20160096133 | FILTER MEDIA SUPPORT CORE - A single support core for a filter media assembly. The single support core includes a single longitudinal tube extending between a first end and a second end. A plurality of orifices are defined in the tube, the orifices align circumferentially along the longitudinal length of the tube. A first plurality of portions defined between the first end and an intermediate annular ring joint and a second plurality of portions defined between the intermediate annular ring joint and the second end. The orifices in each of the first portions and second portions are equidistance circumferentially from each other defining rings. The rings are equidistant longitudinally from each other in each of the portions and the rings are longitudinally spaced differentially in the adjacent portions. The plurality of orifices direct fluid flow through the tube to yield a high flow velocity in predetermined areas along the length of the filter assembly. | 04-07-2016 |
20160023153 | MULTI-STAGE FILTER WITH PRESSURE RELIEF APPARATUS - A filter apparatus, a pressure relief apparatus methods are provided. The filter apparatus includes a tubular hull having an inlet port and an outlet port. A tubesheet partition separates the tubular hull interior into a first stage portion and a second stage portion. A plurality of filter elements are mounted in annular guides. A pressure relief apparatus is configured to relieve pressure through at least one of the annular guides with the pressure relief apparatus in parallel fluid circuit with the filter elements. The pressure relief apparatus includes an elongated tube, a sealing plug, an end cap, a rod disposed within the elongated tube with one end of the rod coupled to the sealing plug and another end of the rod coupled to the end cap; and a spring disposed in the elongated tube between the sealing plug and the end cap. | 01-28-2016 |
20150089909 | MULTI-STAGE FILTER ELEMENT ASSEMBLY - Multi-stage filtration apparatus is provided. A fluid is forced through different filter stage elements allowing for removal of various contaminants from the fluid. | 04-02-2015 |
20140373714 | Filter Elements, Coalescing Baffles, Filtration Vessel and Methods - Improvements to filtration and vessels such as for filtration and coalescing of gas streams are shown. A filter element with a partial treated region and untreated region such as providing different surface energies or other filtration characteristics are provided. Various keying arrangements for compatibility and/or rotational locking are shown between the filtration vessel, a tubular coalescing baffle, and/or filter element. The tubular coalescing baffle also may include non-louvered pore structure, which provides for more even flow in a two stage type filtration vessel to prevent premature exiting and reduction of flow velocities along the second stage, and/or may additionally or alternatively include drainage apertures such as drain slot formed along a gravitational bottom or otherwise to facilitate additional drainage of coalesced liquid as opposed to letting such liquid be forced through fluid velocity toward the open end of the tubular baffle. | 12-25-2014 |
