FilmTec™ LC LE PRO-4040
Key Features:
• LC LE PRO-4040 delivers high quality water at low pressure at harsh water conditions, using DuPont’s
Innovative, proprietary technology for low energy applications.
• Industry leading active area (94 sqft) which provides less fouling due to lower operating flux while still
Achieving higher flow.
• Offers high salt rejection at low pressure in harsh water conditions.
• Provides most effective cleaning performance, robustness and durability due to it’s widest cleaning pH
Range (1-3) and chemical tolerance.
Key Application:
• Light industrial applications requiring good permeate quality.
• Harsh feed water condition.
• Drinking water-Refilling stations, Bottling plants. Hotels, Schools, Institutions etc.
