Technical Data

Fluid: Compressed air

Maximum pressure:

Transparent bowl:

10 bar (145 psig)

Metal bowl:

With manual or semi automatic drain: 17 bar (250 psig)

With automatic drain: 8 bar (116 psig)

Operating temperature*:

Transparent bowl: -20° to +50°C (0° to +125°F)

Metal bowl: -20° to +65°C (0° to +150°F)

* Air supply must be dry enough to avoid ice formation at temperatures below 2°C (35°F).

Partical removal: 5 µm, 25 µm or 40 µm. Within ISO 8573-1, Class

3 and Class 5

Typical flow at 10 bar (145 psig) inlet pressure, 6,3 bar

(90 psig) set pressure and a droop of 1 bar (15 psig) from set:

38 dm3/s (80 scfm)

Manual drain thread: 7/16-24 UNS male for 1/4" tube nut and

ferrule

Semi automatic drain connection: 8 mm (5/16") ID tube

Semi automatic drain operating pressure:

Drain closes when bowl pressure exceeds 0,1 bar (1.5 psig)

and opens when bowl pressure drops below 0,1 bar (1.5 psig).

Can be operated manually by lifting the stem.

Automatic drain connection: ISO R1/8

Automatic drain operating conditions:

Minimum flow to close drain: 0,14 dm3/s (0.3 scfm)

Drain closes when bowl pressure exceeds 0,7 bar (10 psig)

and opens when bowl pressure drops below 0,07 bar (1 psig).

Gauge ports:

1/8" PTF with PTF main ports

1/8" ISO Rc with ISO Rc main ports

Warning

These products are intended for use in industrial compressed air

systems only. Do not use these products where pressures and

temperatures can exceed those listed under ‘Technical Data’.

Before using these products with fluids other than those specified, for

non-industrial applications, life-support systems, or other applications not

within published specifications, consult NORGREN.

Through misuse, age, or malfunction, components used in fluid

power systems can fail in various modes. The system designer is warned

to consider the failure modes of all component parts used in fluid power

systems and to provide adequate safeguards to prevent personal injury or

damage to equipment in the event of such failure.

System designers must provide a warning to end users in the

system instructional manual if protection against a failure mode

cannot be adequately provided.

System designers and end users are cautioned to review specific

warnings found in instruction sheets packed and shipped with these

products.

Water vapor will pass through these units and will condense into

liquid if air temperature drops in the downstream system. Install an air

dryer if water condensation could have a detrimental effect on the

application.
