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.

Favored for its superior retention efficiency, low pressure drop, and greater contaminant loading capacity relative to alternative medias. 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)

FG-Series Performance Chart

*All data is based on absolute rated medias. Nominally rated medias will result in a pressure drop reduction of approximately 10%.
