The purpose of the Moblvac®III-cs is to perform all routine constant suctioning procedures. These
may include tracheal and oral aspiration, wound and thoracic drainage. The Moblvac®III-cs is also
ideal for use within the G.I. lab as well as for backup suction in the O.R. and E.R. departments.
The Ohio Medical Moblvac®III-cs is a constant suction unit designed for use in the hospital, surgery
center, and physicians offices. Because of the Moblvac’s constant suction capacities are driven by a
fan cooled, rotary carbon vane pump. It comes equipped with a disposable exhaust filter, an in-line
suction filter with 14” of tubing, a disposable 1200cc collection canister with mounting bracket, and a
preventative maintenance kit.
