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).
0 - 100% non-condensing
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.
Single Acting Relay –
0.069 Nm³/h @ 1.5 bar
(0.041 SCFM @ 22 PSI)
0.082 Nm³/h @ 4.1 bar

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)
