The autoclavable HVE Air Protect XL Plus from Air Techniques offers effective protection against aerosols. Its ergonomic design and the rotating, protective shield are unique. The shield can be effortlessly adapted to any treatment situation in which spray mist is generated and is particularly suited for treatments with prophy powders preventing irritation of the mucous membranes. The large opening through the protective shield allows for more aerosols and prophylaxis powder to be removed making it easy to use for treatments without an assistant. Suction comfort is increased even on rubber dam applications. Protective secondary air inlets provide the best possible protection against backflow from the suction system.
