  • Air exhausting means
    Patent number: 4811724
    Abstract: The present invention concerns an air exhausting device, intended primarily for catering industry kitchens or equivalent. The air exhausting device comprises an outer housing, an exhaust chamber with at least one air aperture or grease filter unit, a collecting chamber for gaseous impurities and a blow chamber. The blow apertures of the blow chamber of the air exhausting device are disposed to produce a blow jet which induces a secondary air jet, which has on all sides of the blow apertures been arranged to act on its entirety in the proximity effect area. Above the blow apertures of the blow chamber has been disposed a guide baffle, arranged to direct the blow jet towards the grease filters to that the maximally efficient starting impulse of the blow jet is achieved, this impulse being arranged to substantially die out before arriving at the grease filter.
