A diffuser () for a fan () of axial, radial or diagonal type of construction, has an inlet opening () and having an outlet opening () for a gaseous medium which flows through a diffuser interior (I), which is enclosed by an outer housing (), in an axially oriented main flow direction (S) from the inlet opening () to the outlet opening (). The cross section of the diffuser interior (I) increases from the cross section () of the inlet opening to the cross section () of the outlet opening (), wherein the outer housing () forms an outer diffuser part (AD) which delimits the diffuser interior (I) to the outside. Along the main flow direction (S), the cross section of the outer diffuser part (AD) changes from a circular cross section () at the inlet opening () to a non-circular cross section () at the outlet opening ().
