Summary
Product identification
The MICRODYN RO LE series consists of Low Energy Brackish Water Reverse Osmosis (RO) Elements designed for water purification applications requiring reduced energy consumption. These elements feature a low energy membrane for upgrading RO systems and operate under low pressure conditions. They are certified to NSF/ANSI Standard 61 for use in drinking water systems.
MICRODYN RO elements are available in standard 4-inch and 8-inch spiral-wound designs.
- Membrane Chemistry: Thin-Film Composite Polyamide
- Construction: Spiral-Wound Membrane Element with Fiberglass Outerwrap (some models use Tape Outerwrap)
- Stabilized Salt Rejection: 99.3%
- Minimum Salt Rejection: 98.8%
All models on this sheet have diamond shaped feed spacers.
Element Specifications
Test conditions for permeate flow: 1,500 ppm NaCl, 10.3 bar (150 psi), 25°C (77°F), 15% recovery, pH 8.0, 30 minutes operation. Flow rates will be no more than 15% below the values shown.

Mechanical / Hydraulic
The physical dimensions for the elements are as follows:
| Model | Dim. A – mm (inches) | Dim. B – mm (inches) | Dim. C – mm (inches) | Permeate Tube | Outerwrap Type | Element Weight – kg (lb) |
|---|---|---|---|---|---|---|
| 4040-LE | 1,016 (40.0) | 99 (3.9) | 19.1 (0.75) | Male | Tape | 4 (9) |
| 8040-LE-400 | 1,016 (40.0) | 201 (7.9) | 28.6 (1.125) | Female | Fiberglass | 16 (36) |
| 8040-LE-400/34 | 1,016 (40.0) | 201 (7.9) | 28.6 (1.125) | Female | Fiberglass | 16 (36) |
| 8040-LE-440 | 1,016 (40.0) | 201 (7.9) | 28.6 (1.125) | Female | Fiberglass | 17 (37) |
- For Female elements, Dimension “C” is the Inner Diameter. For Male elements, “C” is the Outer Diameter.
- Male elements have a protruding permeate tube. Dimension “D” (not in table, but referenced in diagram description) is 26.7 mm (1.05 in).
- Element shipping weight depends on packaging material and quantity.

Important Information
- Start-up: It is recommended to flush elements for 30 minutes at low pressure and discard permeate during the flush prior to operation.
- Cleaning: MICRODYN RO membrane elements must be cleaned periodically to ensure proper operation.
- Storage: Elements must be stored appropriately to ensure proper operation.
- Regulatory: All models on this sheet are certified to NSF/ANSI Standard 61 for use in drinking water systems.
