A device for reducing evaporation of volatile organic compounds (VOC) during filling of a substantially liquid petroleum product into a storage and/or transportation tank ( 18 ) via a down pipe ( 14 ), wherein the down pipe ( 14 ), which has a non-constricted flow-section, is provided with an inlet ( 22 ) for gas at its upper portion, the inlet ( 22 ) being arranged to enable inflow of gas due to the underpressure being formed in the upper portion of the down pipe ( 14 ) when the petroleum product flows down through the down pipe ( 14 ).
