The invention claims a process and a filtering device for continuous separation of particles from in a conduit flowing fluid (3), at which the fluid on entering the apparatus is given a rotational movement by means of a rotation inducing member (7) and that the flow of the fluid is caused to pass through a filter which is arranged at the downstream end of the apparatus, at which the filter comprises a filtering surface (20.1) and a filter surface (20.2), the filtering surface extending along the rotational axis of the fluid and the filter surface being so placed as to form a downstream barrier for the non-filter fluid, whereby in the event of a sudden increase of pressure in the fluid, the filter surface during an initial stage allows a potent rotational movement to build up synchronously with the separation of the torn-away particles being effected against the filter surface (20.2), whereby the rotational movement of the fluid is given enough time to stabilize and the torn-away particles are forced away from the filtering surface and whereby said particles by the movement of the liquid concurrently are moved in the longitudinal direction of the device towards the filter surface. |
