Abstract: According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

Abstract: A method is provided for supporting environmental control in a semiconductor wafer processing space, the method includes: flowing a first gas under pressure in a first direction through a first diffuser tube, thereby generating a first lateral flow of gas through a sidewall of the first diffuser tube; flowing a second gas under pressure in a second direction through a second diffuser tube, thereby generating a second lateral flow of gas through a sidewall of the second diffuser tube, the second direction being opposite the first direction; combining the first and second lateral flows of gas within a housing; and outputting the combined lateral flows of gas from the housing to produce a laminar gas flow covering an opening to the semiconductor wafer processing space.

Abstract: A filter element for a heating, ventilation, and/or air conditioning (HVAC) system includes a filter media and a support element. The support element includes a first interface member, a second interface member, and a connecting member. The first interface member and the second interface member define opposing lateral ends of the support element and extend parallel to one another. The first interface member and the second interface member are engageable with complementary receiving structures of a rail to support the support element on the rail. The connecting member is coupled to the filter media and extends from the first interface member to the second interface member. The connecting member includes a concave portion extending from the first interface member and a convex portion extending from the second interface member.

Abstract: Air cleaner assemblies, components, features and methods of assembly and use are described. Example air cleaner assemblies are depicted and described in which a main filter cartridge sealing surface is recessed from an open end of a housing body. An access cover of the housing is configured with a portion extending inwardly to engage a main filter cartridge portion and bias it against the main filter cartridge sealing surface. In selected assemblies, the portion of the access cover extending inwardly toward the main filter cartridge, is a precleaner having flow separator tubes therein.

Abstract: A filter for an HVAC system has a body formed entirely of an air-transmissive open-cell polymeric material. The body is of a generally rectangular configuration. The body has a plurality of cuts extending entirely through a thickness of the body from the top to the bottom of the body. The plurality of cuts define a plurality of cubical members frangibly connected together such that each of the plurality of cubical members is separable by hand from a remainder of the body such that an individual cubical member is removable along both a portion of a length and a portion of a width of the body.

Abstract: A vacuum pump that evacuates an inside of a vacuum chamber and powder capturing devices disposed on an intake side of the vacuum pump are included. The powder capturing devices include a plurality of flow path forming units that form a continuous gas flow path from an intake unit located on the vacuum chamber side to an exhaust unit located on the vacuum pump side. The plurality of flow path forming units include a first flow path forming unit having a first catching unit that causes the powder sucked from the intake unit to collide and then catch the powder, and a second flow path forming unit having a second catching unit that causes the powder passing through the first flow path forming unit to collide and then catch the powder.
