GCTB

Summary

Product identification

The GCTB-Series are High Performance Grade Meltblown Polypropylene Filter Cartridges.

Key features:

• Precision process control of fiber diameter and layer density tunes the media to achieve targeted retention efficiency and ensure consistent performance.
• All polypropylene construction presents excellent compatibility with a wide range of chemicals.
• Resists contaminant unloading, even at elevated differential pressures.
• All end configurations available (glued or thermally-bonded).
• Easy cartridge incineration and disposal.
• Free of additives, wetting agents, binders and silicone.

Performance Specifications:

• Micron Ratings: 1, 3, 5, 10, 20, 30, 50, 75, 100
• Efficiencies: High Performance Grade = 90%

Food Safety Compliance:

• Materials of construction comply with FDA regulations for food and beverage contact use as detailed in the US Code of Federal Regulations, 21CFR.
• Materials used to produce filter media and hardware are deemed safe for use in contact with foodstuffs in accordance with EU Directives 2002/72/EC, 1935/2004, and/or 10/2011.
• NSF Certification applies for use only with drinking water. Only products bearing the NSF Mark on the product, product packaging, and/or documentation shipped with the product are Certified.
