Summary

Product Identification

The Eaton LOFMEM-W Series is a disposable, absolute-rated membrane filter cartridge designed for economic overall filtration. It utilizes polyethersulfone and polypropylene components that are both hydrophilic and asymmetric.

Key Features:

• High dirt-holding capacity for long service life.
• Economic absolute filtration.
• FDA listed (U.S. CFR, Title 21) materials of construction for food and beverage contact.
• Available in multiple configurations.
• All-thermal bonded construction; no adhesives.
• Validated for USP, Class VI standards for plastics.

Recommended Applications:

• General water filtration
• DI water prefilter/postfilter
• Aqueous-based chemical processing

Operating Limits

• Sustained maximum operating temperature: 180°F (82°C) at 20 psid (1.38 bar)
• Maximum differential pressure:
  • 60 psid @ 80°F (4.14 bar @ 27°C)
  • 30 psid @ 160°F (2.07 bar @ 71°C)
  • 15 psid @ 200°F (1.03 bar @ 93.3°C)
• Recommended change-out pressure: 35 psid (2.4 bar)
