Consult the Vanair

Service Department for issues
relating to adjustment of motor speed.
6.6.13 ADJUSTING THE PRESSURE SETTING
The
Cut-in pressure
is defined as the pressure in which
the compressor starts pumping. Anytime the pressure in
the tank falls below this pressure the compressor is
allowed to start pumping.
NOTE
Do not tamper with the flow control
setting to increase the maximum motor
speed. Overspeed is hazardous and will
void the motor warranty.
WARNING
The compressor cut-in/cut-out pressures
have been factory-adjusted within the
limits of the compressor manufacturer.
The maximum pressure limit of the
compressor is 175 psi. Pressure should
never be allowed to go beyond this limit
or what has been set by local laws and
regulators. This system will disengage
the clutch at 185 psi. A 200 psi safety
relief valve is located on the air tank to
prevent over pressurizing the system.
