A louver assembly includes a support, a plurality of blades, and an insert. The support extends along a length and includes a plurality of slots formed therethrough. Additionally, each louver blade of the plurality of louver blades includes a retention aperture formed therethrough, where each louver blade of the plurality of louver blades extends through a respective blade aperture of the plurality of blade apertures. Moreover, the insert extends through the retention aperture of each louver blade of the plurality of louver blades.

The ceiling concealed air-conditioning apparatus includes: a body containing a heat exchanger, a fan and an opening port; a decorative panel disposed below the body and configured to cover a periphery of the opening port; and a suction grille including, a rotary shaft attachable to the decorative panel and being configured to cover the opening port, wherein the suction grille includes: a locking element mounted on the suction grille so that it can slide and configured to be locked with the decorative panel; plate springs on respective sides of the locking element perpendicular to a sliding direction of the locking element and extending vertically in opposite directions; and spring supports configured to support both end faces of the respective plate springs at different positions, the plate springs include a long plate spring and a short plate spring placed such that the long plate spring engages the decorative panel first.

An exhaust vent cap assembly can be installed in a roof deck of a building to allow a one-time connection of the insulated duct to the roof from exhaust fans within the building.

An insert for an air intake of a suction duct, the insert including an inner portion configured to extend within the suction duct, a mating portion configured for sealingly engaging the air intake, and an outer portion configured for extending outside of the suction duct. The inner portion includes a conduit having a central axis extending along an inlet direction at the inlet end and along an outlet direction at the outlet end, the inlet and outlet directions being non-parallel. The outlet end has a smaller cross-sectional area than that of the suction duct. The insert includes an inlet in fluid communication with the inlet end of the conduit. The outer portion includes a curved lip surrounding at least part of an inlet opening of the inlet, the lip configured to direct a flow into the inlet opening and toward the inlet end of the conduit.

The Frameless Flush Mount Floor Vent Device is removeable floor register vent with backing material removed sufficient to allow an attached support plate remaining flush to matching surrounding floor resting on existing subfloor.

A vent cover assembly to cover an opening in a crawl space vent includes a vent cover having upper and lower surfaces, an outer perimeter and a planar clip. The vent cover includes a slit positioned through the upper and lower surfaces of the vent cover to receive the clip. The clip has a ring portion and a first leg and a second leg extending therefrom. The first and second legs are configured to be slidably inserted through the slit of the vent cover. The first and second legs of the clip are positioned and configured to receive therebetween a portion of a vertically positioned central wall of the crawl space vent. The central wall is frictionally griped between the first and second legs of the clip, and the inner surface of the vent cover is simultaneously positioned over an outer perimeter of the vent to close the vent.

Disclosed herein is an air conditioner including a suction panel which includes a suction port through which air is suctioned in inside a housing. The suction panel is formed to rotate with an axial direction of an air blowing fan or a direction perpendicular to the axial direction of the air blowing fan as a rotation axis to be coupled with or separated from the housing. Accordingly, a user may easily and intuitively separate the suction panel and falling of the suction panel, which may occur when the suction panel is separated, may be effectively reduced using a supporting unit disposed at the suction panel. Also, the housing and cover members which cover an outer perimeter of a lower portion of the housing may be coupled with each other by pressurizing the cover members toward the housing, thereby allowing the user to easily coupled the cover members.

A friction fit vent cover is configured for installation into a ventilation opening in a building surface. The friction fit vent cover includes a main frame, a pair of side panels and at least one friction fit assembly. The at least one friction fit assembly includes a spring, preferably a compression spring, which is able to be moved into an energized position (such as a compressed position). The pair of side panels are in communication with the spring and are able to slide relative to the main frame. In use, the pair of side panels are frictionally held against bordering sides of a ventilation opening when the spring is in the energized position, thereby holding the friction fit vent cover therewithin.

The present invention relates to a reliable, efficient, and low cost ventilation system for storage covers that improves the distribution of air flow and improves aeration of the particulate material and the method of installing the same.

A generally planar blank made, for example, from sheet metal can be formed into a vent protector that can be mounted to an outer wall of a structure over the exhaust aperture of a vent to inhibit vertebrate wildlife from entering the vent. The vent protector forms an enclosure for receiving vent flaps that may extend outwardly from the wall of the structure.
