High purity pleated borosilicate microglass filter media offers 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 media delivers high performance demands in food production and bottled water. Also has broad use with process water, lubricants, and a range of fine chemicals. Offered in both absolute-rated (up to 99.98% retention) and nominally-rated (90% retention) grades in common adapter configurations.
