Lubricating your PD Blower properly is one of the keys to longer life and reduced downtimes. Follow these instructions for best results.
DRIVE END LUBRICATION (For Grease – Splash Lube Blowers)
Drive end bearings are grease lubricated at the factory with Lithium Complex based grease. For relubrication, use Gardner Denver AEON PD Grease, Part Number 28H283. AEON PD Grease is a high temperature, high performance grease that is formulated with antiwear additives to provide superior service under the severe operating conditions of positive displacement blowers. It contains rust inhibitors which provide excellent protection against rust and corrosion.
If you choose not to use AEON PD Grease, select compatible base grease. The grease should be NLGI Grade 2 EP, contain rust inhibitors, and be suitable for blower discharge temperatures up to 350° F (177° C). Completely clean or purge the factory--filled grease from the blower. Do not mix different types of grease as they may not be compatible. Substitutions may cause early bearing failure.
Re-grease bearings every 500 hours of operation. Lubricate each bearing through the grease fittings located
at C in FIGURE 3-1 (2 places). When re-greasing, the old grease will be forced out of the vents
(E in FIGURE 3-1). To prevent damage to seals, these vents must be open at all times.
Do not over--grease bearings as this could cause premature bearing failure.
DRIVE END LUBRICATION (For Dual Splash Lube Blowers)
At the drive end, the bearings are lubricated by the slinger, which must be on the lowest rotor when in a vertical configuration.
Approximate oil sump capacities are listed in Figure 3-2.
Refer to Figure 3-1. Remove the breather (B) from the drive cover. Add oil to the drive sump until oil reaches the center of the oil level gauge (H). Secure breather (B) in the drive cover.
Add fresh oil as required to maintain proper level. The oil level should be at the middle of the sight glass when the machine is not operating. Refer to Figure 3-2, for approximate oil capacities.
GEAR END LUBRICATION (For Grease – Splash Lube and Dual Splash Lube Blowers)
At the gear end, the timing gear teeth are lubricated by being partially submerged in oil. The gear teeth serve as oil slingers for gear end bearings.
Approximate oil sump capacities are listed in Figure 3-2.
Do not overfill as this will tend to cause excessive heating of the gears and may damage the unit.
Machines are shipped without oil in the sump. Do not operate before adding lubricant.
Filling procedure Refer to FIGURE 3-1. Remove the breather (B) from the gear cover. Add oil to the gear case until oil reaches the center of the oil level gauge (H). Secure breather (B) in the gear cover.
Add fresh oil as required to maintain proper level. The oil level should be at the middle of the sight glass when the machine is not operating. Refer to Figure 3-2.
AEON PD is formulated especially for positive displacement blower service to provide maximum blower protection at any temperature. One fill of AEON PD will last a minimum of 4 times longer than a premium mineral oil. Refer to FIGURE 3-4.
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 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 specifically
formulated for positive displacement blowers. If you choose not to use AEON PD Synthetic Blower Lubricant,
select an oil with rust and oxidation inhibitors, anti-foam additives, and the viscosities listed in FIGURE 3-5.
Do not use an oil that contains EP additives.
Drain the current lubricant as thoroughly as possible. Refill with the new lubricant. Fill to normal level of the blower, which is at the middle of the sight glass when the machine is not operating. Run the blower for one hour. Shut off the blower and drain the lubricant completely. Refill the blower again with the new lubricant.
* For ambient temperatures less than 10° F, but not less than –20° F, the use of oil sump heaters, heated enclosures or synthetic lubricant is required.
** For ambient temperatures 10° F to 32° F, the use of oil sump heaters, heated enclosures or synthetic lubricant is recommended.
*** The lubricant viscosity must be 70 SUS minimum at the lubricant operating temperature.
The pour point of the lubricant should be at least 5° to 10° F below the minimum expected ambient temperature.
For continuous operation, where the lubricant temperature exceeds 200° F, synthetic lubricant is recommended.
