In previous articles focused on shaft aerators, we explained how to properly install these types of aerators, as well as providing troubleshooting hints and maintenance guidelines. A shaft aerator is but one type of aerator that can be used to provide septic aeration in your septic tank. A shaft aerator has an electrical motor attached to a stainless steel hollow shaft. Air is drawn through the shaft and distributed by the aspirator tip submerged in the wastewater. There are several other types of aerators. Choosing the best aerator for your application requires weighing the advantages and disadvantages that each type of aerator offers.
Shaft aerators do offer advantages that may make it the right choice for your application. For instance, the shaft aerator is installed inside the septic tank riser and so it is out of sight. Other types of aerators that operate outside the tank will require some type of camouflage to help them blend into the landscape. And because the shaft aerator is operating inside the tank, it operates more quietly. Sitting in the tank, the shaft aerator is also protected from the elements and extremes in weather. And since delivery of air into the septic tank wastewater is accomplished directly through the hollow shaft of the aerator, there is no need to run air hoses into the tank from and exterior pump so installation is less complicated.
The shaft aerator generally operates at low RPM and low Amps and so the operating cost can be lower than other types of aerators. Shaft aerators also generally have low amp mini-breakers that will protect the motor which not only provide a more reliable but a longer operating life as well.
