Key Features & Design Advantages
How the RO-PLUS Pressure Tank Works
ROT-6 stores supplemental water securely between the butyl rubber diaphragm and the polypropylene liner, while the nitrogen-filled air chamber maintains constant system pressure. When a drinking tap or coffee maker is activated, the compressed nitrogen pushes the purified water into the system at a controlled pressure.
This specialized design ensures stable performance, completely separates the water from the metal shell, and maintains a clean water zone that is completely free of rubber or plastic odors.
