Failure to add oil to each end of the
blower on 70 series models will result
in damage to the blower.
The 70 series “C” design version with a column gauge
indicates the actual oil level during operation. The
column gauge before start--up should be filled to the
middle of the glass.
The oil level should be maintained at the center of the
glass while the blower is not operating. Add fresh oil as
required to maintain proper level.
The 70 series column sight glass needs to be
assembled at the position shown in FIGURE 3--3
below. The 70 series is generally built to vertical config-
uration. When converting to horizontal configuration,
the 1/4” tube needs to be trimmed to suit. Horizontal
configurations are built at the factory upon request
Do not overfill as this will tend to
cause excessive heating of the gears
and may damage the unit.
AEON PD Synthetic Lubricant should be drained after
6000 hours of operation. Re--fill with fresh AEON PD
oil. If mineral oil is used, perform the above oil--change
maintenance every 1500 hours. Recommended
service intervals are for normal blower operating condi-
tions. Severe operating conditions may warrant more
frequent oil changes. Laboratory analysis of lubricant
should be used to help determine the optimum oil
change interval.
For best performance and equipment protection, use
AEON PD Synthetic Lubricant, which has been specifi-
cally formulated for positive displacement blowers. If
you choose not to use AEON PD Synthetic Blower
Lubricant, select an oil with rust and oxidation inhib-
itors, anti--foam additives, and the viscosities listed in
FIGURE 3--4, page 13. Do not use an oil that contains
EP additives.
