Device for abating air-borne microbiological components

A device (100) for abating microbiological components present in an air flow, comprising:

• a main body (101), said main body (101) being provided, on its surface, with a first aperture (102) and a second aperture (103);
• a plurality of shelves (110a, 110b, 110c, 110d) positioned within said main body (101), each shelf (110a, 110b, 110c, 110d) being provided with at least one through hole (111a, 111b, 111c, 111d);
• a plurality of UV electromagnetic sources (121a, 121b, 121c, . . . , 121n) arranged between said shelves so as to emit UV light within said main body (101);
• a first fan (131), connected to said first aperture (102) and adapted to suck air into said main body (101);
• a control unit (140) configured for driving said plurality of UV electromagnetic sources (121a, 121b, 121c) and said suction fan (131);
• wherein said first aperture (102) and said second aperture (103) and each hole (111a, 111b, 111c, 111d) of each shelf (110a, 110b, 110c, 110d) are in fluidic communication;
• wherein said main body (101) has a minimum volume Vem given by the following relation:
• V
• em
• =
• D
• ⁢
• 1
• I
• ⁢
• nV
• where D is the abatement dose necessary for abating a microbiological species by 99%, I is the mean intensity of the electromagnetic field of said plurality of UV electromagnetic sources (121a, 121b, 121c), and nV is the aeraulic capacity of the device (100).
