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

/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

/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

/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

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.
