The present invention relates to a fluid separation device (10) for separating fluid, oil and oil spray from a gas. This fluid separation device (10) comprises a base carrier (21) in which fluid separator elements (20) in the form of flow-through tubes with worm-like segments (23) arranged therein, are integrated. The worm-like segments (23) at the same time form spiral flow paths (25) for the gas. They have a maximal length of half a pitch of the worm-like segment (23) so that the base carrier (21) together with the associated fluid separator elements (20) may be formed as one piece. Several base carriers may be arranged one after the other in a manner such that individual fluid separator elements of various base carriers form a common flow path for the gas.
