Abstract: There is described a filter assembly (2) comprising a filter housing (15) and a removable filter cartridge (16) arranged and/or arrangeable within the filter housing (15). The filter assembly (2) comprises an expelling device configured to exert an expelling force onto the filter cartridge (16) when being arranged within the filter housing (15) for at least partially directing the filter cartridge (16) out of the filter housing (15) and a control device controllable into a locking configuration for blocking the filter cartridge (16) within the filter housing (15) and/or for counter-acting against the expelling force and an unlocking configuration for allowing the expelling force to at least partially expel the filter cartridge (16) from the filter housing (15). The control device comprises at least a first interaction element (20) and a second interaction element (21) interacting and/or being configured to interact with one another with the control device being controlled into the locking configuration.

Abstract: A modular particle collection system includes a hollow lower member, a hollow upper member separably attached to the hollow lower member, a collection container separably attached to a longitudinal end of the hollow lower member opposite the hollow upper member, an inlet portion extending radially from the hollow lower member and configured to be fitted to a first portion of a vacuum system, a particulate filter, and an outlet portion extending radially outward from the hollow upper member and configured to be fitted to a second portion of vacuum system. Additional modular particle collection systems and a method of making a modular collection system are also disclosed.

Abstract: A vacuum cleaner filter bag with an inlet opening including a deflection device and an air-permeable material is provided. The deflection device is arranged in the interior of the vacuum cleaner filter bag in the area of the inlet opening and which is implemented such that an air current flowing in through the inlet opening can be deflected by the deflection device. The air-permeable material layer is arranged in the interior of the vacuum cleaner filter bag, is connected to the vacuum cleaner filter bag at least one point, and includes at least one part that is not connected to the vacuum cleaner filter bag and that includes part of the boundary of the material layer.

Abstract: A vacuum cleaner includes a housing having a filter bag cavity. A suction generator and a bag mount are both carried on the housing. Additionally, the vacuum cleaner includes a bag caddy that is displaceable between an operating position connected to the bag mount and a bag disposal position disconnected from the bag mount.

Abstract: The present invention provides a vacuum cleaner comprising a body housing an electric powered blower, a dust case being connected to and free to be detached from the body, a lid having an intake and being fitted to the dust case, which lid is free to be opened and closed, a bag-shaped filter being freely fitted to and removable from the inner surface of the lid and communicating with the intake, and a dust dumping aperture provided in the dust case and accessible by pivoting away a filter housing unit, the dust dumping aperture being used to remove the bag-shaped filter from the dust case.

Abstract: A suction cleaner having a motor fan unit and a casing having a dirt bag receiving compartment closed by a bag carrier in the form of a door and having a bag mount therein in the form of an air conduit extending from the motor fan unit. A dirt collecting bag can be disposed on each of the bag carrier and the bag mount. The bag carrier and the bag mount are relatively movable towards one another to automatically cause a latching assembly to secure a bag on the bag mount, with an opening of the bag in sealing engagement with the air conduit. The bag mount is movable between a bag unloading position away from said casing, and an operative position in which the bag is carried by the bag mount away from the bag carrier.

Abstract: An apparatus which uses suction to draw radioactive particles through a high efficiency filter and contains such filtered particles in a disposable bladder-filter unit for subsequent disposal. The bladder-filter unit prevents the escape of filtered radioactive particles to the ambient atmosphere during the operation of the apparatus and also during disposal, as well as preventing the radioactive contamination of the remainder of the apparatus.
