FILMTEC™ Membranes
Fiberglass Elements for Commercial Systems

Fiberglass Elements

• Permeate flow and salt rejection based on the following test conditions: 2,000 ppm NaCl, applied pressure as above, 77°F (25°C) and 15% recovery.
• Permeate flows for individual elements may vary +/-20%.
• For the purpose of improvement, specifications may be updated periodically.
• LE-4040 replaces BW30LE-4040.
