<p>An installation for filtering air comprises a plurality of cells (10) in parallel and each including an inlet (26), at least one filter (20), and an outlet (18, 34), the inlets being connected to an inlet manifold (24), and means being provided (35; 37) for causing the gas to flow through said cells. The installation further comprises: a first shutter (28) in each inlet; a dust-removal manifold (40) connected to the bottom of each cell via a dust-removal passage (14) in which a second shutter (30) is provided; and means (38, 35 min ) for establishing a backflow of gas through each cell. For filtering, the first shutter is open and the second shutter is closed. For un clogging, the first shutter is closed and the second shutter is open, and the backflow means unclog particles and remove them. <IMAGE></p> |
