Mechanical / hydraulic
- All dimensions are shown in Inches (millimeter).
- Element Length: 40 (1,016)
- Element Diameter: 7.9 (201) (also listed as 8” in the product performance table)
- Permeate Tube Diameter: 1.125 (29)
Operating information
- Elements are wet tested, treated with a 1% by weight percent sodium bisulfite storage solution, and then vacuum packed in oxygen barrier bags, or treated with tested feed water solution and vacuum packed with deoxidant inside.
- For short term storage, shipment, or system shutdown, elements should be immersed in a protective solution containing 500 - 1,000 ppm of sodium bisulfite (food grade) dissolved in permeate.
- Permeate from the first hour of operation shall be discarded.
- The customer is fully responsible for the effects of chemicals that are incompatible with the elements. Their use will void the element Limited Warranty.
