A filtering unit for cleaning supply air comprises a set of filters accommodated in a housing (1) and consisting of hollow bodies (10) through which supply air can flow when passing from an inlet (9) to an outlet (17) of the housing at separate ends thereof. The filter bodies (10) can each be mounted in casings (18) having greater dimensions than the filter bodies so as to define between the inner sides of the casings (18) and the outer sides of the filter bodies (10) gaps through which the supply air can flow when passing towards the respective outlet (17). The casings (18) define, together with walls (3, 4, 7, 8), a passage (20) which is isolated from the supply air and through which a fluid, such as air, having a different temperature than the supply air can flow for heating or cooling the supply air. |
