Abstract
A filter casing for an air conditioning system includes exterior walls (1, 2, 2', 3 and 4) together with a front cover which comprises a plurality of doors (34, 35, 36, 37 and 38). The walls (1, 2, 2', 3 and 4) and doors (34, 35, 36, 37 and 38) form the casing which is divided into two compartments by parallel partitions (9, 9'). Air is drawn through an intake opening (39), through a channel (10) and sequentially passed through a temperature control apparatus (14), a filter (15) and a fan (16). The air is then transmitted through a fan outlet duct (20) to a channel (22). A plurality of absorption filter elements (23) receive the air from channel (22) and serve to remove contaminating agents. After the air is passed through the filter elements (23), it is directed into passageways (40 and 41) which are open to a rear space (42). From the rear space (42) the filtered air is exhausted from the casing through an outlet (30).
