SECTION 4 
MAINTENANCE 

 

GENERAL

 

– 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 5-1/2 quarts and the gear 
end sump requires 5-1/2 quarts of oil.  Filling with this amount of oil will bring the oil level to about the 
middle of the sight gauge.  Add more oil if necessary to bring the level to the middle.  DO NOT OPERATE 
THE BLOWER UNLESS OIL LEVEL IS AT THE MIDDLE OF THE SIGHT GAUGE.  Do not overfill.  Oil is 
added through the oil fill hole at the top of each bearing carrier. 
 

RECOMMENDED LUBRICANT 

 
AEON PD Synthetic Blower Lubricant is recommended.  Refer to FIGURE 4-1, for AEON PD,  
AEON PD 

– FG (Food Grade) and AEON PD – XD (Extreme Duty) part numbers.   

 
AEON PD is formulated especially for positive displacement blower service to provide maximum blower 
protection at most temperatures.  Refer to FIGURE 4-2.  One filling of AEON PD will last a minimum of 4 
times longer than a premium mineral oil, depending on actual operating conditions.  Order AEON PD from 
your Gardner Denver distributor or call Gardner Denver directly.
