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.
