Exhaust hood, of the type that is mounted in the kitchens to carry out the extraction of fumes and vapors, essentially characterized in that its base or lower surface is blocked, at least in an important part of its extension, by a smooth iron, being made suction exclusively through the perimetric gap caused by the gap between this plate and the body of the bell and/or through a small number of grooves provided therein; all in such a way that the reduced total area of the suction opening results in a very high suction velocity, resulting in the vertical projection of the apparatus a moving air curtain, which prevents the dispersion of fumes and vapors.
