1" Lubricator Series 2L300C
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.
Leaner — Clockwise
Richer — Counterclockwise
By counting the number of drops per minute in the sight dome,
you can adjust to your requirements.
Mist lubricator — 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 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.
