This invention concerns a device in gas transfer equipment, particularly in one for the transfer of hazardous gases out of work places, and concerns the connection of parts interacting with each other in the equipment (1), so that the equipment (1) can be set up in several different ways, depending on how and/or where it is to be applied, whereby the equipment (1) has a tube shaped bracket (2), which partly is designed to connect to a stand (3), partly has a fixed end (4) in which is fitted an adjustable bearer arm system(5) and a gas lead (6) surrounding the bearer arm system(5), and partly has a connection end (7)for connecting to other parts, within the gas transport equipment e.g. a gas lead (8), a fan or a valve.To enable a device, of this type to be used for a number of different applications, without needing new parts for every new application, the tube shaped bracket (2) is movable relative to the stand (3) with either the fixed end (4) pointed in one direction or in the opposite direction, and the fixed end (4) is shaped to allow the placing of the bearer arm system (5) in different start positions relative to the bracket (2).<IMAGE> |
