Maintaining A Surface Based Dam Aerator

Installing a dam aeration system is the simplest, most effective way to improve water quality and surface based dam aerators come with the added benefit of creating an interesting display while they add oxygen to your water.

While this might seem easy, (and for the most part it is) aerating your dam, lake or other large water body isn’t a set and forget process.

Surface based dam aerators require a little more maintenance than their sub-surface dam aerator counterparts as organic material can build up on their motors.

If not dealt with when it first forms, the build up will become thick over time, causing strain on your motor which will eventually lead to over-heating and damage. This carries flow on effects, as, If your aerator becomes clogged or damaged, your water quality will decrease as its performance does, creating a vicious cycle of aerator damage and water quality degradation.

In fact, if you leave things for too long, you could end up with a water body that’s back to square one and an aerator that looks like this:






The purpose of your water body will determine how often exactly you need to check on your aerator and perform general cleaning and maintenance, but we would suggest doing so at least once a month (or having us do it for you if you’re not thrilled with the idea).

How do I keep my surface based dam aerator functioning in top shape?

  • Clear the shaft of the motor from any algae or sludge build up. This can be done by wiping it down.
  • Inspect the system for any damage caused by objects colliding with the aerator. It is important to check both your unit, and the float.
  • Check the electrical cable for any cuts or abrasions and test the voltage.
  • Check that the aerator’s operation is normal and the motor is not producing any strange noises.
  • Clear the motor housing.
  • Clear the nozzle from any build-up.

When properly maintained in this manner, your surface based dam aerator should continue to bring you improved water quality for years to come.

Note: Our Airolator dam aerators are powered by Franklin electric motors. This in itself means reduced maintenance requirements as the motors are not oil-filled and the oil doesn’t have to be topped up regularly. If you have a different type of aerator, please refer to your instruction manual for servicing requirements. You should also regularly check your panels and controller if operating a solar aeration system.
