Filtration media includes a layer of nonwoven fibrous material [10, 110], a layer of sintered porous material [30], and a web of bonding material [20] between the layer of nonwoven fibrous material [10, 110] and the layer of sintered porous material [30]. The nonwoven fibrous material [10, 110] is preferably attached to the web of bonding material [20] to form a first laminate [60, 160], and the sintered porous material [30] is attached to the web of bonding material [20] of the first laminate [60, 160]. The filter media [70, 170] is configured to withstand harsh industrial vacuum filtration environments, resist delamination, and be used on large industrial vacuum filters. A method of manufacturing a filter media is also disclosed. |
