Electronic Phlegm Suction Machine from Life-Line® Adopts a highly efficient plunger pump that is well lubricated and has a long life. The suction pump is uni-directional, without generating positive pressure: it is designed to have an excess flow protection device to prevent the liquid from entering into the suction pump. The hand switch and foot switch are connected with each other in a parallel manner: they can be chosen and used at one’s will. The foot switch is for low pressure control. Max vacuum: ≥0.75 MPa Flow rate:≥18 L/min Storage bottle: 1000 ml×1
