The DeVilbiss 7305 Series Homecare Suction Unit is a compact medical suctioning device which has been designed for reliable, portable operation. Because of the small size, light weight and DC operation, the DeVilbiss 7305 Suction Unit is ideal for providing suction in the home, or on the go with the DC cord. The 7305 P-D includes a rechargeable battery. Two collection bottle options give the choice between the standard 800 ml disposable canister and optional long-term reusable 1,200 ml canister.
