Residential RO Elements
Compact RO membranes for household purification systems.
The OV-ULP 1812 and 2012 families are compact spiral-wound elements for household drinking water purifiers, laboratory systems and other small equipment. They are engineered for low operating pressure and reliable rejection with feed-water TDS below 500 mg/L.
Product Advantages
Designed around the application.
- Low-pressure operation
- Compact element dimensions
- High salt rejection
- Private-label and specification customization
Typical Applications
- Under-sink RO purifiers
- Countertop water systems
- Laboratory pure-water units
- OEM drinking-water appliances
Typical Properties
Model performance data.
Values are based on the defined test conditions below. Actual system performance depends on feed-water quality, pressure, temperature, recovery and pretreatment.
