Exhaust-air filter for pneumatically driven devices, which are lubricated by oil carried along in the driving air, e.g. hand tools. The driving air is fed to the device through a supply-air line (2) and the exhaust air is carried away via a hose (3) arranged coaxially with respect to the supply-air line (2). Mounted on the supply line (2) is a tube piece (7) which carries, via a connecting star (8), a hose socket (9) on which the end of the exhaust-air hose (3) is mounted. A cup (19), in the interior of which a filter insert (12) arranged concentrically about the tube piece (7) is provided and outside the filter insert (12) on the base of the cup a collecting space (14) for the deposited oil is provided, adjoins the hose socket (9). <IMAGE>
