FIELD: ventilation.
SUBSTANCE: invention relates to laboratory exhaust devices intended for cleaning air in the operating room. Laboratory exhaust device is made with a working area (13) and ventilation system (26) to create air flow (27) or with inlet (63) for air flow (27) for removal of gases and/or solid particles (48) of the working area (13). There is at least one surface limiting the working area (13). Device contains charging devices (30, 87, 88) for ionisation of air flow (27) and/or for electrostatic charging of at least one above-mentioned surface. Charging devices (30, 87, 88) are made for the purpose of neutralisation of air flow (27) and/or at least one above-mentioned surface.
EFFECT: provides for removal of gases and/or solid particles from working area of laboratory device.
