Operating concepts made to measure Advanced and functional instruments Steel chassis finished with fire enamel and with highly resistant covers of ABS+PMMA, mounted on a steel base, with 4 rotary castors and arranged to hold the additional chest of drawers. The unit are equipped with devices enabling activation and prevent from contemporaneous activation of instruments, functions and controls of electric, pneumatic and hydraulic circuits. Control panel: display of dynamic instruments (turbine, micromotor) rotation speed, optical fibres switch-on control, reverse rotation of micromotor control, push button for sequential and continuous selection of sprays. Multi-function foot control: progressive regulation of instruments speed rotation, control of continuous or sequential spray output, chip-blower. Operating Units Lunar F are equipped with suspended hoses. The double three-jointed articulated arm allows wide horizontal motions to the instruments holder. Syringe module, air, water and spray 3 functions. Electric micromotor module, 40k GT with integrated spray, chip-blower and hydro-stop, maximum speed control. Turbine with Midwest coupling, with or without optical fibres, spray, chip-blower, hydro-stop and progressive speed. Suction with suction tube integrated into instruments holder. Nozzle to be applied directly to the micromotor.
