An evacuating kit (10) having a puncturing device (14) for evacuating aerosol cans into a drum (12), on which the puncturing device is mounted at a first bung hole (36), also includes a filter canister (16) for being coupled to a second bung hole (77) of the drum by a flexible transfer hose (20) so that the filter canister can be supported by a floor supporting the drum. The puncturing device further includes a valve at a second end (32) of a tubular wall (23) of a housing (22) of the puncturing device with a valve poppet (50) positioned beyond the second end for opening and closing a second-end opening (28) using the second end of the housing as a valve seat.
