Zefluor Elements with Gore Tube Filters

Summary

Product identification

Zefluor Elements with GORE ePTFE tube filters are mounted in a CPVC head assembly. They feature a bottom-load CPVC head assembly design for tubular back-pulse Zefluor filters.

Key characteristics:

• 16.5 mm (0.65 in) diameter GORE ePTFE tube filters mounted in head assembly
• Outside-to-in flow traps the contaminant outside of the element
• EPDM porous hose used for internal tube support
• Typical tube length is 1905 mm (75.0 in)

Features

• Increased filtration area – about 2.5x the filtration area for a given volume compared to the filter sock design (Zylon™)
• Use of smaller, less expensive vessels
• Fewer number of elements needed in existing vessels
• Smaller housing diameter
• Ease of installation – new filter tube consists of single piece filter media and support element, allowing quick change-outs and minimal downtime
• More durable – the Zefluor membrane is a thicker and more robust material than a membrane laminate

Operating limits

• Continuous Operating Temperature: 75 °C (167 °F)
• Retention Efficiency: >99 % @ 0.5 micron (typical) per ASTM F 795 test
• Acid/Alkali Resistance: Yes
• Free Chlorine Resistance: Up to maximum 30 ppm permanent

Note: These specifications are valid in fully compatible fluids which do not chemically attack, soften, swell, or adversely affect any of the components of construction.

Feed water

Applications include:

• Chlor-Alkali market: Brine filtration for removal of Ca, Mg, Al, Fe, and Hg precipitates in the primary treatment prior to electrolysis
• Other liquid filtration processes

Mechanical / hydraulic

Materials of Construction:

• Tubing: GORE expanded PolyTetraFluoroEthylene (ePTFE) membrane
• Support material: Ethylene-Propylene Diene Monomer (EPDM)
• Head assembly: Chlorinated Polyvinyl Chloride (CPVC)
• Head assembly screws: Titanium

Dimensions (nominal):

• Membrane tube inner diameter: 16.5 mm (0.65 in)
• Membrane thickness: 0.55 mm (0.02 in)
• Typical tube length: 1905 mm (75.0 in)
• Maximum allowable tube sheet thickness: 90 mm (3.54")
• Other dimensions: 95.3 mm (3.75"), 74.9 mm (2.95"), 2083.7 mm (82.04")
