Gauge Panel
1
st
stage pressure gauge
(1)
The
(1)
gauge indicates the pressure inside the 1
st
compression stage. If the Pressure is not
between 45 psi (3 bar) and 60 psi (4 bar) switch off the compressor and contact Nuvair.
2
nd
stage pressure gauge
(2)
The
(2)
gauge indicates the pressure inside the 2
nd
compression stage. If the Pressure is not
between 230 psi (16 bar) and 290 psi (20 bar) switch off the compressor and contact Nuvair.
3
rd
stage pressure gauge
(3)
The
(3)
gauge indicates the pressure inside the 3
rd
compression stage. If the Pressure is not
between 940 psi (65 bar) and 1200 psi (80 bar) switch off the compressor and contact Nuvair.
4
th
stage pressure gauge / Working Pressure Gauge
(4)
This
(4)
gauge indicates the pressure as it exits the compressor. If the Pressure fails to reach
the pressure set on the pressure switch, switch off the compressor and contact Nuvair.
Fill Pressure Gauge

Overpressure Safety Valves
Each stage of the compressor is equipped with an overpressure relief valve to ensure that the
unit will not be damaged in the event that the pressure shutoff switch fails to work. The final
stage valve is pre-adjusted to 3200 psi (225 bar), 4300psi (300bar), 4700psi (330bar) or 6000
psi (425 bar) dependent on the final pressure specified when the unit was ordered.
Tampering with the safety valve to increase the pressure setting is strictly forbidden.
Tampering with the safety valve can seriously damage the compressor, cause serious injury
to personnel and renders the warranty null and void.
