1. GENERAL INFORMATION
Linea Esse offers a wide range of instruments to be positioned in the four existing housings.
Linea Esse is available in two versions, with a spittoon unit suspended over the chair or on the floor.
Its special kinematism allows for reduced vertical travel of the instrument return arms, total self-balancing in the
maximum extraction position and maximum freedom of the feed tubes in all directions.
All the top part of the spittoon unit is painted resin, the basin is ceramic and has no interstices for better cleaning and
increased hygiene. The cannulae to wash the basin and fill the cup can be easily removed and are autoclavable.
The high-speed suction tubes and connections are easy to remove for disinfection purposes. At the same time, the filter
can be extracted in an easy and hygienic manner too.
Linea Esse can be combined with patient chairs Moon, Arcadia EXT, Arcadia P and Swan, compliant with Directive
93/42/EC and its successive amendments and additions produced by O.M.S.
The CE 0051 certification applies to Linea Esse only.
