Test conditions & reference basis

Dimensions: All A / B / C / D1 / D2 values are in mm. A: element length; B: element diameter; C: element tube diameter; D1: element end diameter; D2: element end spacing (source terminology).
Flow basis: Average permeate flow in GPD, not industrial GPD (m³/d). Pressure and recovery are model-specific.
Source variability: Individual element flow may vary by 15%; rejection may vary by 2%, as stated in the source.

Specify with confidence.

Confirm the exact model, current data-sheet revision, feed-water limits and test conditions before finalizing your design. The published specifications follow the designated source for this series; no legacy-only model variants are combined into this table.
