Abstract:
A diffuser head and an air cleaning apparatus comprising same. A diffuser head (1;11,18;23;31;43) is adapted for local application of purified air to a target (39), which diffuser has a main body (8;12;20;24) with an air inlet surface (3;15;28;33), that has a first area (A1), towards an air outlet surface (4;16;19;26;34), that has a second area (A2) that is greater than the first area (A1). The main body (8;12;20;24) has a plurality of continuous expanding air ducts (2;14;22;27;32) extending lengthwise between the air inlet surface (3;15;28;33) and the air outlet surface (4;16;19;26;34), wherein an air duct (2;14;22;27;32) has a third cross-sectional area (A) that increases continuously from an air duct inlet (5) at said air inlet surface (3;15;28;33) towards an air duct outlet (6;22) at said air outlet surface (4;16;19;26;34). If a filter means (36) is provided at the air inlet surface (3;15;28;33) The diffuser head can be used in an air cleaning apparatus that has a pump means for intake of air from the surrounding environment.
