FilmTec™ LC LE PRO-4040 Reverse Osmosis Elements

Key Features

  • Innovative Low-Pressure Performance: The FilmTec™ LC LE PRO-4040 delivers high-quality water even in harsh conditions, thanks to DuPont’s proprietary low-energy technology.
  • Maximized Active Area: With an industry-leading active area of 94 square feet, this element reduces fouling by operating at a lower flux while achieving higher flow rates.
  • Superior Salt Rejection: Offers high salt rejection at low pressure, making it ideal for challenging water conditions.
  • Effective Cleaning and Durability: The element is designed for robust performance with the widest cleaning pH range (1-13) and excellent chemical tolerance, ensuring long-lasting durability.

Key Applications

  • Ideal for light industrial applications requiring high-quality permeate water.
  • Perfect for harsh feed water conditions.
  • Suitable for drinking water systems, including refilling stations, bottling plants, hotels, schools, and other institutions.

Typical Properties

  • Permeate Flow Rate: 2600 gpd (9.8 m³/d)
  • Minimum Salt Rejection: 99.0%
  • Stabilized Salt Rejection: 99.5%

Test Conditions: The permeate flow and salt rejection are based on 2000 ppm NaCl, 77°F (25°C), 15% recovery, pH 8, and an applied pressure of 150 psig. Individual element performance may vary by ±20%. Specifications may be updated periodically for improvement purposes.
