3M™ DF Series Filter Systems Datasheet

The 3M™ DF series filter system is an advanced proven alternative to the use of standard bag filters. Developed using 3M Purification Inc.'s extensive depth filtration experience, the 3M DF series filter features a true graded-porosity media structure an 62% increase in the filter surface area. Compared to conventional felt filter bags, 3M DF series filters provide:

• Up to 4 times or more the service life
• Superior contaminant reduction efficiency
• Enhanced flow per filter element
• Reduced losses associated with frequent filter change-outs, (production downtime, disposal, and labor costs)

The 3M DF series filter will easily retrofit most existing bag filter housings. To take advantage of the 3M DF series system in applications where bag filter housings are currently in use, simply remove the existing bag support basket, replace it with a 3M DF series support basket, and insert the 3M DF series filter. For new installations, 3M Purification offers a full line of 3M DF series filter housings.

Features & Benefits
Unique filter design combining a graded-porosity media with 62% greater filter surface area

• Longer Service Life- up to 4 times or more that of conventional felt filter bags
• Reduced Filter Usage- minimizes product loss, labor, disposal costs, and operator exposure
• Increased productivity- less down time for filter change-out

Hold-up volume reduced by 67% compared to conventional bag filters

• Reduced product loss & related disposal costs
• Used element retains less fluid, making it lighter weight for easier removal
• Reduces displacement balloons and associated spillage during change-out

100% downstream support of the filter element

• Reduces filter rupture, contaminant bypass and unloading
• Allows operation to higher differential pressures before filter change-out

Superior flow characteristics

• Maximizes utilization of filter surface area and maintains low operating pressure drop
• Reduces flow per unit area (flux) for improved effluent quality
