Frequently Asked Questions: SG30LE PRO-440 — Semiconductor-Grade Low-Energy
What does “semiconductor grade” mean?
SG elements are built to a higher cleanliness standard for ultrapure-water (UPW) trains, with high rejection of small organics (TOC) — critical in semiconductor, electronics, and pharmaceutical water systems.
What are the SG30LE PRO-440's specifications?
11,500 GPD with 99.5% stabilized / 99.0% minimum rejection at 150 psi test pressure (2,000 ppm NaCl, 77 °F, pH 8), 440 ft² (41 m²) active area, 28-mil LDP (low-differential-pressure) feed spacer, 600 psig maximum operating pressure.
How is it different from the previous SG30LE generation?
DuPont rates the PRO generation at up to 5% energy savings and up to 50% lower pressure drop than the previous SG30LE product, thanks to the LDP feed spacer and current precision fabrication platform, while keeping semiconductor-grade cleanliness.
Is it a drop-in 8-inch element?
Yes — standard 8″ × 40″ element (1.125″ permeate tube), fits any standard 8-inch pressure vessel, 600 psig maximum operating pressure. No system modifications required.
