Description
4 x 40 Inch Ultra Low Pressure RO Element – 2000 Gallons Per Day
The ULP (Ultra-Low Pressure) series is an excellent choice for high-quality water
production. It is widely used in new installations and system upgrades, particularly
when cost-effectiveness and productivity are key considerations. Excellence in automated manufacturing ensures that all membrane elements maintain consistent performance.
The ULP series membrane elements are manufactured without pre-chlorination,
ensuring high water output and salt rejection efficiency. This design also enables chemical cleaning across the widest pH tolerance range (1-13).
NSF/ANSI Standard 61 Certified
Base RO elements are manufactured using NSF/ANSI 61 certified materials by an accredited OEM.
Additionally, these membranes are manufactured without pre-chlorination, enabling chemical cleaning across a wide pH tolerance range (pH 1–13) and delivering consistent long-term rejection performance.
