3M is a world leader in the design, manufacture, and marketing of a comprehensive line of filtration products for the separation, clarification, and purification of industrial products.

3M CUNO´s fluid processing provides filtration and separation solutions to a wide range of users in processing and manufacturing industries. Whether it's process water clarification, fine ink pigment classification, or removal of contaminating solids from natural gas, 3M CUNO has the filtration product to meet your needs.

3M CUNO's world-class manufacturing plants are located throughout the world assuring a consistent supply of advanced filtration products.

Three innovative examples of 3M CUNO´s various filtration solutions are:

DUOFLO™ - AN ADVANCED ALTERNATIVE TO STANDARD BAG FILTERS

The patented DuoFLO filter system is an advanced alternative to standard bag filters. This filter media, featuring a true graded-porosity structure, is now available to users of standard bag-type filters and housings. This feature, combined with a 62% increase in filter surface area, ensures that DuoFLO filters provide: 

• Up to four times the service life of conventional felt filter bags 
• Superior contaminant removal efficiency 
• Enhanced flow per filter element 
• Reduced total filtration costs by minimizing production downtime, disposal and labor costs

The DuoFLO design incorporates an innovative new geometry of both filter element and restrainer basket which provides 100% three-dimensional support of the DuoFLO media.  This eliminates the potential for filter element rupture and the resulting gross contamination of the downstream effluent with previously removed particles. In addition, the unique design of the DuoFLO element reduces filter element hold-up fluid volume by 67% compared to conventional bags, minimizing worker exposure to process fluids. 

3M CUNO utilizes state-of-the-art technology to produce the DuoFLO filter element such that both performance and filtrate quality are optimized and customer satisfaction is ensured. DuoFLO filter elements are sized to replace conventional bag filters and are available in both polypropylene and polyester materials with nominal ratings from 1micron to 100micron. 

CTG-KLEAN® - ENCLOSED FILTRATION SYSTEM WITH DISPOSABLE FILTER PACK

CTG-Klean is a totally enclosed filtration system that uses a separate pressure vessel and disposable filter pack to isolate the product to be filtered from the housing. This exclusive design eliminates the extensive time and labour involved with filter change-outs and cleaning of conventional housings.

Environmental concerns and operator exposure to product cleaning solvents are substantially reduced. The streamlined system, coupled with high performance, long-life filters, make CTG-Klean the clear choice for safe, environmentally friend, cost effective filtration.

POLYNET™ ALL-POLYPROPYLENE FILTER

The all-polypropylene filter is constructed using a patent pending process that utilizes flow enhancing filter media and an innovative flow pattern. The result is an absolute-rated filter with vastly superior on-stream life that provides more cost effective filtration than conventional melt-blown filter technologies.

• Superior service life - as much as four times greater dirt holding capacity than competitive filters
• All polypropylene depth filter cartridges for broad chemical and temperature compatibility
• Ratings from 1microcon to 70microns to suite a wide range of applications
• Absolute-rated performance for consistent filtration quality
• Exhibits superior particle retention under increasing differential pressure

3M CUNO helps you achieve process improvements and cost savings in your manufacturing processes through innovative filtration systems.
