SECTION 3
LUBRICATION
All DuroFlow blowers are splash oil lubricated at both
the gear and drive ends. Oil is distributed around the
gear housing and drive end chamber by the gears and
specially designed oil flingers.

RECOMMENDED LUBRICANT
The factory recommended lubricant is AEON PD
Synthetic Lubricant.
AEON PD is formulated
especially for positive displacement blowers to provide
maximum protection at any temperature. One filling of
AEON PD will last a minimum of 4 times longer than a
premium mineral oil, depending on actual operating
conditions. AEON PD contains a special additive
package designed for greater rust and corrosion
protection.

Machines are shipped without oil in
the sumps. Do not operate before
adding lubricant.
LUBRICATION INSTRUCTIONS
For 45 series models, the oil fill port is located on the
top of the blower at the driveshaft end (see
FIGURE 1-- 2, page 5).
The two oil sumps are
connected by a passageway through the housing
Add oil until the level stabilizes at the center of the sight-
glass(es).
Oil level at the sight glass must be
established when the blower is not operating.
Add fresh oil as required to maintain proper level.
Do not overfill as this will tend to
cause excessive heating of the gears,
oil to leak through the vent holes, 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 inhibi-
tors, anti--foam additives, and the viscosities listed in
FIGURE 3--3, page 12.
Do not use an oil that
contains EP additives.
