The invention relates to an installation ( 1 ) for guiding a gas for devices ( 44 ) used to treat granular products ( 56 ) by drying, film-coating or coating, especially an air intake unit, comprising a central distribution channel ( 2 ) that can be connected to a gas supplying device and is connected to outlets ( 6.1, 6. n) for the gas, that are arranged at a distance from the central distribution channel in an axial direction, by means of connection channels ( 3, 4 ). According to the invention, the installation comprises a functional channel ( 5 ) which is arranged at a distance from the distribution channel ( 2 ) and has a plurality of outlets ( 6.1, 6. n). Said functional channel comprises at least two axially interspaced inlet regions ( 11, 12 ). Each inlet region ( 11, 12 ) is connected to the distribution channel ( 2 ) by means of a connection channel ( 3, 4 ). The outlets ( 6.1, 6. n) are arranged, in the axial direction on the functional channel ( 5 ), between the mouth of two connection channels ( 3, 4 ), which are adjacently arranged in the axial direction, in the functional channel ( 5 ).
