FG

Summary

Product identification

The FG-Series High Purity Pleated Borosilicate Microglass Filter Cartridges offer high-efficiency retention of particulate matter from liquid and gaseous fluid streams. They are favored for their superior retention efficiency, low pressure drop, and greater contaminant loading capacity.

These cartridges are suitable for food and potable water contact, delivering high performance in food production and bottled water. They also have broad use with process water, lubricants, and a range of fine chemicals. Manufacturing occurs in a clean-room environment to maintain high standards of purity and cleanliness.

The FG-Series is offered in both absolute-rated (up to 99.98% retention) and nominally-rated (90% retention) grades in common adapter configurations.

Typical applications include:

• Food & Beverage
• Deionized Water
• Process Water
• Fine Chemicals
• Wastewater
• Produced Water
• Wine Clarification
• Sweeteners

Mechanical / hydraulic
