3M™ 740 Series Filter Cartridges are our large diameter, polypropylene microfibre pleated depth media cartridges for use in filter housings that accept 16.51 cm outside diameter and 101.6 cm length filter cartridges with 226 o-ring connections.
For high efficiency, outside to inside flow direction liquid filtration use 3M™ 740 Series Filter Cartridges. Designed for applications with high contaminant removal requirements our cartridges permit higher flow rates than standard 6.35 cm diameter products resulting in significantly fewer required filter cartridges for a given flow. 3M polypropylene microfibre forms the basis of the filtration media utilised in the 3M 740 Series Filter Cartridges. Our manufacturing processes allow for tightly controlled specifications resulting in a filter media with consistent and predictable particle retention characteristics. The microfibre media is pleated in a radial design (a 3M innovation) which optimises the usable surface area of the filter cartridges. 3M 740 Series Filter Cartridges utilise polypropylene end caps, outer sleeves and cores to protect the pleat structure integrity and provide a robust filter construction. A double o-ring seal design is incorporated to reduce the risk of fluid bypass. 3M 740 Series Filter Cartridges are offered in micron grades ranging from 1μm to 70 μm (at 99.9% particle removal efficiency).
