2.3 Air Supply
Table 3: Air Supply
Minimum Input Pressure
1.5 Bar (22 PSI)
Maximum Input Pressure
Single Acting Relay – 6.2 Bar (90 PSI)
Double Acting Relay – 10.3 Bar (150 PSI)
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 Gasses
Air, sweet natural gas, nitrogen and CO2
are acceptable supply gasses. Sour natural
gas is not acceptable. For Type nA and Type
tb installation only air or inert gas may be
connected to the air supply inlet.
