Air Supply

Table 2: Air Supply
Minimum Input 1,5 Bar (22 PSI)
Pressure
Maximum Input Single Acting Relay – 6,2 Bar (90 PSI)
Pressure
Double Acting Relay – 10,3 Bar (150 PSI)
(Set supply pressure as low as possible
for maximum relay life.)
Air Supply Quality The air supply must be free from moisture,
oil and dust by conforming to the ISA
7.0.01 standard. (A dew point at least 18
degrees Fahrenheit below ambient
temperature, particle size below five
microns—one micron recommended—and
oil content not to exceed one part per
million).
Operating Humidity 0 - 100% non-condensing
Acceptable Supply Air, sweet natural gas up to 5 bar, nitrogen
Gasses and CO2 are acceptable supply gasses.
Sour natural gas is not acceptable.
Air Consumption Single Acting Relay –
0.069 Nm³/h @ 1,5 bar
(0.041 SCFM @ 22 PSI)
0.082 Nm³/h @ 4,1 bar
(0.048 SCFM @ 60 PSI)
Double Acting Relay –
0.297 Nm³/h @ 1,5 bar
(0.175 SCFM @ 22 PSI)
0.637 Nm³/h @ 4,1 bar
(0.375 SCFM @ 60 PSI)
