FG-Series Pleated Microglass Media

FG-series high purity pleated borosilicate microglass filter cartridges offer high-efficiency retention of particulate matter from liquid and gaseous fluid streams.

FG Series Pleated Depth Cartridges

FG-Series Overview

Favored for its superior retention efficiency, low-pressure drop, and greater contaminant loading capacity relative to alternative media. Suitable for food and potable water contact, the FG-Series delivers to the high-performance demands in food production and bottled water. Also has broad use with process water, lubricants, and a range of fine chemicals. Manufactured in a clean-room environment to maintain high standards of purity and cleanliness. Offered in both absolute-rated (up to 99.98% retention) and nominally-rated (90% retention)
