3M Series DF

3M™ Series DF Cartridge Filters

The new name for Cuno DuoFlo.
The 3M™ DF Series filter system, formerly known as CUNO DuoFLO, is an advanced proven alternative to the use of standard bag filters.
Developed using 3M Purification‘s extensive depth filtration experience,
the 3M DF filter features a true graded-porosity media structure and a 62% increase in filter surface area.
Compared to conventional felt filter bags,

Features / Benefits

• Longer service life – up to 4 times or more that of conventional felt filter bags.
• Reduced filter usage - helps minimise product loss, labour, 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 and related disposal costs.
• Used element retains less liquid, making it lighter weight for easier removal.
• Eliminates displacement balloons and associated spillage during change-out.
• Eliminates filter rupture, contaminant bypass and unloading.
• Allows operation to higher differential pressures before filter change-out.
• Maximizes utilisation of filter surface area and maintains low operating pressure drop.
• Reduces flow per unit area (flux) for improved efluent quality.
