1. A unit for purifying a gas mixture by adsorption, comprising at least one adsorber comprising at least one cluster of N identical adsorbent modules operating in parallel, where N≥2, each cluster of N adsorbent modules comprising:
a common inlet manifold comprising a straight inlet duct of axis Xe supplying N inlet nozzles Tel, where i ranges from 1 to N, respectively connected to inlets Ei, where i ranges from 1 to N, of the N modules of said cluster,
a common outlet manifold comprising a straight outlet duct of axis Xs collecting the flow leaving N outlet nozzles Tsi, where i ranges from 1 to N, respectively connected to outlets Si, where i ranges from 1 to N, of the N modules of said cluster,, wherein:
the axes Xe and Xs are substantially coincident,
the N inlets Ei of the N modules are substantially situated on a first circle centered on the axis Xe or Xs,
the N outlets Si of the N modules are substantially situated on a second circle centered on the axis Xe or Xs,
the N inlet nozzles Tei are of substantially identical geometries, and, the N outlet nozzles Tsi are of substantially identical geometries, wherein the unit is a unit of the O2 VSA or O2 MPSA type comprising 1 to 4 adsorbers comprising 1 to 4 clusters of 3 to 6 modules.
