There is provided an air cleaner including: an outlet pipe through which air is discharged; an airflow meter that is inserted toward an interior of the outlet pipe through a wall of the outlet pipe; and a flow-regulating member that is formed projecting from an inner surface of the outlet pipe at a leading end side of the airflow meter, the flow-regulating member including an edge that is formed with a peaked shape with respect to the inner surface and that runs along a direction of flow of air, a rear end that is formed at a downstream end of the edge in the direction of flow, and that is shaped cut sharply toward the inner surface and a width-narrowing portion that decreases in width in a circumferential direction of the outlet pipe on progression downstream in the direction of flow.

The present invention relates to a vacuum pump (1) comprising a casing (2) in which are disposed a first inlet orifice (21) and a second outlet orifice (22) to allow the flowing of a flow of air (F), and in the interior of which a filtering element (3) is mounted in a removable way, wherein at least one orifice of the said casing (2) selected from among the said first inlet orifice (21) and the said second outlet orifice (22) is disposed on an exhaust lid (4) which is at the same time removable from the said casing (2) but integral with the said filtering element (3) and wherein the connection between the casing (2) and the exhaust lid (4) is not tight. The present invention also relates to a cartridge (30) for the corresponding vacuum pump (1) wherein an exhaust lid (4) is integrated in the said closure nozzle (32) of the filtering element (3), the connection between the casing (2) and the exhaust lid (4) not being tight.

A horizontal elongated industrial air filter having an elongated housing. The housing has a filter section with an intake and an exhaust. The housing has filter media in operative communication with the intake. Mounted adjacent the filter media is a blower to pull air into the intake through the filters and push the air out of the exhaust. Reverse pulse pipes extend through the interiors of the filter media to inject air through the filter to remove accumulated particulate. A hopper containment section extends below the filter housing section, and includes a plurality of spaced slots extending through its bottom to receive particulate ejected from said filter media. Connected to the hopper containment section is a vacuum channel to pull particulate in the hopper containment section through the slots. Mounted to the housing is a spark arrestor. The spark arrestor has an outer shell, an inlet and an inner duct with the outer shell spaced from the inner duct to define a tortuous path. The blower draws air with particulates into the inlet and forces it along the tortuous path with the particulates colliding against the shell and inner duct.

Smoke evacuation system for removal of aerosolized chemical compounds and biological fine particles produced during laser treatment of tissue. The rapid smoke evacuation is achieved by coupling a low capacity vacuum pump to a vacuum valve and a vacuum reservoir to create very high flow rate for very short durations. The opening time of the valve could at least partially overlap the laser pulse duration.

A medical electronic apparatus includes: a casing including a lid portion provided with: a first inlet duct; a second inlet duct; and an outlet duct, the lid portion being configured to open the second inlet duct when the first inlet duct is blocked; a detection unit configured to detect an open/close state of the lid portion; and an output unit configured to output information regarding blockage of the first inlet duct based on a detection result of the detection unit.

An air cleaner includes: a generation unit configured to discharge an electric current by being applied with a high voltage, and generate a plurality of types of discharge products; an air-sending device configured to form a flow of air, and spray the plurality of types of discharge products generated from the generation unit to a space; an estimation unit configured to estimate an amount of dust floating in the space by selecting whether an amount of dust floating in the space is a first estimation amount smaller than a predetermined threshold or is a second estimation amount larger than or equal to the predetermined threshold and larger than the first estimation amount; and a control unit configured to control a generation amount of the plurality of types of discharge products to be generated from the generation unit based on the amount of dust estimated by the estimation unit.

A filter module includes: a dust collection filter, which is a tubular filter having a hollow formed therein, the dust collection filter being configured to filter out contaminants from air flowing from outside an outer circumference thereof toward an interior of the hollow; a photocatalytic filter configured to allow air introduced into the hollow and discharged out of the dust collection filter through an opening above the hollow to pass therethrough; a first filter holder configured to fixedly support the photocatalytic filter and an upper end of the dust collection filter so as not to obstruct air flowing from the interior of the hollow to the photocatalytic filter; and a second filter holder configured to fixedly support a lower end of the dust collection filter.

An air conditioner includes a casing having an air outflowing cavity. A side wall of the air outflowing cavity has an air outflowing opening. The air conditioner further includes an air treatment device disposed in the casing and having an air inlet and an air outlet, and a light emission component provided at an outer peripheral side of the air outlet and configured to emit light towards the air outflowing cavity.

The present invention relates to a backing net for a media pack. The backing net comprises a plurality of longitudinal beams and at least one vane and the longitudinal beam has first and second ends and is arranged to be mounted to the media pack in the longitudinal direction. The vane is attached to longitudinal beams and arranged to extend in the lateral direction of the media pack and adapted to direct an air flow passing through the backing net in a preferred direction. The invention further relates to a media pack with a backing net and a V-type filter having a plurality of media packs.

A filter element is provided with a support frame provided with a first end disk section and a second end disk section. A folded filter medium is connected to the support frame and arranged between the first end disk section and the second end disk section of the support frame. The first end disk section or the second end disk section has a face facing away from the filter medium. The support frame is provided with a fluid guiding channel that guides, when a fluid flow passes through the filter medium, the fluid along the face facing away from the filter medium. A filter assembly with such a filter element and a filter receptacle in which the filter element is exchangeably arranged is provided.
