Abstract: A fan (1) for a smoke and/or vapor extraction system that includes an impeller (3) located within a diffuser or volute (2), the impeller (3) being driven by an electric motor (24); the impeller (3) having a body (20) having a flat part (21) from which a plurality of radially arranged blades (33) extend; these blades are separated from each other by a variable distance based on a periodic function. In addition to this, the diffuser (2) has an air delivery or discharge conduit (5) having a cross-section increasing from an inlet to its outlet (6).

Abstract: An extractor hood capable of extracting fumes and/or vapors being generated on a cooking surface, the hood including a first portion (2) integral with a wall (3) of the room where the cooking surface is located, a second portion (4), spaced apart from the first and close to the cooking surface, and a support connection (50) capable of securing the first portion (2) to the second portion (4), the second portion containing a fan (5) capable of extracting fumes and/or vapors from the cooking surface when the hood (1) is in use. The first portion (2) includes an autonomous extraction device capable of extracting fumes and/or vapors exiting the second portion (4) and extracted from the cooking surface by the fan (5) present in the second portion (4), the hood having no connecting tube between the second portion (2) and the first portion (4).

Abstract: An extractor hood (1) with a body (2) which is hollow in its interior (at 15), provided with a lateral opening (8) and containing in its cavity (15) a fan (16) which can aspirate from the lateral opening (8) fumes and/or vapors generated by an underlying hob of a kitchen, the body (2) having opposite surfaces (5, 6) with a larger area, connected by walls or surfaces (10, 11, 12, 13) with a smaller area, a first one (5) of the surfaces (5, 6) with the larger area being placed on a vertical wall (2) of said kitchen, the second surface (6) with the larger area containing the aforementioned lateral opening (8), and in front of this opening (8) there being a flat panel (23) placed spaced from this second larger surface. This flat panel (23) is parallel to the second surface (6), including when the hood (1) is in use.
