Specifications Welcome to the New Series 5: treatment units with suspended chair and vertical elevation. Open space under the chair, without obstacles, allowing greater leg-room for dentists and their assistants. Its ergonomic design means all the components are integrated and coordinated together, so that any dental treatment can be done as comfortably and efficiently as possible. The technologically advanced, customisable unique look is transferred into the image of the treatment room. And, of course, made of aluminium.
