<p>Non-toxic, air purifier for fixing in ducts, ventilator openings, on walls etc. is of the type which diffuses a disinfectant, deodorising vapour into the atmos. and does not require any movements or any power for circulating fans etc.. The vapour is now produced by sublimation of a solid block of disinfectant material. The block is housed in a box which has an open grill in one side to allow vapour to escape. The box is easily fixed to a wall by means of a double-sided, pressure-sensitive, adhesive patch on an external face of the box. Device can be installed by unskilled labour, on horizontal, vertical or inclined surfaces. Vapour diffusion proceeds continuously.</p> |
