Description of the electrical parts

This unit is equipped with a mains socket with fuses incor-

porated. The main switch ON/OFF is placed on the back

side of the unit.

The mains voltage (high voltage of 110, 220 or 240 V AC)

is converted into 24V AC (low voltage), by an internal trans-

former, to supply all the electrical components of the unit.

AirFlow®S1

Description of the hydraulic parts

AirFlow® S1 is equipped with a water lter at the entrance

of the water supply. Water circuit is made by blue hoses.

On the AirFlow®unit, the water passes through a water

lter then though a water regulator allowing the regulation

of the ow, and goes into the pneumatic module driven by

the electrovalve, the heater and the polisher handpiece via

the handpiece cord.
