<p>An air flow is passed through fibre flock material, to clean it by removing dirt and dust, the flock material being placed on a porous supporting surface. Jets are placed under the supporting table surface to deliver compressed air through the support openings and through the flock material. Heavy dirt particles drop down through the openings in the supporting surface, while light dirt and dust is extracted by an upper suction unit. As the flock material is not pressed against a surface by suction, it remains loose and manageable, while the dirt and dust is sepd. and removed easily.</p> |
