Warning
1. Do not introduce air from the outlet side as this can
damage the damper.
Warning
1. For the AL10/20 type, replenish the lubricant after
releasing the inlet pressure. Lubrication cannot take
place under a pressurized condition.
2. Adjustment of the
oil regulating valve for models
from the
AL20 to AL60 should be carried out ma-
nually. Turning it counterclockwise increases the
dripping amount,
and turning it clockwise reduces
the dripping amount.
The use of tools, etc. can re-
sult
in damage to the unit. From the fully closed po-
sition, three rotations
will bring it to the fully open
position. Please do not rotate it any further than this.
Note that the numbered
scale markings are guideli-
nes for adjusting the position, and not indicators of
the dripping amount.
Caution
1. Use a check valve (AKM series) to prevent back
flow of the lubricant when redirecting the air flow be-
fore the lubricator.
A portion of the air introduced from the IN side
pressurizes
the lubricant inside the bowl. The
remainder of the air passes through the needles o,
and flows to the OUT side. The pressure differential
between the
inside of the bowl and the inside of the
sight dome
w, causes the lubricant inside the bowl
into the
oil passage !0. The lubricant drips from the
dripping tube !1, and lubricates the OUT side. The
amount of lubricant
is adjusted by the needle o, on
the front face. Turning the
needle clockwise increases
the amount of the lubricant, and turning it
counterclockwise until fully opened shuts off the
lubricant. The needle on the side that is not used
should be left fully opened.

Caution
1. Check the dripping amount once a day. Drip failure
can cause damage to the components that need lu-
brication.
