M3 DFT Classic Filter Cartridges

Summary

Product identification

M3 DFT Classic® Series Filter Cartridges are high capacity depth filter cartridges featuring positive double O-ring sealing.

Features

• Double O-ring sealing effectively eliminates potential fluid bypass in most applications.
• No epoxies or glues to contaminate fluid streams.
• Fits most standard 222 O-ring housings.
• Wide range of retention ratings to meet specific application requirements.
• Inexpensive alternative to pleated cartridges.
• Polypropylene or cotton media suitable for a wide range of applications.
• Extends life of expensive final filters in many applications.

Operating limits

• Maximum differential pressure: 3.45 bard @ 25°C (50 psid @ 77°F)
• Maximum operating temperature: 60°C @ 2.8 bard (140°F @ 40 psid)
• Recommended change-out differential pressure: 2.4 bard (35 psid)
  • Provided that the maximum differential pressure is not exceeded based on temperature limits defined above.
