GFH

Summary

Product identification

GFH-Series High Purity All-Halar Fluoropolymer Depth Media Filter Cartridges are designed for filtration of aggressive solvents, acids, and caustics. They are constructed of 100% ECTFE Halar for superior chemical tolerance. The meltblown microfiber media provides excellent flow at low pressure drop and greater contaminant holding capacity relative to membrane-based options.

Typical Applications

• Toluene
• Xylene
• Ozonated Process Systems or Water
• Bulk Chemical Polishing

Operating limits

• Change Out ΔP (recommended): 35 PSID
• Temperature (max): 190˚F (88˚C)
• Differential Pressure (max): 60 PSID (4.1 bar) at 68˚F (20˚C)

Product water

The cartridges offer >90% typical retention efficiency, suitable for use as either a pre-filter or final filtration solution.
