Assemblies, features, and techniques for pulse jet air cleaner assemblies and their operation are described. Techniques described include methodology and equipment for preferred pulse jet sequencing and operation.

Various embodiments provide for a filter assembly. The filter assembly includes a filter housing, a filter element, and a cover. The cover includes a first cover end and a second cover end disposed axially away from the first cover end. A second coupling member is adjacent to the second cover end. The second coupling member is configured to engage a first coupling member to couple the cover and the filter housing. A biasing member is coupled to the first cover end. An interface plate is configured to press against a first endplate of the filter element to secure the engagement of a first engagement portion of a filter seal member of the filter element and a second engagement portion of a housing seal member of the filter housing.

Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a first alignment portion disposed on the first housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element comprises filter media and a second alignment portion disposed on the first filter end. The second alignment portion is complementary to the first alignment portion. The installation of the filter element within the housing causes the first alignment surface and the second alignment surface to align to provide for engagement of a radial seal between the filter element and the housing.

An air cleaner assembly is disclosed, along with related methods. In one aspect, the air cleaner assembly has a housing including a housing body and a removable cover that together define an interior volume for holding a filter cartridge. The housing can include a first part of a first connection arrangement. The air filter cartridge can include a second part of the first connection arrangement. In one aspect, the first and second parts can be secured together place the air filter cartridge in a latched position by moving the air filter cartridge in a first direction. In one aspect, the first and second parts can be disconnected from each other to place the air filter cartridge in an unlatched position by moving the air filter cartridge in the first direction. The air cleaner assembly can include a second connection arrangement securing the air filter cartridge to the housing cover such that the housing body and housing cover are secured together.

Air cleaner assemblies, components therefor, and features thereof are described. Also described are methods of assembly and use. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. Methods of assembly and use are described.

A filter assembly and method include a body having first second surfaces defining a cavity between the surfaces. A conduit system is disposed within the cavity. The conduit system includes an inlet disposed at the first surface and receives a fluid mixture comprising a fluid and debris. The conduit system is shaped to separate a first portion of the fluid and a mixture of a second portion of the fluid and the debris. The conduit system includes a first outlet disposed at a position within the cavity and a second outlet disposed at the second surface of the body. The conduit system directs the mixture of the second portion of the fluid and the debris out of the conduit system and into the cavity of the body via the first outlet, and directs the first portion of the fluid out of the conduit system via the second outlet.

A dust filtering and collection system for filtering dust and other particles from an incoming air stream generally used for conveying granular material, the filtering system receives the air from within the tank trailer, pre-separates the heavy dust particles and other debris at the bottom of a filter housing, without its impingement upon the filter tube(s) contained upwardly therein, and then passes the partially filtered air upwardly through filter tube(s) for purifying the air before discharge to atmosphere. The filter housing for the system includes a cylindrical housing upwardly, an integral cone shaped housing at its bottom, into which the dust particles settle, it has a transverse plate at its upper segment, which supports the filter tube(s), an air inlet being centrifugally and integrally formed at the bottom of the cylindrical member of the filtration system.

This disclosure provides collector elements for gas circuits of additive manufacturing systems for making 3D components from a powder. The collector elements include an intake duct portion having a strip-shaped inflow duct with an intake opening and a main body portion that includes a cylindrical cavity extending along the intake duct portion, the cavity being fluidly connected to the inflow duct with a step in the rounded wall that causes an increase in diameter from a first diameter of the cavity to a second, larger diameter. The collector element also includes a first gas discharging portion with a tube portion and a diameter adjusting portion that fluidly connects a first end of the cavity to the inner volume of the tube portion via a duct.

An air management assembly for a work machine, the air management assembly having a cooling orifice defined in a panel, a cooling fan generating a cooling airflow through the cooling orifice to a cooling package, at least one fixed screen positioned along an intake orifice, and a first baffle positioned at least partially between the cooling orifice and the intake orifice. Wherein, the first baffle directs the cooling airflow partially across the fixed screen to clear the fixed screen of debris.
