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 filtering body, in particular for a rotary separator, extends about an axis and has a two opposite axial faces, a radially outer surface and a radially inner surface; the filtering body comprises a filtering net constituted by filaments defining a plurality of pores between them; a frame, which is defined by non-porous solid elements, supports the filtering net and made in one piece with a filtering net; the frame has at least one element arranged in an intermediate radial position between the radially outer and inner surfaces.

A manufacturing method enables the obtainment of a functional part essentially formed in a metallic material, all or part of the functional part delimiting a filtering medium permeable to a fluid and delimiting first and second main faces for a preferred circulation of said gas through the filtering medium. The method includes a main phase consisting of an additive manufacturing method in successive passes from a support tray. Each pass comprises the deposition of at least one layer of said metallic material, the deposited material adhering to the metallic material of at least one layer deposited before. The deposition is controlled at each pass such that the stack of the metallic material deposited during the successive passes constitutes the functional part. The filtering medium includes a coalescent network of connecting strands interconnected according to a three-dimensional spatial distribution between the first and second main faces.

A filtration filter that includes a filter section having a plurality of through-holes passing through a first main surface and constructed such that objects to be filtered contained in a liquid are captured and a second main surface opposite the first main surface; and a frame section surrounding an outer periphery of the filter section, wherein a first film thickness at a center of the filter section is larger than a second film thickness of the filter section at a position closer to the frame section than the center of the filter section.
