Our exhaust bag filters, also known as cube or extractor filters, are used primarily for final overspray capture in the industrial and aerospace industries. The standard efficiency filter is constructed of a single layer of one-ounce nonwoven polyester, while the higher efficiency filter adds a second layer of our E.P. media for total overspray capture. Exhaust bag filters come in a standard 15” single pocket model, as well as dual-pocket model for when expanded surface area is needed. Exhaust bag filters come in standard sizes of 20”x20”, 20”x25”, and 24”x24”.
