Abstract (en)

[origin: EP0288351A2] The air cleaner for buildings is of the kind comprising a substantially parallelipipedic box 1 which must be placed high up in premises A and has a front 2, a top surface 3 and a bottom surface 5, which box 1 has an air inlet, an air outlet, and an ionisation chamber 30 having conductive internal walls and containing a conductive wire 38 which is to carry a high tension electrical current, the air being passed from the inlet to the outlet by at least one mechanism such as a fan 20-21. It is characterised in that the air inlet is situated on the front 2 and the outlet on the bottom surface 5 of the box 1, the ionisation chamber 30 being formed by two lateral end plates 33 and by a curved wall 31 which has, beginning at the inlet, an ascending portion, a top arch 36 having a centre of curvature substantially coincident with the position of the conductive wire 30, and a descending portion 37 combined with a transverse deflector 32 which extends from the bottom of the box 1 towards the centre of curvature of the arch 36 as far as a peak situated along a line 39 higher than the lower edge 34 of the ascending portion. <IMAGE>
