Face plate portion may include flange flex grooves formed in an attachment flange, allowing walls to deflect independently from corners, such that the flange flex grooves allow the attachment flange to flex outward from the outer surface. Base plate portion may include alignment ribs extending outward from the outer surface, such that the flange flex grooves formed in the attachment flange interface with the alignment ribs formed on the base plate portion.

An air cleaner includes a housing including a first opening configured to absorb outside air, a second opening configured to discharge the air outside, and a housing body having an internal flow path connecting the first opening and the second opening, a blower unit including a blowing fan configured to blow air accommodated in the internal flow path toward the second opening, and a driving motor disposed between the first opening and the blowing fan and detachably shaft-coupled to the blowing fan, and installed in the internal flow path, a filter installed in the internal flow path and configured to purify air absorbed through the first opening, and a discharge unit including a discharge grille having a plurality of discharge holes formed to allow air reaching the second opening to pass therethrough and detachably coupled to the second opening. Accordingly, the discharge grille for discharging air purified by the filter to the outside is separated from the opening of the housing to open the internal flow path in which the blowing fan and other internal components are installed, and thus cleaning, repair, and other tasks on the internal flow path and internal components are easily performed through the opening from which the discharge grille is separated.

A ventilation louver (10) includes a first plate (52) defining a first opening (74) therein for permitting fluid flow along a first direction (128), a second plate (54) defining a vane (82) therein, the vane at least partially covering the first opening and directing the fluid flow along a second direction (130), non-parallel to the first direction, and a third plate (56) defining a louvered opening (108) therein wherein the louvered opening directs fluid flow along a third direction (138), non-parallel to both the first direction and the second direction. In a non-limiting example, the ventilation louver may be disposed in a belly fairing of an aircraft.

Disclosed herein is an air conditioner comprising, a housing in which an outlet is formed, a heat exchanger positioned inside the housing, and a fan positioned behind the heat exchanger. The fan configured to blow air to the heat exchanger. And a filter assembly coupled to the housing. The filter assembly configured to filter air entering the fan. The filter assembly covering a rear portion of the fan.

A venting system includes a frame and a register cover attached to the frame. The register cover includes a plurality of alternating open areas and air diverting fins vertically orientated on the register cover. Three open areas among the plurality of open areas are disposed proximate a central portion of the register cover. A tool engagement feature is located at the central portion of the register cover and includes a plurality of concave surfaces formed on at least four of the air diverting fins among the plurality of air diverting fins. The tool engagement feature further includes a forwardly projecting knuckle arranged at a center of each of the three open areas disposed at the central portion of the register cover.

A retractable structure for air-conditioning vent has a retractable mechanism capable of retractably installing a vane into an installing hole of a main body. The retractable mechanism includes a plurality of connecting plates on the main body, and an end of the connecting plates is limited on the main body, and the other end of the connecting plate is passed through a plug hole formed on the vane, and each connecting plate has a bracket on a corresponding side, and a middle portion of the bracket is coupled to the connecting plate, and a first bracket portion and a second bracket portion disposed on both sides of the middle portion of the bracket respectively are outwardly protruded and then inwardly bent to form a stopper portion to stop the plug hole from automatically sliding down.

A frame assembly for an air distribution system includes a damper assembly, a louver assembly, and a screen frame. Air flows through the damper assembly and the louver assembly, where the damper assembly terminates in a first flange and the louver terminates in a second flange. The first flange and the second flange are coupled to one another about a screen frame such that the screen frame is captured by abutting the first flange and the second flange.

The systems and methods disclosed relate to an air intake assembly, wherein the air intake assembly comprises: a frame comprising a plurality of openings, wherein each one of the plurality of openings comprises a V-shaped cross-section. The air intake assembly further comprises a plurality of slats, wherein each one of the plurality of slats comprises a V-shaped cross-section. The air intake assembly further comprises a stiffener configured to provide structural support to the plurality of slats, wherein the stiffener is disposed within an interior of the frame. The plurality of slats are disposed within the frame through the plurality of openings of the frame and through the stiffener.

Provided is a fin for register that can firmly fix a mounting member to a fin body. A horizontal fin includes a plate-shaped fin body and a mounting member mounted to a downstream side edge part of the fin body. The mounting member has a curved shape to cover the downstream side edge part of the fin body. The downstream side edge part includes a first recessed part at a tip part on a front side in a longitudinal direction. The first recessed part is formed by recessing the tip part of the downstream side edge part. The downstream side edge part and the mounting member are fixed to each other by an adhesive filled in the first recessed part.
