<p>A manipulator for operation in environments involving hygienic requirements comprising a swivel for flexible transport of a gas flow. The swivel comprises a fixed part (1) and a movable part (2) journalled in the fixed part. Between the movable part and the fixed part a cavity (6) is arranged, in which the speed of the gas flow decreases. This causes the movement of particles accompanying the gas flow to stop and the particles are deposited in cavities. The fixed part (1, 5) is divisible for cleaning the inside of the swivel.</p> |
