A filter system and clamp system for a gas turbine air inlet uses a single clamp system that allows for securing in place both a first element and a second element on the grid of the gas turbine air inlet. The clamp system can be released to allow for services of the first filter element, while the second filter element remains in sealing engagement with the grid.

Clamp system and filter arrangement and methods

Filtration media packs, filter elements, and media are disclosed, including media packs having a plurality of layers of single facer media wherein the layers of single facer media include a fluted sheet, a facing sheet, and a plurality of flutes extending between the fluted sheet and the facing sheet, with the fluted sheet and facing sheet formed of multi-layer media can include a polytetrafluoroethylene (PTFE) layer supported by a polymeric scrim layer.

High efficiency filter media

Fibrous filter medium that includes a melt-blown filter layer comprising melt-blown fibers and a high-efficiency glass-containing filter layer comprising glass fibers.

Filter media and elements

A filter element is provided according to the present invention. The filter element includes: (a) a media pack arrangement having first and second opposite ends, said media pack arrangement comprising: (i) an inner liner defining a safety central open volume; (ii) a multilayer laminate media construction circumscribing the inner liner and having a first end and a second end, wherein the multilayer laminate media construction comprises: (A) a filtration media layer arranged in a waved configuration, wherein the filtration media layer has a first side and a second side; (B) a first fibrous support layer adjacent the first side of the filtration media layer arranged in the waved configuration; (b) a first end cap at the first end of the media pack arrangement; said first end cap having a central aperture in flow communication with said safety central open volume; and (c) a second end cap at the second end of the media pack arrangement; said second end cap being a closed end cap. An air cleaner is provided, and a media pack is provided.
