SECTION 4
MAINTENANCE
Blower efficiency and life depend on the quality of maintenance the blower receives. Maintenance must be done
regularly and with care. Clean work space, tools, solvents, and wiping rags are necessary to avoid transferring dirt into
the unit. A maintenance chart listing each blower is a valuable tool for scheduling regular checks of each unit. A good
program, well carried out, will insure long trouble-free service from the blower.
LUBRICATION
Gears and bearings are splash lubricated. The discharge end sump requires 2 quarts and the gear end sump requires 3
quarts of oil.
RECOMMENDED LUBRICANT
The factory recommended lubricant is AEON PD Synthetic Lubricant
. AEON PD is formulated especially for
positive displacement blower service to provide maximum blower 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.

NOTICE
Machines are shipped without oil in the sumps. Do not operate before adding lubricant.
LUBRICATION INSTRUCTIONS
Oil is add through the oil fill hole at the top of each bearing carrier. Check the oil level at both ends of the blower
daily. Add fresh oil as required to maintain the proper level. The oil level should be at the middle of the sight glass
when the machine is not operating.
Do not overfill as this will tend to cause excessive heading 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 conditions. Severe operating conditions may warrant more frequent oil changes. Laboratory
analysis of the oil 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 specifically
formulated for positive displacement blowers.
If you choose not to use AEON PD Synthetic Blower Synthetic Blower Lubricant, select an oil with rust and oxidation
inhibitors, anti-foam additives, and the viscosities listed in Figure 4-2. Do not use and oil that contains EP additivies.
NOTICE
Machines are shipped without oil in the sumps. Do not operate before adding lubricant.
Flush the oil whenever a change is made from one type of oil to another. Drain the currant lubricant as thoroughly as
possible. Refill with new lubricant. Fill to the normal level of the blower, which is the middle of the sight glass
