ULP-4021 Ultra Low Pressure RO Membrane

In stock

The ULP-4021 is an ultra-low pressure RO membrane element, specifically developed for the treatment of surface water, groundwater, and tap water with a salinity of up to 2,000 mg/L. Thanks to the combination of high salt rejection and low required operating pressure, this membrane is particularly suitable for compact and energy-efficient systems.

The membrane is widely used in smaller installations such as water vending machines, drinking water systems in buildings, and laboratory applications. Due to its compact size and stable performance, the ULP-4021 is a reliable choice for situations where space and efficiency play an important role.

  • Compact membrane for small RO systems
  • High salt rejection up to 99.2%
  • Suitable for water up to 2,000 mg/L
  • Ideal for vending machines and drinking water systems
  • Low energy consumption due to low operating pressure
