## Description

Sampson Platinum polyester felt filter bags provide reliable, high-capacity liquid filtration for industrial applications where chemical resistance and thermal stability are critical. Constructed from premium polyester felt media with welded sides and bottom seams, these filter bags deliver consistent particle removal across a wide range of process conditions.
