• Min. Concentrate Flow Rate: 4 gpm (0.91 m³/hr)
• Element shell material: FRP (Fiber Reinforced Plastic)

Dimensions and Weight

For model RE4040-FLR:

• A: 40.0 inch (1,016 mm)
• B: 3.9 inch (99.0 mm)
• C: 0.75 inch (19.1 mm)
• D/E: 1.05 inch (26.7 mm)

Each membrane element is supplied with one interconnector (coupler) and four O-rings. All RE4040 elements fit nominal 4.0 inch (101.6 mm) I.D. pressure vessels.

General Handling Procedures

• Elements in boxes must be kept dry at room temperature (7–32°C; 40–95°F) and not stored in direct sunlight.
• For WET-TYPE, 1% sodium metabisulfite solution is added as a preservative.
• Permeate from the first hour of operation should be discarded.
• Stabilized salt rejection is generally achieved within 1–48 hours of continuous use.
• Keep elements moist at all times after initial wetting.
• Avoid excessive pressure and flow spikes.
• Only use chemicals compatible with the membrane elements and components.
• Permeate pressure must always be equal to or less than the feed/concentrate pressure to avoid damage.
• The element shell is FRP (Fiber Reinforced Plastic). Awareness of glass fiber strands and safety equipment use is advised.
