The ULP1812-75 Reverse Osmosis Membrane is a high-efficiency, ultra-low-pressure RO element designed to deliver reliable water purification while reducing system operating pressure and energy consumption. Engineered using advanced thin-film composite (TFC) membrane technology, this membrane effectively removes dissolved solids, salts, heavy metals, and other contaminants commonly found in municipal and well water supplies.
With a nominal production rate of 75 gallons per day, the ULP1812-75 is ideally suited for residential reverse osmosis drinking water systems, under-sink filtration units, and point-of-use applications. Its ultra-low-pressure design allows optimal performance even in systems with lower inlet pressure, helping extend pump life and improve overall system efficiency.
The standard 1812 membrane format ensures broad compatibility with most residential RO housings, making replacement quick and straightforward. High salt rejection rates help maintain consistent water quality, while durable membrane construction supports extended service life when used with proper pretreatment.
Whether you are upgrading an existing RO system or replacing a worn membrane, the ULP1812-75 provides dependable filtration performance, improved water taste, and reduced operating costs — making it a trusted choice for residential water purification.
