Technical Data
Fluid: Compressed air
Inlet pressure range: 10 psig (0.7 bar) to 400 psig (27.6 bar) *
* For best performance, inlet pressure should be at least 10 psig (0.7 bar) greater than the desired
regulated pressure, but must not exceed the specified maximum.
Operating temperature: 0° to 175°F (-20° to 80°C) **
** Air supply must be dry enough to avoid ice formation at temperatures below 35°F (2°C).
Typical flow with a conventional pilot regulator at 100 psig (6.9 bar) inlet pressure,
90 psig (6.3 bar) set pressure, and a droop of 5 psig (0.35 bar) from set:
1/2" ports: 120 scfm (57 dm 3 /s)
