Select the DuPont FilmTec™ BW30 element you run today to find the matching Blue Membrane Z1 cross-reference and side-by-side specs.
Cross-reference for dimensional and performance equivalence under identical standard test conditions (2,000 ppm NaCl, 225 psi, 25°C, 15% recovery). Current FilmTec™ PRO elements rate permeate flow ~4–5% higher; the MB-Z1-4040 matches the discontinued BW30-4040 on flow and rejection with a larger 85 ft² area. Confirm the exact match for your housing in an RFQ.
