Abstract: The invention relates to a blow-out grid, the peripheral form and dimensions of which correspond to an elongate form of a blow-out opening of an air curtain device. This blow-out grid comprises slats which extend in use longitudinally and transversely relative to the lengthwise direction of the blow-out grid and which guide in a desired uniform direction respective transversely and longitudinally diverging components of an airflow passing therethrough. The invention further relates to an air curtain device, comprising: a housing; means generating an airflow in the housing; an elongate blow-out opening with an inner peripheral form; a channel between the means generating an airflow and the blow-out opening; and a blow-out grid arranged in the blow-out opening and having a peripheral form and dimensions corresponding to the elongate form of the blow-out opening, and wherein the blow-out grid is one from the group comprising blow-out grids.

Abstract: The invention relates to a vehicle for transporting products, comprising: a truck; a cargo space arranged on the truck for receiving the products during transport, with at least one access door; and an air curtain device close to the access door which, at least in the opened situation of the access door, generates an air curtain along a door opening of the access door, wherein the air curtain device comprises at least one fan, with an air feed duct which connects the fan to the exterior of the cargo space to supply outside air for the air curtain.
