A 4040 membrane refers to a type of reverse osmosis (RO) membrane element, like the ProTool RO Membrane 4040 Ultra Low Pressure, which measures approximately 4 inches in diameter and 40 inches in length. This 4040 reverse osmosis membrane is designed for ultra-low pressure operation, making it highly efficient in commercial and industrial water purification systems. It fits easily into standard 4040 RO membrane housing and is ideal for systems needing moderate flow rates and compact design.
