2 High Flow Filtration System The High Flow Filtration System is an advanced design that uses 3M Innovation and extensive filtration experience to deliver a high flow filter in a compact housing design. When compared to conventional cartridge systems, this system provides the following advantages: High Flow Capability The unique construction of High Flow Filters (patent pending) permits flow rates of up to 1,893 lpm (5 gpm) in a single cartridge. The result? Fewer filter elements to accommodate your flow requirements. In fact, the High Flow Filtration System requires as few as one-tenth the number of elements as competitive 64mm (2.5 ) pleated cartridges (see Figure 1). Compact Design Using fewer elements combined with an outside-to-in flow path enables a reduction in the size of housing required for your application. The High Flow takes up as little as one-half the size of competitive housings for a given flow rate. The result is lower capital investment costs and a compact footprint that saves valuable plant space (see Figure 1). Ease of Use The High Flow Filtration System is designed with ease-of-use in mind. From a user-friendly, ergonomically designed handle that makes cartridge installation and removal easier without the use of special tools or other hardware, to a unique "twist-to-lock" cartridge seating mechanism that provides a positive seal, the High Flow System facilitates easy operation and maintenance of your filter system. High Performance Media in an Innovative Design High Flow Filters are designed using state-of-the-art technology, optimising both performance and effluent quality to ensure customer satisfaction. The elements use a unique pleat design that results in a high usable filtering surface area per filter. Radial pleat design 3M Innovation is at the heart of the High Flow Filter. A patent pending compound radial pleat design maximises the usable surface area per filter. Blown microfibre forms the basis of the filter media, which is made to tightly controlled fibre diameter specifications to produce a media with absolute rated particle retention characteristics. Our unique manufacturing process embosses the media to produce a more uniform pleat pattern, which, in turn, allows greater utilisation of the media by evenly distributing the fluid throughout the entire filter structure. This results in consistent particle retention in a compact, space-saving design. Compound Radial Pleat design maximises usable media surface area Design Features The High Flow Filter contains several features to combine high performance with easy operation. Ergonomically designed handle facilitates fast and easy insertion and removal without use of special tools. Twist to lock seating mechanism provides positive seal. All Polypropylene construction provides wide range of compatibility with various fluids. Patent pending Compound Radial Pleat maximises usable surface area per cartridge. 75mm (3-inch ) core allows up to 1893 lpm (5 gpm ) through single filter element. P2
