Blower Overhaul 101: What's Involved And Why It's Essential

Aeration blowers are vital to wastewater treatment plant performance—but even with strong preventative maintenance, these systems eventually require a full overhaul. This article explains why overhauls are essential, what they involve, and how to recognize the signs that one is due. It covers critical indicators such as elevated vibration, abnormal oil temperatures, leaking seals, and metal particles in oil samples. During an overhaul, certified professionals disassemble, inspect, clean, and rebuild the blower stage to factory specifications—replacing bearings, seals, and worn parts to restore the unit to like-new condition. Delaying this service can lead to catastrophic failure, especially as tolerances narrow and clearances degrade. To reduce downtime, some manufacturers offer exchange programs with pre-overhauled units ready to ship. With proper scheduling and support, blower overhauls offer a cost-effective way to extend equipment life, improve efficiency, and avoid unplanned outages—ultimately protecting both budgets and operations.
