BOS MAX Filter Bags

Summary

Product identification

The BOS MAX Filter Bags are seamless, absolute-rated, heavy-duty filter bags with an advanced design. They feature a semi-rigid microfiber insert that provides extended life, increased efficiency, and greater depth filtration compared to conventional filter bags, while maintaining the absolute filtration capabilities of standard BOS bags.

Features:

• BOS MAX Heavy Duty Extended Life Bags contain a semi-rigid, microfiber cartridge insert, offering up to four times the life of standard BOS bags.
• Ideal for high-purity applications.
• Absolute rated from 3-100 microns for high efficiency and consistent quality.
• Thermally-bonded microfibers contain no sizing, bonding adhesive, resin, or silicone.
• Contaminant-free to eliminate craters, providing better surface results.
• PolyLoc® ring creates a hermetic seal within a vessel housing to prevent liquid bypass.

Available Material:

• Polypropylene
