CUNO High Flow Filtration Systems

1 CUNO high Flow Filtration Systems a 3M company+Innovative technologyto achieve flow rates upto 500 gpm per element+Absolute-rated forconsistent productquality+Operator-friendlycartridg e and housingsystem+Unique design to reducecapital investmentexpensesHigh FlowPerformance in aCompact DesignCUNO high Flow Filtration SystemThe CUNO high Flow Filtration system is an advanced design that uses 3M Innovation and CUNO s extensivefiltration experience to deliver a high flow filter in a compact housing design. When compared to conventionalcartridge Systems , this system provides the following advantages: high Flow CapabilityThe unique construction of CUNO high Flow Filters (patentpending) permits flow rates of up to 500 gpm in a single result? Fewer filter elements to accommodate your flowrequirements. In fact, the CUNO high Flow Filtration Systemrequires as few as one-tenth the number of elements ascompetitive pleated cartridges (see Figure 1).

2 Compact DesignUsing fewer elements combined with an outside-to-in flow pathenables a reduction in the size of housing required for yourapplication. The CUNO high Flow Housing takes up as little asone-half the size of competitive housings for a given flow result is lower capital investment costs and a compactfootprint that saves valuable plant space (see Figure 1).Ease of UseThe CUNO high Flow Filtration system is designedwith ease-of-use in mind. From a user-friendly,ergonomically designed handle that makes cartridgeinstallation and removal easier without the use ofspecial tools or other hardware, to a unique"twist-to-lock" cartridge seating mechanism thatprovides a positive seal, the CUNO high Flow Systemfacilitates easy operation and maintenance of yourfilter + high flow capability of up to500 gpm per cartridge+Reduced Filter Usage minimizes product loss, labor, disposal costs, operator exposure.

4 The elements use a unique pleat design thatresults in a high usable filtering surface area per pleat design3M Innovation is at the heart of the CUNO high Flow Filter. A patentpending compound radial pleat design maximizes the usable surfacearea per filter. Blown microfiber forms the basis of the filter media,which is made to tightly controlled fiber diameter specifications toproduce a media with absolute rated particle retention unique manufacturing process embosses the media to produce amore uniform pleat pattern, which, in turn, allows greater utilization ofthe media by evenly distributing the fluid throughout the entire filterstructure. This results in consistent particle retention in a compact,space-saving FeaturesThe CUNO high Flow Filter contains several features to combine highperformance with easy operation.+A large diametercore allows up to500 gpm through asingle filterelement.
