Gentec's Lubricated Rotary Vane Systems are medical vacuum systems commonly used for medical constructions which are very reliable and easy to maintain. The rotary vane pumps use oil to "lubricate" or create the seal between the tip of the vanes and the pump housing. Main features include: long vane life, low maintenance and noise level, air-cooled design, no rust and scale problems and low operating costs (no water and sewage costs).
