SL2 Mist Lubricators 83-950-000
By counting the number of drops per minute in the sight dome,
you can adjust to your requirements.
Every drop visible in the sight dome goes downstream.
Generally, one drop per minute downstream for every
10 - 15 SCFM flow is satisfactory.
25 drops per minute equals one (1) ounce per hour - volume
of oil passing through the sight dome.
NOTE: This is a constant density type lubricator which
delivers a constant ratio of oil to air flow. Therefore, if air
flow increases or decreases, oil delivery will be
adjusted propor tionately. ONLY IF A DIFFERENT
RATIO IS DESIRED SHOULD YOUR ADJUSTMENT KNOB
SETTING BE CHANGED AFTER YOUR INITIAL SETTING.
4. To replace fill plug, drip control, & service lubricator:
A. Turn off air supply and depressurize the unit.
B. Refer to pictorial for servicing and torque values.
C. Turn on air supply and check lubricator for leakage. If
leakage occurs, DO NOT OPERATE — conduct repairs
again.
Lightly grease with provided lubricant.
Inspect for nicks, scratches, and surface imperfections.
If present, reduced service life is probable and future replacement
should be planned.
Clean with lint-free cloth.

Operation and Service
Caution: Shut off air supply and exhaust the pressure
trapped within the lubricator before filling unit.
1. Remove the fill plug and fill the lubricator with the suggested
lubricant.
Suggested lubricant: F442
Petroleum based oil of 100 to 200 SSU viscosity at 100°F and
an aniline point greater than 200°F. (Mobil DTE24 and Sun
Company Sunvis 932 are good examples). Do not use oils
with adhesives, compound oils containing solvents, graphite,
detergents or synthetic oils.
2. Replace the fill plug (by turning clockwise) and seat firmly.
Excessive torque is not required. If leakage occurs, DO NOT
OPERATE — check to make sure the fill plug is installed
properly. The lubricator is now ready for setting.
3. Oil delivery adjustment — To adjust oil delivery, turn adjustment
knob on top of the lubricator.
Leaner — Clockwise
Richer — Counterclockwise
