Works with Pentair GRO systems and conventional RO systems; requires appropriate drain-line-flow-control for retrofitting
The Pentair GRO-36EN (4004423) is a 36-gallon-per-day encapsulated reverse osmosis (RO) membrane designed for residential and small commercial systems. It offers exceptional water efficiency, achieving up to 100% water savings compared to traditional membranes while maintaining excellent purification performance. Its "dry packed" design maximizes shelf life.Compatible with both Pentair GRO and conventional RO systems, the GRO-36EN requires the appropriate drain-line-flow-control for retrofitting. For installation guidance, refer to the provided retrofit instructions. This innovative membrane employs Thin Layer Composite (TLC) technology, allowing a 1:1 wastewater-to-purified water ratio, significantly reducing waste.
