An motorcycle air intake structure includes: a container divided by a main baffle into two distinct chambers: a first chamber communicating externally and a second chamber communicating with a throttled body via a feeding duct; the two chambers separated by an air filter, positioned at the main baffle, the first and second chambers extending longitudinally side-by-side defining opposite sides of the air intake structure. The air intake further includes a pre-chamber accessing the first chamber, separated therefrom by a cross wall and communicating therewith via an access duct crossing said wall, with an inlet end thereof arranged in the pre-chamber and an outlet end thereof arranged in the first chamber, the pre-chamber arranged on the front side with respect to a forward vehicle direction. The pre-chamber includes a front access mouth; and a diverting baffle interposed between the access mouth and the inlet end of the access duct.

A filtering assembly that receives an inlet air includes a modulation panel subassembly, an air filter subassembly downstream of the modulation panel subassembly, wherein the air filter subassembly is configured to discharge the inlet air from the filtering assembly, and an arm subassembly configured to move the modulation panel subassembly and to move the air filter subassembly. The air filter subassembly moves into and out of a flow of the inlet air.

A system for detecting and cleaning indoor air pollution includes one or more outdoor gas detection devices, a plurality of indoor gas detection devices, a control central processor, and a plurality of filtering devices including one or more directing filtering devices. A directional blower is disposed on the directing filtering device and can be moved upwardly and downwardly, as well as rotating with respect to the directing filtering device. The indoor gas detection device is disposed on the directing filtering device, receiving the control command to enable the directing filtering device and to control the directional blower to be directed toward the air pollution location so as to generate a directed air convection. Therefore, the circulative filtration and the rapid clean of the air pollution can be achieved by the filtering component, allowing the indoor air pollution data to be a safety detection value.

A substrate processing device includes: a chamber; a substrate processing mechanism that has a holding member, and discharges a processing fluid onto a substrate held by the holding member; a joint pipe that has a lower opening provided below the holding member, and an upper opening provided above the holding member, and is disposed such that at least part of the joint pipe from the lower opening to the upper opening passes through the outside of the chamber; and an air flow generator that is provided in the joint pipe. The air flow generator circulates an atmosphere in the chamber by discharging the atmosphere in the chamber from the lower opening to the joint pipe to allow the atmosphere to pass through the joint pipe, thereby introducing the atmosphere again into the chamber via the upper opening so that a downflow of the atmosphere occurs in the chamber.

The invention relates to an extractor fan apparatus for extracting cooking vapours downwards. The extractor fan apparatus comprises at least one fan for aspirating the cooking vapours, an inflow opening for the entry of the cooking vapours into the extractor fan apparatus, a filter seat which is arranged downstream of the at least one fan and on which at least one filter for filtering the cooking vapours can be arranged, and a filter replacement space which extends between the inflow opening and the at least one filter seat, the filter replacement space being configured for the reversible removal of the at least one filter from the filter seat through the inflow opening.

A refrigerator including a cabinet, a liner defining a compartment within the cabinet, a fan to move cooled air, and an air tower positioned adjacent the liner and provided in fluid communication with the compartment via a plurality of primary exhaust openings. The refrigerator further includes an air filter bracket separate from and located adjacent to the air tower and provided in fluid communication with both the air tower and the compartment. The ir filter bracket includes a duct positioned adjacent the flow path of the air tower to be in fluid communication with a secondary exhaust opening of the air tower.

According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

An air cleaner including a first housing including a first suction port and a first discharge port; a first fan inside the first housing; a coupling duct on an upper portion of the first housing; a second housing including a second suction port and a second discharge port; a second fan inside the second housing; and a coupling base on a lower portion of the second housing and including a guide surface sloping outwardly in an upward direction, wherein the coupling base is separably couplable to the coupling duct. When the coupling base and coupling duct are coupled, a portion of air discharged through the first discharge port is guided by the guide surface and discharged outside of the second housing, and when the coupling base and coupling duct are separated, air is guided by the guide surface into the second housing.

A cleaner includes a suction unit, a main body including a cyclone unit for separating dust from air suctioned through the suction unit, and a dust container that stores dust separated in the cyclone unit below the cyclone unit. A filter unit is disposed inside the cyclone unit for filtering the air, and a movable unit disposed inside the cyclone unit includes a cleaning part for cleaning the outer circumference of the filter unit. An operation unit disposed outside the main body moves the movable unit and the cleaning part to remove dust from the outer surface of the filter unit.
