Blower Lubrication
TEII - Wastewater Depot - Catalog Index - Blower Lubrication
| At the gear end the timing gear teeth are lubricated by being partially submerged in oil. the gear teeth serve as oil slinger for gear end bearings. At the drive end the bearings are grease lubricated. |
Filling Procedure |
| Refer to the figure above. Remove the oil level plug (H) and the square head vented oil fill plug (B) from the gear cover. Add oil to the gear case until oil drips out of the oil level hole (H). Secure plugs in their correct location. |
Lubrication Service |
| Add fresh oil as required to maintain proper level. If
premium grade mineral oil is used, the oil should be drained, the gearbox fulushed and the
oil replaced every 1500 hours or more frequently if inspection so indicates. The oil
drain plug is located at (A). With AEON PD synthetic blower lubricant, perform the
above oil-change maintenance after 4500 to 7500 hours. Bearings on the drive end of the blower require grease lubrication every 500 hours of operation. Lubricate the bearings through grease fittings located at (C). when regreasing, the old grease wil be forced out of the vents (E). To prevent damage to seals, these vents must be open at all times. |
| Warning |
| Do not overfill as this will tend to cause excessive heating of the gears and may damage the unit. |

| Gear End Lubrication |
| 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. Refer to the table below. |

| Warning |
| Servicing the air filters is one of the most important maintenance operations to be performed to insure long blower life. |
| Servicing frequency of filter elements is not time
predictable. A differential pressure indicator, with a continuous gauge reading,
should be installed across the inlet filter. It will tell how much of the service
life of the filter element has been used. It will also eliminate both premature
filter servicing and premature blower failure due to a plugged filter servicing and
premature blower failure due to a plugged filter when the filter pressure drop is used to
establish maintenance points. In all cases refer to the filter manufacturer's service instructions. Due to the many types of filters, it is not practical to give specific instructions covering all models. |
| Notice |
| No matter what type of filter is used, always make sure all seats, gaskets, clamps and hose connections on the filter and inlet line are absolutely aire tight. Each time the filter is serviced, inspect interior of the blower for dirt. |
