| 055476000 | WITH MEANS INTRODUCING GAS INTO MIDST OF SEPARATING MEDIA | 8 |
| 20100005766 | FILTERING DEVICE - The invention relates to a filtering device, comprising a tubular filter element and a carrier part, with the filter element fastened thereon. The carrier part can be inserted between an unfiltered fluid pipe and a filtered fluid pipe. The pipes can be assembled into a continuous flow pipe, wherein the filter element protrudes into the pipe interior. | 01-14-2010 |
| 20100050580 | APPARATUS FOR FILTERING GASES AND METHOD OF MANUFACTURING SAME - A filter element may be provided. The filter element may include a fitting; and a filtering member coupled to the fitting, the filtering member may include a plurality of flutes defined in an outer surface of the filtering member. | 03-04-2010 |
| 20100180561 | Filtration Structures For Improved Particulate Filter Performance - A particulate filter may comprise an inlet end, an outlet end, and a plurality of channels disposed and configured to flow fluid from the inlet end to the outlet end, wherein the channels are defined by porous walls configured to trap particulate matter. The porous walls may have a total porosity greater than about 45%, a median pore size ranging from about 13 micrometers to about 20 micrometers, and a pore size distribution such that pores less than 10 micrometers contribute less than about 10% porosity. | 07-22-2010 |
| 20120131892 | DETACHABLE AIR FILTER MACHINE - A detachable air filter machine includes a base, at least one lower filter seat, a machine frame, at least one upper filter seat, an upper lid and two pressure cylinders which are stacked in sequence from bottom to top. The base includes a pair of limit members at two opposing sides thereof. The pair of limit members each is pivotally connected with a buckling member. The upper lid has a buckling portion corresponding to the buckling member for engagement of the buckling member. The user can pull the buckling member to take off the upper and lower filter seats for cleaning. The detachable air filter machine is simple in structure and can be assembled and disassembled quickly for maintenance to save time and effort. | 05-31-2012 |
| 20120186206 | EXHAUST GAS PURIFYING FILTER - There is provided an exhaust gas purifying filter, which includes an inflow surface into which exhaust gas including particulate matter flows, an exhaust surface from which purified gas is exhausted, and a filter substrate which is constructed of a porous body. The filter substrate includes a porous partition and a gas passage which is enclosed by the porous partition, a porous film which includes silicon carbide is provided on a surface of the porous partition. An average pore diameter of the porous film is more than 0.5 μm and 3 μm or less. | 07-26-2012 |
| 20120240537 | OIL SEPARATOR - A disclosed oil separator provided in a flow path of a refrigerant gas flowing from a compressor to a refrigerator including a filter configured to form an internal space by including a filter material filtering out oil from the refrigerant gas, an upper lid bonded to an upper portion of the filter material, and a lower lid bonded to a lower portion of the filter material; a body accommodating the filter; a gas inlet pipe introducing the refrigerant gas into the internal space; and a gas outlet pipe ejecting the refrigerant gas from which the oil is filtered out by the filter from an upper portion of the body, wherein a lower end of the gas inlet pipe is opened to the internal space at a position higher than the lower lid and lower than a substantial center between the upper lid and the lower lid. | 09-27-2012 |
| 20130074461 | Air filter spin flow inlet/outlet housing - An air filtration unit for conveying bulk granular material from a tank trailer, and uses air pressure to achieve granular flow, the air filtration unit incorporates an intake that induces a spiral flow, the unit incorporates a lid at the back end of the filter housing, and a baffle structure at the intake inlet of the unit, to dampen sound. | 03-28-2013 |
| 20140260136 | FILTER ELEMENT - A filter element of a filter device for filtering a fluid may include a ring-shaped filter body from a filter material. The filter body may enclose an interior space in the circumferential direction. A main port may be fluidically connected to the interior space and an auxiliary port may also be fluidically connected to the interior space. The filter body may include a duct that extends axially and is radially open. The auxiliary port may be arranged in a region of the duct. | 09-18-2014 |
