Abstract
A filter device for a fume extraction device includes at least two filter elements arranged at an angle relative to one another, and a holding frame for holding the at least two filter elements. An edge of one of the at least two filter elements lies adjacent to an edge of the other one of the at least two filter element. Each of the at least two filter elements has a surface with a variable distance between opposite outer faces of the filter element.
Claims23
A filter device for a fume extraction device, said filter device comprising:
- at least two filter elements arranged at an angle relative to one another, with an edge of one of the at least two filter elements lying adjacent to an edge of the other one of the at least two filter element, each of the at least two filter elements having a surface with a variable distance between opposite outer faces of the filter element;
- and
- a holding frame for holding the at least two filter elements,
- wherein the distance between the opposite outer faces of each of the at least two filter elements from one edge of the filter element in a direction of an opposite edge increases from a minimum to a maximum and from the maximum to the opposite edge decreases to the minimum, and
- wherein the filter element has a diamond-shaped cross-section.
A fume extraction device, comprising:
- a fume extraction housing having an upper face with a suction opening;
- a fan arranged offset downward relative to the suction opening;
- and
- a filter device comprising at least two filter elements arranged at an angle relative to one another, with an edge of one of the at least two filter elements lying adjacent to an edge of the other one of the at least two filter element, each of the at least two filter elements having a surface with a variable distance between opposite outer faces of the filter element, and a holding frame for holding the at least two filter elements,
- wherein the distance between the opposite outer faces of each of the at least two filter elements from one edge of the filter element in a direction of an opposite edge increases from a minimum to a maximum and from the maximum to the opposite edge decreases to the minimum, and
- wherein the filter element has a diamond-shaped cross-section.
A fume extraction device, comprising:
- a fume extraction housing having an upper face with a suction opening;
- a fan arranged offset downward relative to the suction opening;
- and
- a filter device comprising at least two filter elements arranged at an angle relative to one another, with an edge of one of the at least two filter elements lying adjacent to an edge of the other one of the at least two filter element, each of the at least two filter elements having a surface with a variable distance between opposite outer faces of the filter element, and a holding frame for holding the at least two filter elements,
- wherein the suction opening has a rectangular, elongated cross-section and preferably has a width of 150 mm.
