Varafine VFSG Filter Cartridges

Summary

Product identification

The VARAFINE™ VFSG Series Filter Cartridges are high flow asymmetric membrane filter cartridges.

Key features:

• Absolute Rated at >99.9% Efficiency with retention ratings of 0.05, 0.1, 0.2, 0.45, 0.65, 0.8, or 1.2 µm.
• Patented Highly Asymmetric Membrane ensures superior flow rates and long life.
• Contaminants trapped and held by positive mechanical retention.
• Manufactured in an ISO Class 7 Cleanroom.
• Pre-flushed and tested with ultrapure 18 Megohm-cm water.
• Compatible with most sanitizing agents.

Operating limits

• Filter Grades (>99.9% Retention Rating by Standard Latex Bead Challenge): 0.05, 0.1, 0.2, 0.45, 0.65, 0.8, 1.2 µm
• Maximum Differential Pressure:
  • 20 psid (1.4 bard) @ 203°F (95°C)
  • 80 psid (5.5 bard) @ 68°F (20°C)
• Recommended Change Out Differential Pressure: 35 psid (2.4 bard) (provided that the maximum differential pressure is not exceeded based on temperature limits)
• Chemical Compatibility: Cartridge resists most acids and bases, pH 1-14, and most oxidizing agents.
• Sanitizing Agents: Cartridge may be sanitized in place with common oxidizing agents.

Product water

• Rinse-Up: Cartridges will rinse-up to 18 Megohm-cm in less than 6 minutes at a flow rate of 2.6 gpm (10 lpm).
