The tank (5) has a bottom wall (5a) under which a turbine (6) of an aspiration unit is placed, where the tank is placed on a frame composed of lateral pieces. A horizontal tubular portion of a suction duct of the aspiration unit forms a lower branch (8c) on which the tank is arranged, where the tank is placed between lateral branches (8a, 8b) of the duct. The lateral branches extend respectively along lateral walls (5c, 5d) of the tank for rejoining an upper part and cooperating with a particle filtration and separation unit for filtration and separation of particles inside the tank. The particle filtration and separation unit is composed of a central deflector connected to accordion shaped lateral grids coated with an anti-adhesive material. |
