes.

This specific configuration does not include a built-in drain line flow control (DLFC). It is the perfect direct-fit replacement for systems utilizing an existing external drain line flow restrictor.

Its fully encapsulated seamless plastic design protects against contamination while ensuring high structural integrity. Shipped as a dry-packed element, this membrane offers a long shelf life so it remains at peak filtration readiness until the moment it is installed.

Product Specifications & Performance:

  • Production Rate: Outputs a nominal 75 Gallons Per Day (GPD) of purified water.

  • High Contaminant Rejection: Features a stable 96% TDS rejection rate, heavily reducing dissolved solids, heavy metals, fluoride, and chemical impurities.

  • Plumbing Connections: Equipped with integrated 1/4-inch Quick-Connect fittings for fast, leak-proof installations.

  • Valves Included: Features a built-in permeate check valve to maintain consistent system pressure and prevent backflow.

  • Service Lifespan: Rated for 24 to 36 months of continuous use depending on incoming water hardness and pre-filter maintenance.
