The filter comprises further a downward conduit 5, which at its upper end is connected to the inlet 1 via a slot 4, arranged in the lower part of the inlet 1. The downward conduit 5 is at its lower end connected to a detachable condensate container for collection of condensed moisture. A particle filtering unit comprises a transport duct 9, which at one end is connected to the inlet 1, after the slot 4. The other end of the transport duct it is connected a substantially cylinder-shaped and vertical cyclone (10), and the cyclone is at its lower end connected to a detachable particle container for collection of particles. <IMAGE> |
