TECHNICAL DATA
Fluid: Compressed air
Maximum pressure:
Transparent bowl: 10 bar (150 psig)
Metal bowl: 17 bar (250 psig)
Operating temperature*:
Transparent bowl: -20° to +50°C (0° to +125°F)
Metal bowl: -20° to +80°C (0° to +175°F)
* Air supply must be dry enough to avoid ice formation
at temperatures below +2°C (+35°F).
Start point (minimum flow required for lubricator
operation) at 6,3 bar (90 psig) inlet pressure:
0,71 dm
3
/s (1.5 scfm)
Maximum recommended flow: 28 dm
3
/s (60 scfm). Air
flows above 28 dm
3
/s (60 scfm) create excessive air
velocity, turbulence, and pressure losses. In addition,
the fog produced by the lubricator will wet out on the
pipe walls and will not be carried by the compressed
air to the point of application.
Typical flow with 6,3 bar (90 psig) inlet pressure and 0,5
bar(7 psig) pressure drop:
Oil-Fog models: 75 dm
3
/s (158 scfm)
Micro-Fog models: 65 dm
3
/s (138 scfm)
Nominal bowl size: 0,1 litre (3.5 fluid ounce)
Manual drain connection: 1/8"
Materials:
Body: Aluminum
Bowl:
Transparent: Polycarbonate
Transparent with guard: Polycarbonate, steel guard
Metal: Aluminum
Metal bowl liquid level indicator lens: Transparent
nylon
Sight-Feed dome: Transparent nylon
Elastomers: Neoprene and nitrile

INSTALLATION
1. Shut-off air pressure. Install lubricator in air line -
l
vertically (reservoir down),
l
with air flow in direction of arrow on body,
l
downstream of filters and regulators
l
upstream of cycling valves,
l
as close as possible to the device being lubricated,
l
Oil-Fog Models - Not more than 5,2m (15 feet) from
the device being lubricated, and at the same height
or higher than the device.
2. Connect piping to proper ports using pipe thread
sealant on male threads only. Do not allow sealant to
enter interior of unit.
3. Push reservoir, or reservoir with guard, into body and
turn fully clockwise before pressurizing.
RECOMMENDED LUBRICANTS
Fill reservoir with a good quality, light, misting type oil
for compressed air tools. See Norgren publication N/
AL.8.900.935. Fill to maximum fill line on transparent
reservoirs. Oil level must always be visible in lens on
metal reservoirs. DO NOT OVERFILL.
FILL RESERVOIR (OIL-FOG LUBRICATORS)
Remove fill plug (2), add oil, and reinstall fill plug. Fill
plug can be removed and oil added without shutting off
air pressure to the lubricator.
NOTE: Oil fill plug (2) seals easily. Tighten finger-tight
only.
