GFH-Series High Purity All-Halar Fluoropolymer Depth Media

GFH-Series are ideal for filtration of aggressive solvents, acids, and caustics.

Constructed of 100% ECTFE Halar for superior chemical tolerance in demanding industrial applications. The meltblown microfiber media provides excellent flow at low-pressure drop and greater contaminant holding capacity relative to membrane-based options. The >90% typical retention efficiency allows for use as either a pre-filter or final filtration solution.
