The invention relates to a hollow fibre separation module comprising an inlet ( 20 ) for the gas to be dried, an outlet ( 22 ) for dried gas, an access element ( 26 ) and a discharge element ( 28 ) for circulation gas, and a plurality of hollow fibres which respectively extend from the inlet ( 29 ) to the outlet ( 22 ) and comprise an inner region which communicates with the inlet ( 20 ) on one end of each hollow fibre, and with the outlet ( 22 ) on the other end of each hollow fibre. Said hollow fibres are wound up in a plurality of layers ( 40, 42, 44 ) to form a hollow cylindrical winding. Each layer ( 40, 42, 44 ) is inwardly defined by an imaginary cylinder ( 35, 36, 37 ) and has a number of hollow fibres which are wound onto said cylinder ( 35, 36, 37 ) in a helical manner with an alpha angle of inclination, are located at a distance a from each other, and are arranged on the cylinder in a homogeneously distributed manner. A layer ( 40 ) differs from an adjacent layer (e.g. 42 ) in that the fibres of one of the layers all form a plus alpha winding angle, whereas the fibres of the adjacent layers all form a minus alpha winding angle.
