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 DuPonts 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
