<p>The purifying appts. is intended for the removal of greasy and odorous particles from the hot, humid air derived from cooking and frying operations. It is housed in a parallelepiped envelope fitted with hoods and pipe connections. The envelope is subdivided by air deflectors into individual, superimposed air channels which guide the air to be purified through filters placed side-by-side in the channels. The air passes obliquely upwards through moist absorbent filters and then downwards through dry adsorbent filters; the filters are fixed in frames, placed in uides so that they can be withdrawn easily and replaced. The filters, in combination, remove the objectionable cooking smell in a satisfactory and inexpensive manner.</p> |
