A point of use air wand with a built in filtration system may include a wand including a filter body; a filter housed within the filter body; an input endcap attached to a first end of the filter body, the input endcap operatively attached to an air source; and an accumulator endcap attached to a second end of the filter body. Forced air may enter the wand through the input endcap, flow through the filter, and then out of the wand through the accumulator endcap.

A fluid filter has a filter housing with inlet opening for fluid to be cleaned and outlet opening for cleaned fluid. A filter element arranged in an element receptacle of the filter housing separates inlet opening from outlet opening. The filter housing has a housing body with an installation opening to the element receptacle, through which the filter element in an installation direction is introduced into the element receptacle. The filter housing has a housing cover for closing the installation opening. The installation opening is arranged in a transverse side of the housing body that is lateral relative to the housing axis. The filter housing has a sealing surface, surrounding the housing axis at least partially circumferentially, for contacting a seal of the filter element. The filter element has a seal support device for the seal and the filter housing has a pressing device for the seal support device.

The invention refers to a filter arrangement for filtering dust-laden air (7) generated by a hand-guided power tool (1), in particular a sander or a grinder, during operation of the power tool (1). The filter arrangement comprises a filter cartridge (13) having a hollow casing (14), a filter element (22) located inside the casing (14), an air inlet port (15) located downstream in respect to an airflow (8) through the filter cartridge (13) and in respect to the filter element (22) and adapted to be pneumatically connected to the power tool (1) in order to allow the dust-laden air (7) generated by the power tool (1) to flow into the casing (14), and an air outlet port (20) located upstream in respect to the airflow (8) through the filter cartridge (13) and in respect to the filter element (22), the air outlet port (20) adapted to allow filtered air (9) leave the filter cartridge (13). It is suggested that the filter arrangement comprises an active airflow generating device (30) with a fan (40) comprising a plurality of blades (44) and driven by an electric motor (38) separate from an electric motor of the power tool (1), the airflow generating device (30) being in pneumatic connection with the air inlet port (15) of the filter cartridge (13) or with the air outlet port (20) of the filter cartridge (13) in order to generate or support the airflow (8) through the filter cartridge (13).

A filter system and clamp system for a gas turbine air inlet uses a single clamp system that allows for securing in place both a first element and a second element on the grid of the gas turbine air inlet. The clamp system can be released to allow for services of the first filter element, while the second filter element remains in sealing engagement with the grid.

A dishwasher includes a filter member having a handle integrally provided at an upper cover of the filter member. The filter member is accommodated in a filter accommodation space of a filter housing, where a movement space of the filter member is larger than the filter member, thereby preventing damage to the filter material or a fall of contaminants into the filter housing effectively, during withdrawal and insertion of the filter member. A separation space defined between the filter housing and the upper cover of the filter member is closed by a gasket, in the state where the filter member is disposed in the filter housing completely, thereby preventing the flow of non-filtered air into the filter housing effectively.

A dust collector apparatus includes a housing, an airflow generation module and a filter. The housing has one side formed at least one intake vent-hole and another side formed of at least one exhaust vent-hole. An inner side of the housing has an airflow channel formed between the intake vent-hole and the exhaust vent-hole. The airflow generation module comprises an airflow drawing unit for drawing an airflow in order to form the airflow channel between the intake vent-hole and the exhaust vent-hole, a control module for controlling the airflow drawing unit, and a power module. The filter is detachably arranged at the intake end and used for filtering dust in the air sucked by the airflow drawing unit. The dust collector apparatus of the present invention allows the dust particles to be properly collected by the filter without secondary scattering, and guides the airflow to be exhausted smoothly.

A filter support for a filter is adjustable to modify the size and/or shape of the filter. The filter support may include one or more wedges engaging a wall of the filter, and a connector connecting the one or more wedges to one another. The connector allows selective adjustment of the filter support.

An air filtration apparatus includes an airflow powerhead assembly including a fan assembly and a vane assembly, a filter assembly, and a separator chamber housing inside of which the filter assembly is disposed. The separator chamber housing has a chamber inlet at a first axial side and a clean air outlet at a second axial side of the separator chamber housing opposite the first axial side. The filter assembly has a first axial end adjacent the chamber inlet and a second axial end adjacent the clean air outlet. The separator chamber housing includes at least one debris ejection slot extension configured to eject debris from an inner space of the separator chamber housing. The filter assembly includes a debris catch tray disposed at the second axial end, the debris catch tray having a debris ejection slot aligned with the at least one debris ejection slot extension.

An air cleaner system including a housing having a first housing end with an opening, a second housing end, and an inlet proximate the second housing end. The air cleaner system also includes a filter element removably installed within the housing through the opening, the filter element including filter media, a first endplate coupled to the filter media at a first filter end, an open second endplate coupled to the filter media at a second filter end, and an annular projection extending axially from the open second endplate, the annular projection sealing against the housing and creating an axial gap between the filter element and the housing.

An attachable air filter medium for attachment to a conventional circulation fan is disclosed comprising a netting fabric filter medium being adapted to fit over the rear half of the conventional circulation fan's housing for filtering dust particles in air coming into the circulation fan preventing dust buildup on the fan blade thus eliminate the need to periodically clean the fan.
