20080314009 | FIBER COLLECTING MEDIA STRIP FOR A MIST ELIMINATOR - A fiber bed mist eliminator has a fiber bed which is formed of a composite fiber bed collecting media strip including a collection layer which is not subjected to needle punching. The fiber bed can be made very thin while retaining high efficiency in removing small particles of aerosol from a gas stream passing through the fiber bed. The fiber bed collecting media strip lends itself to be applied to the mist eliminator by spirally wrapping the element onto the mist eliminator. The fiber bed collecting media strip can overlap itself to seal at the locations where the fiber element overlaps itself. The fiber bed collecting media strip can be provided to the field in different formats for use in making a mist eliminator fiber bed. | 12-25-2008 |
20090211214 | Filter plate for a particle filter - The invention relates to a filter plate for a particulate filter which serves to separate particulates out of an exhaust gas flow of an internal combustion engine. | 08-27-2009 |
20100101199 | LAYER FOR USE IN A HEPA FILTER ELEMENT - A layer for use in a HEPA filter element solves the problem of disclosing a filter element which satisfies HEPA requirements. Said layer comprises a first support layer ( | 04-29-2010 |
20130019578 | HIGH EFFICIENCY PAINT ARRESTANCE FILTER - Various examples of the inventive subject matter include a method and corresponding system for fabricating a combination paint arrestance filter for use in the painting industry. Embodiments of the system include a single-stage combination filter having a number of first layer media pockets and a number of second layer media pockets arranged downstream of the first layer pockets. An opening of each of the first layer media pockets is arranged in parallel with one another to receive an incoming airflow into the single-stage combination filter. Each of the second layer media pockets is at least 99.97% efficient at removing 0.3 micron and larger particles at a face velocity on the filter of about 37 meters per minute. | 01-24-2013 |
20140007550 | FILTER DEVICE FOR GAS FLOW LOADED WITH AEROSOLES AND/OR GASEOUS IODINE - The invention relates to a filter device for filtering a gas flow that is loaded with aerosols and/or gaseous radioactive iodine including a housing that is closed fluid tight, including at least one raw gas inlet, a clean gas outlet, at least one filter element including a filter medium, the filter element is arranged in the housing so that a gas flow to be filtered moves from the at least one raw gas inlet to the clean gas outlet only through the filter element, at least one tubular element penetrating the housing from a first pass-through cross-section to a second pass through cross-section which is arranged in vertical direction above the first pass through cross-section, so that an entire inner cavity of the tubular element is exclusively in contact with an ambient fluid surrounding the filter device. | 01-09-2014 |
20140245707 | Filter Part for Fluid Lines - A filter part for fluid lines, preferably high-pressure lines with pressures in the range of 150 to 900 bar, preferably in the range of 200 to 350 bar, more preferably in the range of 700 to 875 bar, for use especially in filling nipples, non-return valves, pressure regulators, cylinder valves, filling couplings, switching valves, break-off safety devices, quick couplings and also as a separate filter part. The filter part comprises a base body and at least one fluid passage opening, wherein the base body and the fluid passage opening are covered by at least one filter element. The invention further relates to a method for producing a filter part with a base body and a filter element, especially in form of a screen filter which is also known as a filter mesh. | 09-04-2014 |
