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.
