Abstract: A filter device has a filter housing (10) receiving a first filter element (12), through which a medium may flow in a given direction, and has a bypass device (22). Along with the first filter element (12), a second filter element (32) is provided. The filter elements are arranged in series, one behind the other, in the direction of flow. When the bypass device (22) is activated, the second filter element (32), immediately following in the direction of flow, filters the medium. The second filter element thus takes over the main filtration of the medium on actuation and operation of the bypass device, since the first filter element is essentially no longer available for a filtration process due to the bypass device.

Abstract: An air filter and corresponding filter element for use in an internal combustion engine are disclosed. The filter element has a seal bead made of an elastomeric material that forms the frame of the filter element. A pleat block, made of a filter media, is molded into the seal bead in a first area of the filter element and a baffle is located in a second area of the filter element to protect the pleat block from wetting. A channel is formed in one side of the seal bead which allows the filter element to be retained during assembly without the use of fasteners and a surface is formed opposite the seal bead that in conjunction with the channel seals the filter element within the air filter when the air filter is fully assembled. The air filter has an intake silencing chamber that is located to receive outside air before it is provided to the pleat block and a sealed flow path is created from the intake silencing chamber to the pleat block by a third area of the filter element.

Abstract: A filter is provided which combines a woven wire mesh over a supporting body. The supporting body is typically a metal perforated tube which provides fluid communication between the well bore and the production equipment string. The woven wire mesh acts as a filter to prevent the influx of sand particles, provides openings oriented at various angles relative to its surface, so that some area is available for fluid entry even when particulate matter is lodged on the surface above an opening, provides interior channels that allow fluid to travel from one location on the mesh surface to another location over an opening into the supporting body, and does not provide "straight-through" openings, thus forcing the fluid to make multiple turns to pass through the mesh, thereby dissipating the fluid's energy and increases the mesh's erosion resistance. When particulate matter accumulates on the mesh's surface, the resulting particle cake remains porous, heightening the filter's resistance to plugging.

Abstract: An apparatus especially suitable for filtering out a particulate material from a carrier fluid such as flue gases is disclosed herein. This assembly utilizes a main vessel defining an interior compartment and having an inlet and separate outlet. A number of filter assemblies are disposed within the vessel compartment and supported therein in spaced relationship with one another and with the vessel itself by means of a single tubular member which also serves as a discharge pipe between the filter assemblies and the vessel's outlet.

Abstract: A gas cleaning installation, such as might be used to filter particulate material from exhaust gases of a power generating boiler or the like, which comprises a pair of gas cleaning chambers each containing filtration means for a gas stream passing through the installation. The chambers are spaced apart to define between them a gas inlet passage or passages into the underside of each chamber and, above, the inlet passage or passages a gas outlet passage or passages. The gas outlet passage or passages together include a portion extending at least part way across the upper end of each chamber, the outlet passage or passages communicating with each chamber through an aperture extending between the interior of the chamber and the interior of the respective portions of the gas outlet passage or passages.

Abstract: A reverse pulse baghouse equipped with a self-contained service chamber having ventilation control in which ambient cooling is induced by the exhaust fan of the baghouse. Within the dirty-air plenum, the bags are of progressively greater length toward the center of the baghouse in order to minimize particle reentrainment and each bag is sealed against an integral collar of the tube sheet to prevent gas leakage. The hopper section, for funneling dust cake to a hinged, screw conveyor trough, is removably connected to the upper section of the baghouse and is so sized to invertably nest within the upper section during shipment.
