Technical Data
Fluid: Compressed air
Maximum pressure: 290 psig (20 bar)
Operating temperature*: -30° to 150°F (-34° to 65°C)
* Air supply must be dry enough to avoid ice formation at temperatures below 35°F (2°C).
Typical flow at 150 psig (10 bar) inlet pressure, 90 psig (6.3 bar) set pressure and
a droop of 15 psig (1 bar) from set: 83 scfm (39 dm 3 /s)
Two inlet ports:
1/4" or 3/8" PTF
1/4" or 3/8" ISO Rc
1/4" or 3/8" ISO G
One outlet port:
1/4" PTF with PTF inlet ports
1/4" ISO Rc with ISO Rc inlet ports
1/4" ISO Rc with ISO G inlet ports
One gauge port:
1/8" PTF with PTF inlet ports
1/8" ISO Rc with ISO Rc inlet ports
