Element Dimensions and Feed Rates

Various models are available with differing body lengths, element outer diameters, permeate tube inner and outer diameters, tube extension lengths, and feed rates. See the official PDF for exact tabulated values for all dimensions, element weights, and specific feed rates for each model. As an example, model 1812TM has a Body Length of 10.00” (254 mm), Element OD of 1.8” (46 mm), and a Feed Rate of 2.0 GPM (7.6 lpm).

Membrane Area (Sq. Ft.)

Membrane area varies significantly depending on the model and the feed spacer thickness. For a 31 mils feed spacer, example areas include:

• 1812TM: 2.7 sq. ft.
• 2540M: 22 sq. ft.
• 2540F: 23 sq. ft.
• 4040M: 67 sq. ft.
• 4040F: 69 sq. ft.
• 8040F: 317 sq. ft.

See the official PDF for the full table of membrane area values across different feed spacer (24, 31, 46, 65, 80 mils) and element models.

Recommended Element Cross Flow Rate

The recommended cross flow rate is subject to differential pressure limitations and specific applications, and varies with element diameter and feed spacer thickness.

• 1.8” Elements: 3-5 gpm (1 m³/hr)
• 2.5” Elements: 6-9 gpm (1-2 m³/hr)
• 4.0” Elements: 15-24 gpm (3-5 m³/hr)
• 8” Elements: 66-105 gpm (15-24 m³/hr)

See the official PDF for the full tabulated values across all feed spacer options.
