Technical Data
Fluid: Compressed air
Maximum pressure: Transparent bowl: 150 psig (10 bar)
Metal bowl: Manual or semi automatic drain: 250 psig (17 bar)
Automatic drain: 150 psig (10 bar)
Operating temperature*: Transparent bowl: -30° to 125°F (-34° to 50°C)
Metal bowl: -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 ).
Particle removal: 5 µm, 25 µm or 40 µm. Within ISO 8573-1, Class 3 and Class 5
Typical flow at 150 psig (10 bar) inlet pressure, 90 psig (6.3 bar) set pressure and
a droop of 1 bar (15 psig) from set: 80 scfm (38 dm 3 /s)
Manual drain connection: Will fit 1/8-27 and 1/8-28 pipe thread
Semi automatic drain connection: Push on 5/16" (8 mm) ID tube
Semi automatic drain operating conditions (pressure operated):
Bowl pressure required to close drain: Greater than 1.5 psig (0.1 bar)
Bowl pressure required to open drain: Less than 1.5 psig (0.1 bar)
Minimum air flow required to close drain: 1 scfm (0.5 dm
3 /s)
Manual operation: Lift stem to drain bowl
Automatic drain connection: Will fit 1/8-27 and 1/8-28 pipe thread - Flexible tube
with 3/16" (5mm) minimum I.D. can be connected to the automatic drain. Drain
may fail to operate if the tube I.D. is less than 3/16" (5mm). Avoid restrictions in
the tube.
Automatic drain operating conditions (float operated):
Bowl pressure required to close drain: Greater than 5 psig (0.3 bar)
Bowl pressure required to open drain: Less than 3 psig (0.2 bar)
Minimum air flow required to close drain: 0.2 scfm (0.1 dm
3 /s)
Manual operation: Depress pin inside drain outlet to drain bowl
Gauge ports: 1/8"PTF with PTF main ports
1/8" ISO Rc with ISO Rc main ports
1/8" ISO Rc with ISO G main ports
Nominal bowl size: Bowl: 2.2 fluid ounce (65 ml)
Materials
Body: Zinc
Bonnet: Acetal
Valve: Brass
Bowl
Transparent: Polycarbonate
Guard for transparent bowl: Zinc
Metal bowl liquid level indicator lens:
Transparent nylon
Element: Sintered polypropylene
Elastomers: Neoprene and nitrile
An automatic drain is a two-way valve, which will close when the system is
pressurized. The drain opens when the float rises due to accumulated liquid
and on depressurization.
