Abstract: A cyclonic separation apparatus includes an outer wall, an inner wall and a cyclonic chamber defined between the outer wall and inner wall. A section of the surfaces of both the outer wall and the inner wall are flattened. The inner wall and the outer wall are also concentrically arranged. During use a fluid moving around the cyclonic chamber flows between a curved passage and a flattened passage of the cyclonic chamber.
