• SAFETY VALVE (10): a certified safety valve (set to 10.5 bar), installed to the pneumatic system, under the pressure
switch. It tackles over-pressure in the instance where, owing to anomalies, the pressure switch does not function. Safety
valve intervention ensures the operator switches off the appliance and requests the support of maintenance persons.
• PRESSURE SWITCh (2): an electro-pneumatic device (set to a minimum of 7 bar and a maximum of 10 bar) installed to
the pneumatic system. It serves to control the automatic start-up of the appliance when the operating pressure comes
down to 7 bar and the automatic close-down when the pressure reaches 10 bar.
• FIxED COOLING FAN PROTECTIVE NET (19): fixed protection made of plastic attached using screws fixed to the twin
cylinder pump system base. It serves to stop accidental contact with the cooling fan when in motion.
• TANk PRESSURE GAUGE (15): a measuring device installed to the appliance tank. It displays the compressed air pres-
sure inside the tank.
• OUTLET PRESSURE GAUGE (8): a measuring device installed to the appliance pneumatic system above the air outlet
spigot. It displays the outlet pressure, which can be adjusted using the relative pressure regulator (0÷10 bar) (7).
