Datasheet summary
AG LE H series
Engineering summary from PDF text extraction for AG LE H series. Verify every value with the OEM datasheet.
Summary
Product identification
The AG LE H Series of thin-film reverse osmosis (RO) elements are designed for brackish water applications, balancing low energy and high rejection requirements. These elements are often used where flux control is needed due to an increased risk of fouling, such as with surface water sources.
All AG LE H Series elements have NSF/ANSI/CAN 61 certification.
Models
- Membrane Type: Thin-film membrane (TFM), polyamide
- Outer Wrap: Fiberglass

General Guidance
- Treat RO elements with care; do not drop the element.
- Each RO element is wet tested, preserved in a 1% weight sodium bisulfite solution, and vacuum packed in oxygen barrier bags.
- During storage: Avoid freezing and direct sunlight. The temperature should be below 35°C (95°F).
- After installation:
- Keep the RO elements wet and use a compatible preservative for storage duration longer than 7 days.
- During the initial start-up, discharge the first permeate to drain for 30 minutes.
- Permeate back pressure should not exceed feed pressure at any time.
- The RO elements shall be maintained in a clean condition, unfouled by particulate matter, precipitates, or biological growth.
- Consider cleaning if the pressure drop increases by 20% or water permeability decreases by 10%. Use only chemicals which are compatible with the membrane.
