Allows the operator to shut-off the air from the
tank to the flexible hose.

air pressure in the tank. When the air pressure
in the tank drops to 175 10 psi (12.3 0.70
kgs/cm2) the switch is actuated and causes the
motor starter to start the motor. When the air
pressure in the tank is raised to 200 0, -10 psi
(14.1 0, -0.70 kgs/cm2) the switch opens and
causes the motor starter to shut off the motor.

Safety Relief Valve
Allows air to escape when pressure exceeds
3
200 psi (14.1 kgs/cm ).
4
Air Pressure Gage
Provides an indication of air pressure in the
tank. The gage reads 0 to 300 psig.
