A surgical gas delivery device includes a filter cartridge interface and a computer controlled control unit configured to control the circulation of surgical gas during endoscopic surgery. The control unit can operate in a plurality of different modes of operation. A tube set for connecting the surgical gas delivery device to one or more end effectors includes a filter cartridge in fluid communication with the tube set. The filter cartridge is seated in the filter cartridge interface of the surgical gas delivery device to communicate surgical gas between the surgical gas delivery device and the one or more end effectors. The surgical gas delivery device includes a reader operatively connected to receive input from a data carrying element of the tube set. The data carrying element, reader, and control unit can launch a specific one of the modes of operation when the filter cartridge is inserted.

A dirt collector that includes a housing and an air-permeable filter media extending from the housing such that the filter media and housing at least partially define a collection volume. The housing has an inlet opening in fluid communication with the volume and at least a portion of the housing is transmissive of infrared radiation

A vacuum cleaner that includes a suction source configured to generate a suction airflow, a dirt collector in fluid communication with the suction source and configured to separate debris from the suction airflow and the dirt collector is configured to store the debris separated from the suction airflow. The vacuum further includes an infrared sensor operable to output a signal corresponding to a distance to an amount of debris stored in the dirt collector, a controller that receives the signal, and the controller is operable to determine a fill level stored in the dirt collector based on the signal. A visual display displays the fill level stored in the dirt collector.

A filter leakage monitoring device of a particle separator includes a plurality of sampling pipes each of which has a visible part through which an inside of the sampling pipe can be visually recognized, a suction port of each of which corresponds to each of a plurality of filters disposed in a particle-containing air chamber into which air containing particles are introduced, the suction port of each of which is positioned near an air intake port that sucks air that has passed through each of the filters into a clean air chamber, and a vacuum pump that sucks air through each of the sampling pipes.

A filter element comprises a filter media and a restriction indicator device. The restriction indicator device comprises an attachment portion and a movable portion. The attachment portion is attachable to a portion of the filter assembly. The movable portion is movable relative to the attachment portion between a non-buckled position and a buckled position. The movable portion moves from the non-buckled position to the buckled position once a predetermined pressure drop between an upstream side and a downstream side of the movable portion of the restriction indicator device is met.

A powder container including a filter that separates air and powder from each other, a hopper that includes a first opening portion installed below the filter, a second opening portion that has an opening area that is smaller than that of the first opening portion, and an inclined surface that partially overlaps the filter in plan view, a container box installed so as to be detachable from the hopper, the container box containing the powder, and a detection sensor (an optical sensor) installed outside the container box so as to oppose a side surface of the container box, the detection sensor being installed near the second opening portion and near a side of the inclined surface in a lower direction. In the powder container, the optical sensor includes a light emitting element that emits light in a direction extending along the side of the inclined surface in the lower direction so that the light transmits through an area in the side surface of the container box, and a light receiving element that receives the light emitted from the light emitting element.

An air purifier includes: a housing; a fan in the housing; an outlet in a top face of the housing, air being blown out via the outlet; an air passage spatially connecting the fan to the outlet; and an illumination unit configured to illuminate the air passage, wherein the air passage includes an upstream, first air passage and a downstream, second air passage, the first air passage extends upwards, the second air passage has a curved surface or an inclined surface inclined with respect to the first air passage, and the illumination unit illuminates the curved surface or the inclined surface.

A vacuum cleaner that includes a suction source configured to generate a suction airflow, a dirt collector in fluid communication with the suction source and configured to separate debris from the suction airflow and the dirt collector is configured to store the debris separated from the suction airflow. The vacuum further includes an infrared sensor operable to output a signal corresponding to a distance to an amount of debris stored in the dirt collector, a controller that receives the signal, and the controller is operable to determine a fill level stored in the dirt collector based on the signal. A visual display displays the fill level stored in the dirt collector.

The current disclosure concerns a filtering apparatus (10) for filtering the air from an absorbent articles manufacturing process line, said filtering apparatus (10) comprising a. a housing (36) comprising one or more inlets (12); b. a filtering media 14 arranged downstream with respect to the airflow of the one or more air inlets (12); c. a support structure (16) comprising a cylindrical drum (18) comprising a first and second longitudinal ends (49,60), the filtering media (14) being secured to said cylindrical drum (18); d. a motor device (52) to rotate the cylindrical drum (18); and e. a first pump (38).
